However, the task of finding an appropriate transfer function is complex and time-consuming even for\r\nexperts. Thus, in many practical applications simpler techniques which do not rely on complex transfer functions\r\nare employed. One common example is Maximum Intensity Projection (MIP) which depicts the maximum value\r\nalong each viewing ray. In this paper, we introduce Maximum Intensity Difference Accumulation (MIDA), a new\r\napproach which combines the advantages of DVR and MIP. Like MIP, MIDA exploits common data characteristics\r\nand hence does not require complex transfer functions to generate good visualization results. It does, however,\r\nfeature occlusion and shape cues similar to DVR. Furthermore, we show that MIDA – in addition to being a useful\r\ntechnique in its own right – can be used to smoothly transition between DVR and MIP in an intuitive manner.\r\nMIDA can be easily implemented using volume raycasting and achieves real-time performance on current graphics\r\nhardware.", "authors_et_al": false, "substitute": null, "main_image": { "description": "Maximum Intensity

"title": "Semantic Visualization Mapping for Volume Illustration", "date": "2009", "abstract": "Scientific visualization is the discipline of automatically rendering images from\r\nscientific data. Adequate visual abstractions are important to show relevant information\r\nin the data. Visual abstractions are a trade-off between showing detailed\r\ninformation and preventing visual overload. To use visual abstractions for the\r\ndepiction of data, a mapping from data attributes to visual abstractions is needed.\r\nThis mapping is called the visualization mapping.\r\nThis thesis reviews the history of visual abstractions and visualizationmapping\r\nin the context of scientific visualization. Later a novel visual abstraction method\r\ncalled caricaturistic visualization is presented. The concept of exaggeration is the\r\nvisual abstraction used for caricaturistic visualization. Principles from traditional\r\ncaricatures are used to accentuate salient details of data while sparsely sketching\r\nthe context.\r\nThe visual abstractions described in this thesis are inspired by visual art and\r\nmostly by traditional illustration techniques. To make effective use of the recently\r\ndeveloped visualizationmethods, that imitate illustration techniques, an expressive\r\nvisualization mapping approach is required. In this thesis a visualization mapping\r\nmethod is investigated that makes explicit use of semantics to describe mappings\r\nfrom data attributes to visual abstractions. The semantic visualization mapping\r\nexplicitly uses domain semantics and visual abstraction semantics to specify visualization\r\nrules. Illustrative visualization results are shown that are achieved with\r\nthe semantic visualization mapping.\r\nThe behavior of the automatically rendered interactive illustrations is specified\r\nusing interaction-dependent visualization rules. Interactions like the change of the\r\nviewpoint, or the manipulation of a slicing plane are state of the art in volume\r\nvisualization. In this thesis a method for more elaborate interaction techniques is\r\npresented. The behavior of the illustrations is specified with interaction-dependent\r\nrules that are integrated in the semantic visualization mapping approach.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "image", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 373, "image_height": 410, "name": "rautek-2009-vmv-image.jpg", "type": "image/jpeg", "size": 36775, "path": "Publication:rautek-2009-vmv", "url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/rautek-2009-vmv-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/rautek-2009-vmv-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 488 ], "co_supervisor": [ 171 ], "date_end": "2009-01", "date_start": "2005-11", "rigorosum": "2009-01-27", "supervisor": [ 166 ], "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "", "filetitle": "image", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 373, "image_height": 410, "name": "rautek-2009-vmv-image.jpg", "type": "image/jpeg", "size": 36775, "path": "Publication:rautek-2009-vmv", "url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/rautek-2009-vmv-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/rautek-2009-vmv-image:thumb{{size}}.png" }, { "description": "", "filetitle": "paper", "main_file": true, "use_in_gallery": false, "access": "public", "name": "rautek-2009-vmv-paper.pdf", "type": "application/pdf", "size": 3330018, "path": "Publication:rautek-2009-vmv", "url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/rautek-2009-vmv-paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/rautek-2009-vmv-paper:thumb{{size}}.png" } ], "projects_workgroups": [ "exvisation" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2009/rautek-2009-vmv/", "__class": "Publication" }, { "id": "Rautek-2008-IDS", "type_id": "journalpaper", "tu_id": null, "repositum_id": null, "title": "Interaction-Dependent Semantics for Illustrative Volume Rendering", "date": "2008-05", "abstract": "In traditional illustration the choice of appropriate styles and rendering techniques is guided by the intention of\nthe artist. For illustrative volume visualizations it is difficult to specify the mapping between the 3D data and the visual representation that preserves the intention of the user. The semantic layers concept establishes this mapping with a linguistic formulation of rules that directly map data features to rendering styles. With semantic layers fuzzy logic is used to evaluate the user defined illustration rules in a preprocessing step.\nIn this paper we introduce interaction-dependent rules that are evaluated for each frame and are therefore computationally more expensive. Enabling interaction-dependent rules, however, allows the use of a new class of semantics, resulting in more expressive interactive illustrations. We show that the evaluation of the fuzzy logic can be done on the graphics hardware enabling the efficient use of interaction-dependent semantics.

Their production, however, is a difficult and expensive task. In recent years, three-dimensional imaging has become a vital tool not only in medical diagnosis and treatment planning, but also in many technical disciplines (e.g., material inspection), biology, and archeology. Modalities such as X-Ray Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) produce high-resolution volumetric scans on a daily basis. It seems counter-intuitive that even though such a wealth of data is available, the production of an illustration should still require a mainly manual and time-consuming process.\n\nThis thesis is devoted to the computer-assisted generation of illustrations directly from volumetric data using advanced visualization techniques. The concept of a direct volume illustration system is introduced for this purpose. Instead of requiring an additional modeling step, this system allows the designer of an illustration to work directly on the measured data. Abstraction, a key component of traditional illustrations, is used in order to reduce visual clutter, emphasize important structures, and reveal hidden detail. Low-level abstraction techniques are concerned with the appearance of objects and allow flexible artistic shading of structures in volumetric data sets.

There are many different ways to enhance depth perception, such as shading, contours, and shadows. Artists and illustrators frequently employ halos for this purpose. In this technique, regions surrounding the edges of certain structures are darkened or brightened which makes it easier to judge occlusion. Based on this concept, we present a flexible method for enhancing and highlighting structures of interest using GPU-based direct volume rendering. Our approach uses an interactively defined halo transfer function to classify structures of interest based on data value, direction, and position.

There are various different sensor systems on the market that can be used in these application fields, each having specific features in terms of accuracy, robustness, user interaction, operational range, measurement speed and frequency, resolution, or other relevant parameters. The selection of an appropriate sensor system for a particular application is not trivial.\r\n\r\nIn recent years research on image-based measurement systems and laser scanners has gained increasing interest – in many cases a combination of different sensors has advantages over a single-sensor system (e.g. different accuracy and reliability classes, different measurement range, etc.).\r\n\r\nThe point clouds produced by such systems potentially consist of a vast number of points. One of the main problems concerning the analysis and interpretation of deformation measurements is the visualization of the data respectively of the underlying deformation. In this paper we present the application of the recently developed caricaturistic visualization method to deformation data based on high density point clouds. Caricaturistic visualization depicts the deformation data in an exaggerated way. The exaggeration of the deformation accents subtle deviations and supports the viewer for the correct interpretation of the underlying deformation.

The\nillustration community has century-long experience in adapting their techniques to human\nperceptual needs in order to generate an effective depiction which conveys the desired\nmessage. Thus, their methods can provide us with important insights into visualization\nproblems.\nIn this tutorial, the concepts in illustrative visualization are reviewed. An important aspect here\nis interaction: while traditional illustrations are commonly only presented as static images,\ncomputer-assisted visualization enables interactive exploration and manipulation of complex\nscientific data. Only by coupling illustrative visualization with effective interaction techniques\nits full potential can be exploited.\nThe tutorial starts with a general introduction into the area of illustrative visualization. The\nconcept of importance-driven visualization and its applications are presented. Then we proceed with a discussion how traditional abstraction techniques can be applied in an\ninteractive context using importance-based methods. This ranges from low-level appearance\nto smart viewpoint-dependent visibility techniques such as cutaways or exploded views.\nFurther advanced manipulation strategies are discussed in the third part. The use\ndeformations to enhance visibility of certain features while providing context or to abstract the\nstructure of a complex objects through direct interaction with the data is examined. As many\nof the presented methods rely on a separation of focus and context, i.e., the important\nstructures in the data have been identified, the tutorial discusses approaches for selecting\nobjects of interest in a three-dimensional environment using intuitive sketch-based interfaces.\nSince the effectiveness of a user-interface is heavily dependent on the previous knowledge of\nthe user, the last part of the tutorial examines the concept of layering interfaces based on\nuser expertise. Finally, the application of illustrative display and interaction techniques for\nnon-traditional modalities such as mobile devices concludes the tutorial.\n\nIEEE Visualization 2007 Tutorial Page: http://vis.computer.org/vis2007/session/tutorials.html#t7\n\nSee also previous tutorials on Illustrative Visualization:\n\nIEEE Visualization 2006 Tutorial on Illustrative Visualization for Science and Medicine\nhttp://www.cg.tuwien.ac.at/research/publications/2006/tut-vis-2006/\n\nEurographics 2006 Tutorial on Illustrative Visualization for Science and Medicine http://www.cg.tuwien.ac.at/research/publications/2006/tut-eg-2006/\n\nSIGGRAPH 2006 Course on Illustrative Visualization for Science and Medicine http://www.cg.tuwien.ac.at/research/publications/2006/tut-siggraph-2006/\n\nIEEE Visualization 2005 Tutorial on Illustrative Visualization http://www.cg.tuwien.ac.at/research/publications/2005/Viola-vistutillustrativevis/\n\nEurographics 2005 Tutorial on Illustrative Visualization http://www.cg.tuwien.ac.at/research/publications/2005/eg-tut2005-iv/ \n", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 612, "image_height": 952, "name": "tut-vis-2007-.jpg", "type": "image/jpeg", "size": 124087, "path": "Publication:tut-vis-2007", "url": "https://www.cg.tuwien.ac.at/research/publications/2007/tut-vis-2007/tut-vis-2007-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2007/tut-vis-2007/tut-vis-2007-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 171, 161, 565, 564, 694 ], "research_areas": [ "IllVis" ], "keywords": [], "weblinks": [], "files": [ { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 612, "image_height": 952, "name": "tut-vis-2007-.jpg", "type": "image/jpeg", "size": 124087, "path": "Publication:tut-vis-2007", "url": "https://www.cg.tuwien.ac.at/research/publications/2007/tut-vis-2007/tut-vis-2007-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2007/tut-vis-2007/tut-vis-2007-:thumb{{size}}.png" } ], "projects_workgroups": [ "exvisation" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2007/tut-vis-2007/", "__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.

Following lectures describe the latest techniques in computerized illustration algorithms for scientific and medical data for both surface and volumetric data, covering\ntechniques from silhouette enhancement to stippling, to cut-away viewing, labeling, and focus+context rendering.\nEach of the lectures also discusses practical issues in making these techniques interactive and their use for different application domains. 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": "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.

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.

Whether\r\nused to teach a surgical or radiologic procedure, to illustrate normal\r\nor aberrant anatomy, or to explain the functioning of a technical\r\ndevice, illustration significantly impacts learning. Although\r\nmany specimens are readily available as volumetric data sets, particularly\r\nin medicine, illustrations are commonly produced manually\r\nas static images in a time-consuming process. Our goal is to\r\ncreate a fully dynamic three-dimensional illustration environment\r\nwhich directly operates on volume data. Single images have the\r\naesthetic appeal of traditional illustrations, but can be interactively\r\naltered and explored. In this paper we present methods to realize\r\nsuch a system which combines artistic visual styles and expressive\r\nvisualization techniques. We introduce a novel concept for direct\r\nmulti-object volume visualization which allows control of the appearance\r\nof inter-penetrating objects via two-dimensional transfer\r\nfunctions. Furthermore, a unifying approach to efficiently integrate\r\nmany non-photorealistic rendering models is presented. We discuss\r\nseveral illustrative concepts which can be realized by combining\r\ncutaways, ghosting, and selective deformation. Finally, we\r\nalso propose a simple interface to specify objects of interest through\r\nthree-dimensional volumetric painting. All presented methods are\r\nintegrated into VolumeShop, an interactive hardware-accelerated\r\napplication for direct volume illustration.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 768, "image_height": 768, "name": "bruckner-2005-VIS-image.jpg", "type": "image/jpeg", "size": 72208, "path": "Publication:bruckner-2005-VIS", "url": "https://www.cg.tuwien.ac.at/research/publications/2005/bruckner-2005-VIS/bruckner-2005-VIS-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2005/bruckner-2005-VIS/bruckner-2005-VIS-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 161, 166 ], "booktitle": "Proceedings of IEEE Visualization 2005", "date_from": "2005-10-23", "date_to": "2005-10-28", "editor": "C.

Whether used to teach a surgical or radiologic procedure, to illustrate normal or aberrant anatomy, or to explain the functioning of a technical device, illustration significantly impacts learning. Many specimen are readily available as volumetric data sets, particular in medicine. Illustrations, however, are commonly produced manually as static images in a time-consuming process. Our goal is to create a fully dynamic three-dimensional illustration environment which directly operates on volume data. Single images have the aesthetic appeal of traditional illustrations, but can be interactively altered and explored. We present methods to realize such a system which combines artistic visual styles and expressive visualization techniques. Our implementation exploits the latest generation of GPUs and, thus, is capable of handling commonly sized data sets at interactive frame rates.

Advanced schemes for importance compositing determine the resulting visibility of features and if the resulting visibility distribution does not correspond to the importance distribution different levels of sparseness are selected.\n\nThe applicability of importance-driven visualization is demonstrated\non several examples from medical diagnostics scenarios, flow visualization, and interactive illustrative visualization.
