The rendering performance is output sensitive, i.e., it scales with\nthe number of pixels rather than the complexity of the landscape. Given a height field of a terrain and a topographic map or similar data as input, the vegetation cover is extracted and stored on top of the height field in a preprocess, enhancing the terrain with forest canopies or other mesostructure. In addition, enhanced illumination models like shadowing and ambient occlusion can be calculated at runtime with reasonable computational cost, which greatly enhances the scene realism.

From these caveman paintings to mythological depictions\nof the ancient Egyptians, from medieval illuminated manuscripts\nto Leonardo Da Vinci’s anatomical studies in the Renaissance, drawings\nserved the purpose of transforming information into a visually perceptible\nform. Maybe it is this historical tradition that gives drawings the character\nof being perceived as beautiful by a widespread public. Maybe it is the abstract\nnature of drawings that lets them be an art form commonly chosen\nfor illustration. Often the first type of imagery we deal with in our lifetime\nare hand-drawn images in children’s books. So we literally grow up with\ndrawings as a familiar medium for depiction. This could also be a cause\nfor the high acceptance drawings usually meet.\nDrawings are commonly used in a scientific and educational context to convey\ncomplex information in a comprehensible and effective manner. Illustration\ndemands abstraction for focusing attention on important features by\navoiding irrelevant detail. Abstraction is a characteristic inherent in drawing,\nas a drawing always abstracts real world. Therefore drawings serve\nthe purpose of illustration very well. In addition to that, the expressiveness\nand attraction of drawings bestow them the property of communicating information\nin a way mostly felt as enjoyable.\nSpecific applications of volume visualization require exactly these visual\nproperties. Therefore increasing effort has been spent on developing and\napplying illustrative or non-photorealistic rendering methods for volume\nvisualization in recent years. This is the field of study this thesis is devoted\nto. The described capabilities of drawing make it the art form we\nchose to mimic for the non-photorealistic volume rendering approach developed\nin this thesis. A common shading technique in drawings is hatching.\nHatching is also standard practice in schematic hand-drawn illustrations\nas known from textbooks. We implemented a system capable of generating\nhatching drawings from volume datasets. The basic idea was to\nexploit illustrative and aesthetic excellence of hatching drawings for the\ncreation of expressive representations of volumetric data.\nThe drawing in Figure 1 gives an example of an illustration where hatching\nhas been used for shading. This figure shall demonstrate that hatching is\na technique capable of conveying spatial properties of the depicted object\nin an abstract and expressive way. It is an artwork of Vesalius’ De humani\ncorporis fabrica, a textbook of human anatomy from the Renaissance.\nWe propose some possible fields of application to further explain the motivation\nto engage in generating hatching drawings from three-dimensional\ndata. The majority of these data are generated in medical scanning devices,\nand medicine offers numerous possibilities for employing volume\nhatching. One possible medical application would be to illustrate upcoming\nsurgeries to patients. Explaining a surgery with the help of a volume\nhatching rendering is perhaps more comprehensible for a layman than with\ntomography slices. It also could be more readily accepted by patients as a\nrealistic rendering, due to the visually pleasing nature of hand drawings\nand the distaste of some people on viewing inner body parts realistically.\nAnother potential field of application for volume hatching is the automated\ngeneration of educational illustrations. Figures in scientific textbooks, for\ninstance in medicine or botany, which shall convey important structural\nfeatures by a schematic representation of objects, are often drawn by hand.\nThe preferred drawing medium here is pen-and-ink, and a reduced drawing\ntechnique is used where shading is realized with a sparse and even\nhatching. Volume hatching can be employed for creating images resembling\nsuch illustrations from volumetric data. On the one hand, this offers\nthe possibility for automated generation of still images for text- or schoolbooks.\nOn the other hand, interactive illustrations could be applied in\nteaching, since they provide exploration and examining possibilities while\ndepicting the objects in a familiar illustrative style.\nThis thesis is organized as follows. First, we give an overview about research\ndone in fields related to this thesis in Chapter 2. In Chapter 3 we\npresent the algorithms we developed for rendering hatching drawings from\nvolume data. This includes the creation of contour drawings, curvature\nestimation and generation of hatching strokes. We continue with shortly\noutlining the concept of implementing these algorithms in Chapter 4. In\nChapter 5 we present and discuss result images, revealing advantages and\nlimitations of our approach. We summarize the content of this thesis in\nChapter 6. Finally, we draw a conclusion on the results of this thesis and\npropose ideas for further enhancing our work in Chapter 7.", "authors_et_al": false, "substitute": null, "main_image": { "description": "image", "filetitle": "jpg", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 262, "image_height": 402, "name": "gerl-2006-vhi-jpg.jpg", "type": "image/jpeg", "size": 41458, "path": "Publication:gerl-2006-vhi", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/gerl-2006-vhi-jpg.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/gerl-2006-vhi-jpg:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 649 ], "matrikelnr": "0000000", "supervisor": [ 786, 166 ], "research_areas": [ "IllVis" ], "keywords": [], "weblinks": [], "files": [ { "description": "image", "filetitle": "jpg", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 262, "image_height": 402, "name": "gerl-2006-vhi-jpg.jpg", "type": "image/jpeg", "size": 41458, "path": "Publication:gerl-2006-vhi", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/gerl-2006-vhi-jpg.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/gerl-2006-vhi-jpg:thumb{{size}}.png" }, { "description": "paper", "filetitle": "pdf", "main_file": true, "use_in_gallery": false, "access": "public", "name": "gerl-2006-vhi-pdf.pdf", "type": "application/pdf", "size": 6139517, "path": "Publication:gerl-2006-vhi", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/gerl-2006-vhi-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/gerl-2006-vhi-pdf:thumb{{size}}.png" } ], "projects_workgroups": [ "vis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/gerl-2006-vhi/", "__class": "Publication" }, { "id": "bruckner-2006-ICE", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": null, "title": "Illustrative Context-Preserving Exploration of Volume Data", "date": "2006-11", "abstract": "In volume rendering it is very difficult to simultaneously visualize\ninterior and exterior structures while preserving clear shape cues.\nHighly transparent transfer functions produce cluttered images with\nmany overlapping structures, while clipping techniques completely\nremove possibly important context information.

The user selects a focus, i.e., object of interest, from a set of pre-defined features. Our system automatically determines the most expressive view on this feature. A characteristic viewpoint is estimated by a novel information-theoretic framework which is based on the mutual information measure. Viewpoints change smoothly by switching the focus from one feature to another one. This mechanism is controlled by changes in the importance distribution among features in the volume. The highest importance is assigned to the feature in focus. Apart from viewpoint selection, the focusing mechanism also steers visual emphasis by assigning a visually more prominent representation. To allow a clear view on features that are normally occluded by other parts of the volume, the focusing for example incorporates cut-away views.", "authors_et_al": false, "substitute": null, "main_image": { "description": "image", "filetitle": "jpg", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 578, "image_height": 406, "name": "vis-foa-jpg.jpg", "type": "image/jpeg", "size": 54181, "path": "Publication:vis-foa", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-jpg.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-jpg:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 171, 608, 207, 166 ], "journal": "IEEE Transactions on Visualization and Computer Graphics", "lecturer": [ 171 ], "number": "5", "pages_from": "933", "pages_to": "940", "volume": "12", "research_areas": [], "keywords": [ "illustrative visualization", "interacting with volumetric datasets", "optimal viewpoint estimation", "focus+context techniques", "volume visualization" ], "weblinks": [], "files": [ { "description": "video", "filetitle": "avi", "main_file": false, "use_in_gallery": false, "access": "public", "name": "vis-foa-avi.avi", "type": "", "size": 29168640, "path": "Publication:vis-foa", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-avi.avi", "thumb_image_sizes": [] }, { "description": "image", "filetitle": "jpg", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 578, "image_height": 406, "name": "vis-foa-jpg.jpg", "type": "image/jpeg", "size": 54181, "path": "Publication:vis-foa", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-jpg.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-jpg:thumb{{size}}.png" }, { "description": "paper", "filetitle": "pdf", "main_file": true, "use_in_gallery": false, "access": "public", "name": "vis-foa-pdf.pdf", "type": "application/pdf", "size": 585521, "path": "Publication:vis-foa", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-pdf:thumb{{size}}.png" }, { "description": "slides", "filetitle": "ppt", "main_file": false, "use_in_gallery": false, "access": "public", "name": "vis-foa-ppt.zip", "type": "application/x-zip", "size": 10090882, "path": "Publication:vis-foa", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/vis-foa-ppt.zip", "thumb_image_sizes": [] } ], "projects_workgroups": [ "GameTools", "exvisation" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/vis-foa/", "__class": "Publication" }, { "id": "CADIK-2006-IAQ", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Image Attributes and Quality for Evaluation of Tone Mapping Operators", "date": "2006-10", "abstract": "The problem of reproducing high dynamic range images\non devices with restricted dynamic range has gained a lot\nof interest in the computer graphics community.

As a result of the CTA scanning, a set of 1200–2000 transverse slices is\r\nacquired, depicting vessels enhanced by means of an intravenously injected contrast medium. The number of\r\nslices is high and therefore their manual examination is laborious and lengthy. As a remedy, post-processing\r\nmethods were developed to allow faster and more intuitive visualization of the imaged vascularity. However,\r\nsimple visualization by means of the traditional techniques as maximum-intensity projection (MIP) or direct\r\nvolume rendering (DVR) is hampered due to the presence of bones in the dataset, which occlude the vessels.\r\nTherefore, a sequence of operations—the processing pipeline—is needed, leading to generation of clinically\r\nrelevant images which depict unobstructed vessels.\r\n\r\nIn the first step of the pipeline the dataset is segmented and the tissues are classified, to allow subsequent\r\nvessel identification and bone removal. This is a complex task because of high density and spatial variability of\r\nthe tissues. Traditional image processing techniques do not deliver acceptable results and therefore in the thesis\r\nwe present new approaches that introduce additional ’anatomic’ information into the segmentation and classification\r\nprocess. We propose a probabilistic atlas which enables modeling of spatial and density distributions of\r\nvessel and bone tissues in datasets, to allow their improved classification. In the atlas construction the non-rigid\r\nthin-plate spline warping and registration of the datasets are applied, to address the high anatomic variability\r\namong the patients. The concept of the atlas is further extended by means of the watershed transform, to further\r\nimprove precision of the registration procedure. Alternatively, we propose and evaluate a technique for vessel\r\nenhancement based on Hessian filtering to allow detection and recognition of vessel structures without operator\r\nsupervision.\r\n\r\nIn the second step a geometric model of the vessel tree is constructed to derive information about the vessel\r\ncenterlines. Here, an already available algorithm based on the so-called vessel-tracking, implemented by means\r\nof optimal path searching, is exploited with improvements to make the geometric model more precise.\r\n\r\nThe third step of the processing pipeline—visualization—requires this model, since its results can be significantly\r\ninfluenced by a potential imperfections, bringing in clinically misleading images. To address limitations\r\nof the vessel visualization by means of the existing techniques as MIP, CPR or DVR we propose their generalization\r\nin form of a focus & context-based concept called VesselGlyph. VesselGlyph enables to combine\r\nintuitively and systematically various visualization techniques to single a image to allow better, more comprehensive\r\nand unoccluded view of vessels for the diagnostic purposes.\r\n\r\nTo support the design and development of the proposed segmentation, modeling and visualization algorithms\r\nand to enable their application in the clinical environment, we implemented a set of tools grouped in the AngioVis\r\nToolBox software. Within this application, individual steps of the processing pipeline are accomplished.\r\nThe toolbox is complemented with additional utilities constituting together a fully-functional medical workstation\r\nsoftware which is regularly used to process patient data on a daily basis in the clinical environment.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "", "main_file": true, "use_in_gallery": true, "access": "public", "image_width": 300, "image_height": 297, "name": "straka-phd-thesis-.jpg", "type": "image/jpeg", "size": 19133, "path": "Publication:straka-phd-thesis", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/straka-phd-thesis-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/straka-phd-thesis-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 167 ], "co_supervisor": [ 166 ], "date_end": "2006-08", "date_start": "2002-04", "rigorosum": "2006-08-27", "supervisor": [ 693 ], "research_areas": [], "keywords": [ "Visualization", "Medial Data Processing", "Segmentation", "Vessel Modeling", "3D Reconstruction", "Vessel Visualization" ], "weblinks": [], "files": [ { "description": "", "filetitle": "", "main_file": true, "use_in_gallery": true, "access": "public", "image_width": 300, "image_height": 297, "name": "straka-phd-thesis-.jpg", "type": "image/jpeg", "size": 19133, "path": "Publication:straka-phd-thesis", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/straka-phd-thesis-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/straka-phd-thesis-:thumb{{size}}.png" }, { "description": "", "filetitle": "pdf", "main_file": true, "use_in_gallery": true, "access": "public", "name": "straka-phd-thesis-pdf.pdf", "type": "application/pdf", "size": 51788783, "path": "Publication:straka-phd-thesis", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/straka-phd-thesis-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/straka-phd-thesis-pdf:thumb{{size}}.png" } ], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/straka-phd-thesis/", "__class": "Publication" }, { "id": "WIMMER-2006-IP", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Instant Points: Fast Rendering of Unprocessed Point Clouds", "date": "2006-07", "abstract": "We present an algorithm to display enormous unprocessed point clouds\nat interactive rates without requiring long preprocessing.

Indirect\r\nmethods require to transform the initial volumetric model into an\r\nintermediate geometrical model in order to efficiently visualize it.\r\nIn contrast, direct volume rendering (DVR) methods can directly\r\nprocess the volumetric data. Modern CT scanners usually provide data as a set of samples on a rectilinear\r\ngrid, which is computed from the measured projections by discrete tomographic reconstruction. Therefore the rectilinear grid can already be considered as an intermediate volume representation. In this paper we introduce direct direct volume rendering (D²VR). D²VR does not require a rectilinear grid, since it is based on an immediate\r\nprocessing of the measured projections. Arbitrary samples for ray\r\ncasting are reconstructed from the projections by using the Filtered\r\nBack-Projection algorithm.

Most noteworthy, the use of dedicated\r\ngraphics accelerator hardware has found its way from the professional to the consumer\r\nmarket, and their ever increasing power has allowed for rendering almost\r\nphotorealistic virtual environments while still maintaining interactive framerates.\r\nDespite this rapid development, a significant element of computer graphics has been\r\nneglected for a long time. Shadows do not only provide more realistic-looking scenes,\r\nbut also aid the viewer in perceiving spatial relationships. However, due to the additional\r\ncomputational requirements, it has been impossible for graphics accelerators\r\nto render shadows and keep framerates high enough to maintain the feeling of immersion\r\nfor a long time. Although there are several approaches to realize shadows,\r\ndynamic environments with a multitude of light sources and complex objects still\r\nmake high demands on the hardware.\r\nIn this thesis, a technique is presented to improve the performance of shadow volumes\r\nin complex scenes that consist of a large number of individual objects. Several\r\noptimization techniques have already been proposed that target applications where\r\nthe rasterization of the shadow volume polygons is the main bottleneck. However,\r\nthese optimizations usually assume that the number of individual objects in the\r\nscene is rather small compared to the number of geometric primitives (triangles). In\r\nsuch scenes, calculations can be accelerated by using low-polygon approximations\r\nof the actual geometry. Most of these existing optimization techniques relieve the\r\ngraphics hardware at the cost of increased CPU load. If the CPU is already at peak\r\nload, these techniques do not achieve any performance gain, but rather worsen the\r\nbottleneck in the CPU stage, resulting in an even lower performance.\r\nThis thesis first presents an overview of current state-of-the-art shadowing techniques\r\nthat are based on standard shadow volumes. Then, we will try to adapt\r\nparts of these techniques to work in complex scenes. Specifically, we will improve\r\nvisibility determination for shadow volume culling in GPU-demanding scenes with\r\nlots of individual objects, as well as present a method for the fast creation of segmented\r\n(clamped) shadow volumes that tightly fit the shadow-receiving geometry\r\nusing vertex programs (shaders).", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 617 ], "supervisor": [ 193 ], "research_areas": [], "keywords": [ "shadow volumes", "coherent hierarchical culling", "cc shadow volumes", "real-time rendering" ], "weblinks": [], "files": [ { "description": "", "filetitle": "thesis", "main_file": true, "use_in_gallery": false, "access": "public", "name": "STEINER-2006-SVC-thesis.pdf", "type": "application/pdf", "size": 5750333, "path": "Publication:STEINER-2006-SVC", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/STEINER-2006-SVC/STEINER-2006-SVC-thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/STEINER-2006-SVC/STEINER-2006-SVC-thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "rend" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/STEINER-2006-SVC/", "__class": "Publication" }, { "id": "Wimmer-2006", "type_id": "inbook", "tu_id": null, "repositum_id": null, "title": "Robust Shadow Mapping with Light Space Perspective Shadow Maps", "date": "2006-03", "abstract": "In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and\r\nuniform shadow maps.

The modeling stage could be described as shaping individual objects that are later used in the scene. For many years scientists are trying to create an appropriate model of the blood vessels. It looks quite intuitive to believe that a blood vessel can be modeled as a tubular object, and this is true, but the problems appear when you want to create an accurate model that can deal with the wide variability of shapes of diseased blood vessels. From the medical point of view it is quite important to identify, not just the center of the vessel lumen but also the center of the vessel, particularly in the presences of some anomalies, which is the case diseased blood vessels.\r\n\r\nAn accurate estimation of vessel parameters is a prerequisite for automated visualization and analysis of healthy and diseased blood vessels. We believe that a model-based technique is the most suitable one for parameterizing blood vessels. The main focus of this work is to present a new strategy to parameterize diseased blood vessels of the lower extremity arteries.\r\n\r\nThe first part presents an evaluation of different methods for approximating the centerline of the vessel in a phantom simulating the peripheral arteries. Six algorithms were used to determine the centerline of a synthetic peripheral arterial vessel. They are based on: ray casting using thresholds and a maximum gradient-like stop criterion, pixel-motion estimation between successive images called block matching, center of gravity and shape based segmentation. The Randomized Hough Transform and ellipse fitting have been used as shape based segmentation techniques. Since in the synthetic data set the centerline is known, an estimation of the error can be calculated in order to determine the accuracy achieved by a given method.\r\n\r\nThe second part describes an estimation of the dimensions of lower extremity arteries, imaged by computed tomography. The vessel is modeled using an elliptical or cylindrical structure with specific dimensions, orientation and CT attenuation values. The model separates two homogeneous regions: Its inner side represents a region of density for vessels, and its outer side a region for background. Taking into account the point spread function of a CT scanner, which is modeled using a Gaussian kernel, in order to smooth the vessel boundary in the model. An optimization process is used to find the best model that fits with the data input. The method provides center location, diameter and orientation of the vessel as well as blood and background mean density values.\r\n\r\nThe third part presents the result of a clinical evaluation of our methods, as a prerequisite step for being used in clinical environment. To perform this evaluation, twenty cases from available patient data were selected and classified as 'mildly diseased' and 'severely diseased' datasets. Manual identification was used as our reference standard. We compared the model fitting method against a standard method, which is currently used in the clinical environment. In general, the mean distance error for every method was within the inter-operator variability. However, the non-linear model fitting technique based on a cylindrical model shows always a better center approximation in most of the cases, 'mildly diseased' as well as 'severely diseased' cases. Clinically, the non-linear model fitting technique is more robust and presented a better estimation in most of the cases. Nevertheless, the radiologists and clinical experts have the last word with respect to the use of this technique in clinical environment.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "pdf", "main_file": true, "use_in_gallery": true, "access": "public", "name": "Cruz-thesis-pdf.pdf", "type": "application/pdf", "size": 7916402, "path": "Publication:Cruz-thesis", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Cruz-thesis/Cruz-thesis-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Cruz-thesis/Cruz-thesis-pdf:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 168 ], "date_end": "2006-03", "date_start": "2002-05", "supervisor": [ 166 ], "research_areas": [], "keywords": [ "Vessel Visualization", "3D Modeling", "Segmentation", "3D Reconstruction" ], "weblinks": [], "files": [ { "description": "", "filetitle": "pdf", "main_file": true, "use_in_gallery": true, "access": "public", "name": "Cruz-thesis-pdf.pdf", "type": "application/pdf", "size": 7916402, "path": "Publication:Cruz-thesis", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Cruz-thesis/Cruz-thesis-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Cruz-thesis/Cruz-thesis-pdf:thumb{{size}}.png" } ], "projects_workgroups": [ "AngioVis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Cruz-thesis/", "__class": "Publication" }, { "id": "kim-2006-tang", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "A Tangible User Interface System for CAVE Applications", "date": "2006-03", "abstract": "", "authors_et_al": false, "substitute": null, "main_image": { "description": "image", "filetitle": "jpg", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 282, "image_height": 205, "name": "kim-2006-tang-jpg.jpg", "type": "image/jpeg", "size": 26105, "path": "Publication:kim-2006-tang", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/kim-2006-tang-jpg.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/kim-2006-tang-jpg:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 624, 581, 625, 235, 580 ], "booktitle": "Proceedings of IEEE Virtual Reality", "date_from": "2006-03-25", "date_to": "2006-03-29", "lecturer": [ 581 ], "location": "Alexandria, Virginia, USA", "publisher": "IEEE", "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "image", "filetitle": "jpg", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 282, "image_height": 205, "name": "kim-2006-tang-jpg.jpg", "type": "image/jpeg", "size": 26105, "path": "Publication:kim-2006-tang", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/kim-2006-tang-jpg.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/kim-2006-tang-jpg:thumb{{size}}.png" }, { "description": "paper", "filetitle": "pdf", "main_file": true, "use_in_gallery": false, "access": "public", "name": "kim-2006-tang-pdf.pdf", "type": "application/pdf", "size": 647640, "path": "Publication:kim-2006-tang", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/kim-2006-tang-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/kim-2006-tang-pdf:thumb{{size}}.png" } ], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/kim-2006-tang/", "__class": "Publication" }, { "id": "tut-vis-2006", "type_id": "misc", "tu_id": null, "repositum_id": null, "title": "IEEE Visualization Tutorial on Illustrative Visualization for Science and Medicine", "date": "2006", "abstract": "This tutorial presents recent research and developments from academia in illustrative visualization focusing on its use for medical/science subjects.

We begin in the morning with a lecture presenting an overview of traditional illustration for\ntechnical, scientific, and medical subjects. This is followed by a description of the main components in an illustrative visualization pipeline for developing systems to assist technical\nand scientific illustrators. The tutorial progresses with an overview of the techniques used in illustration as well as approaches to evaluate their use and effectiveness. The morning concludes with the start of the “viewing and rendering” section. The three lectures in this section describe the latest approaches in computerized illustration algorithms for scientific and medical data for both surface and volumetric data, covering techniques from silhouette enhancement to stippling, to cut-away viewing, labeling, and focus+context rendering. Each of the lectures also discusses practical issues in making these techniques interactive and their use for different application domains. The tutorial includes a trained medical illustrator discussing the principles/caveats/issues in using illustration techniques in real-world medical applications. This lecture will also describe an evaluation, from an illustrator’s point of view, of the use and quality of the techniques presented throughout the day.

Tutorial concludes with discussion on specific medical case studies where the illustrative visualization has been effectively applied.\n\nEurographics 2006 tutorial page:\nhttp://www.cg.tuwien.ac.at/events/EG06/program-t1022.php\n\nSee also previous tutorials on Illustrative Visualization:\n\nSIGGRAPH 2006 Course on Illustrative Visualization for Science and Medicine\nhttp://www.cg.tuwien.ac.at/research/publications/2006/tut-siggraph-2006/\n\nIEEE Visualization 2005 Tutorial on Illustrative Visualization\nhttp://www.cg.tuwien.ac.at/research/publications/2005/Viola-vistutillustrativevis/\n\nEurographics 2005 Tutorial on Illustrative Visualization\nhttp://www.cg.tuwien.ac.at/research/publications/2005/eg-tut2005-iv/", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 281, "image_height": 300, "name": "tut-eg-2006-.png", "type": "image/png", "size": 54466, "path": "Publication:tut-eg-2006", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 171, 565, 564, 563, 596, 631, 633 ], "research_areas": [ "IllVis" ], "keywords": [], "weblinks": [], "files": [ { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 281, "image_height": 300, "name": "tut-eg-2006-.png", "type": "image/png", "size": 54466, "path": "Publication:tut-eg-2006", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-:thumb{{size}}.png" }, { "description": "Smart Visibility in Visualization and Importance-Driven Retargeting", "filetitle": "Slides", "main_file": false, "use_in_gallery": false, "access": "public", "name": "tut-eg-2006-Slides.zip", "type": "application/x-zip", "size": 54741002, "path": "Publication:tut-eg-2006", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-Slides.zip", "thumb_image_sizes": [] }, { "description": "Overview and complete notes to each contribution", "filetitle": "Tutorial Notes", "main_file": true, "use_in_gallery": false, "access": "public", "name": "tut-eg-2006-Tutorial Notes.pdf", "type": "application/pdf", "size": 9880748, "path": "Publication:tut-eg-2006", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-Tutorial Notes.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/tut-eg-2006-Tutorial Notes:thumb{{size}}.png" } ], "projects_workgroups": [ "exvisation" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/", "__class": "Publication" }, { "id": "zotti-2006-dgm", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": null, "title": "A Sky Dome Visualisation for Identification of Astronomical Orientations", "date": "2006", "abstract": "It has long been known that ancient temples were frequently oriented\n along the cardinal directions or to certain points along the horizon\n where the Sun or the Moon rises or sets on special days of the year.

Application scenario for the presented work is variance comparison and\r\ndimensional measurement of homogeneous industrial components in industrial high resolution 3D computed\r\ntomography (3D-CT). We propose a pipeline which uses common 3D image processing filters for pre-processing\r\nand segmentation of 3D-CT datasets in order to create the surface model. In particular, a pre-filtering step\r\nreduces noise and artefacts without blurring edges in the dataset. A watershed filter is applied on the gradient\r\ninformation of the smoothed data to create a binary dataset.

Articular cartilage is a very thin\r\nstructure covering the endings of human bones. Thus, even slight changes in its\r\nthickness and inner structure may indicate an occurrence or progress of degeneration.\r\nThe early detection of these factors is crucial for diagnosis and treatment of\r\ncartilage degeneration. Research to find treatments to stop or even reverse these\r\ndegenerative changes is well in progress.\r\nMagnetic resonance imaging is currently the best and most used non-invasive\r\ntechnique for acquisition of soft tissue structures like articular cartilage. In this\r\nwork we use two types of data: a high-resolution anatomical scan of the cartilage\r\nand a T2 map, which is computed from a set of sequences with varying parameters.\r\nWhile the thickness of the data can be precisely assessed fromthe anatomical scan,\r\nthe T2 map offers information on the inner structures of the cartilage.\r\nSince the femoral cartilage is a curved thin-wall structure with a relatively\r\nsmall extent in one direction, it is very difficult to estimate its thickness from a\r\nstack of slices or even from a three-dimensional reconstruction of its surface. We\r\ndiscuss inspection of the tissue by unfolding and, thus, representing the tissue as\r\na two-dimensional height field. Such a transformation of the object enables the\r\napplication of 2D geometrical operations in order to observe subtle details in the\r\nthickness of the tissue.\r\nNowadays scanners allow a quality assessment checking disruptions in the\r\npattern of the T2 map of the patellar cartilage. The T2 map illustrates the quality of\r\nthe cartilage and changes in the pattern of T2 map indicate defects before changes\r\nin the thickness itself occur. We propose the Profile Flags - an intuitive interface\r\nfor probing of the T2 maps by browsing the reconstructed surface of the cartilage.\r\nThe Profile Flag is positioned on the reconstructed surface of the tissue, and can\r\nbe moved along it. The Profile Flags can be applied to annotate local as well as\r\nglobal characteristics of the underlying data in a single still image. Furthermore,\r\nwe present a set of extensions to Profile Flags for selection, classification and\r\nautomatic positioning. Profile Flags can also be used to measure time-varying\r\ndynamic contrast enhanced magnetic resonance imaging data.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "pdf", "main_file": true, "use_in_gallery": false, "access": "public", "preview_image_width": 229, "preview_image_height": 299, "name": "Mlejnek_2006_MVOA-pdf.pdf", "type": "application/pdf", "size": 13563571, "path": "Publication:Mlejnek_2006_MVOA", "preview_name": "Mlejnek_2006_MVOA-pdf:preview.png", "preview_type": "image/jpeg", "preview_size": 54051, "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mlejnek_2006_MVOA/Mlejnek_2006_MVOA-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mlejnek_2006_MVOA/Mlejnek_2006_MVOA-pdf:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 179 ], "date_end": "2006", "date_start": "2003", "supervisor": [ 166 ], "research_areas": [], "keywords": [ "applications of visualization", "visualization in medicine" ], "weblinks": [], "files": [ { "description": "", "filetitle": "pdf", "main_file": true, "use_in_gallery": false, "access": "public", "preview_image_width": 229, "preview_image_height": 299, "name": "Mlejnek_2006_MVOA-pdf.pdf", "type": "application/pdf", "size": 13563571, "path": "Publication:Mlejnek_2006_MVOA", "preview_name": "Mlejnek_2006_MVOA-pdf:preview.png", "preview_type": "image/jpeg", "preview_size": 54051, "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mlejnek_2006_MVOA/Mlejnek_2006_MVOA-pdf.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mlejnek_2006_MVOA/Mlejnek_2006_MVOA-pdf:thumb{{size}}.png" } ], "projects_workgroups": [ "COMRADE" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mlejnek_2006_MVOA/", "__class": "Publication" }, { "id": "Pajer-2006-tmcg", "type_id": "studentproject", "tu_id": null, "repositum_id": null, "title": "Modern Texture Mapping in Computer Graphics", "date": "2006", "abstract": "Textures have a variety of applications in computer graphics.

"Caricaturistic Visualization", "date": "2006", "abstract": "For many applications of medicine and life science, data is gathered or measured to find and to analyze the characteristics of the investigated object. Characteristics of a dataset can be expressed as the deviations from the norm. These deviations traditionally are found and classified using statistical methods. In many cases the statistical models do not appropriately describe the underlying phenomenon. They are therefore unsuitable for the data of interest. In this case visualization can replace the statistical methods. Expressive visualizations guide the user to find characteristics. Further the user is enabled to analyze the deviations of a given dataset.\r\nCaricaturistic visualization is an expressive method tailored to depict the deviations in an exaggerated way. It is guided by the idea of caricatures which exaggerate the outstanding features of an object. A method for caricaturistic visualization is presented and its power is shown on different examples. Caricaturistic visualization assumes the existence of a reference model. In many applications an explicit reference model is not available. To overcome this limitation different datasets are compared to each other. This results in the Caricature matrix, a 2D matrix of caricaturistic visualizations.

The proposed framework allows visualization\r\nexperts to design high-level transfer function models which can intuitively be used by non-expert users.

A point cloud is simply a set of unconnected 3D coordinates in cartesian space. Each coordinate of such a set is interpreted as a point in space. A point cloud is the result of a sampling process, where either a laser scanner samples a real environment, or the data structure of some already existing graphical model is point sampled. During rendering it is attempted to reconstruct the sampled\r\nmodel from the given point cloud. The algorithm presented in this thesis builds on two new data structures, namely Memory Optimized Sequential Point Trees and Nested Octrees. It includes an out-of-core part, which means that it is also possible to render models that do not fit in the main memory of the computer, and\r\nan occlusion-culling part, which means that objects, which are hidden by objects closer to the viewer, do not have to be rendered. The algorithm is developed primarily for the fast rendering of point clouds, i.e., with a high frame rate, whereas the visual quality of the rendered point clouds is not in the focus of this work.
