Recently, screen-space ambient\nocclusion (SSAO) methods, which sample the frame buffer as a discretization of the scene geometry, have become\nvery popular for real-time rendering. We present temporal SSAO (TSSAO), a new algorithm which exploits\ntemporal coherence to produce high-quality ambient occlusion in real time. Compared to conventional SSAO,\nour method reduces both noise as well as blurring artifacts due to strong spatial filtering, faithfully representing\nfine-grained geometric structures. Our algorithm caches and reuses previously computed SSAO samples, and\nadaptively applies more samples and spatial filtering only in regions that do not yet have enough information\navailable from previous frames. The method works well for both static and dynamic scenes.", "authors_et_al": false, "substitute": null, "main_image": { "description": "ssao", "filetitle": "image-buddha", "main_file": false,

Even very sophisticated visualization systems,\r\nthat offer a wide variety of interaction possibilities and exhibit complex user\r\ninterfaces, do usually not make use of additional advanced input and output devices.\r\nThe interaction is typically limited to the computer mouse and a keyboard. One of\r\nthe reasons for the lack of advanced interaction devices is the high cost of special\r\nhardware.\r\nThis thesis introduces the idea of Augmented Visualization. The aim of the\r\nproject is to develop a novel interaction solution for projection walls as well as PC\r\nmonitors using cheap hardware such as mobile phones or tablets. Several features\r\nof mobile devices will be exploited to improve the interaction experience. The main\r\ntechnical challenge of the project is to implement a solution for markerless visual\r\ntracking of the changing visualized scene. In the proposed setup, this also requires\r\nreal-time wireless video streaming between the mobile device and the PC. The realtime\r\ntracking of the visualized scene will allow to estimate the six-degrees-of-freedom\r\npose of the mobile device. The calculated position and orientation information can\r\nbe used for advanced interaction metaphors like magic lenses. Moreover, for a group\r\nof experts who are analyzing the data in front of the same screen, we can provide a\r\npersonal augmented view of the visualized scene, for each user on his/her personal\r\ndevice.\r\nThe thesis discusses the design questions and the implementation steps of an\r\nAugmented Visualization System, describes the prototype setup and presents the\r\nexperimental

There is a wide range of possible applications, including virtual environments like cyber-tourism, computer games, and the entertainment industries in general, as well as urban planning and architecture, security planning and training, traffic simulation, driving guidance and telecommunications, to name but a few.\nThe research directions are spread across the disciplines of computer vision, computer graphics, image processing, photogrammetry and remote sensing, as well as architecture and the geosciences. Reconstruction is a complex problem and requires an entire pipeline of different tasks.\n\nIn this thesis we focus on processing of images of façades which is one specific subarea of urban reconstruction. The goal of our research is to provide novel algorithmic solutions for\nproblems in façade imagery processing. In particular, the contribution of this thesis is the following:\n\nFirst, we introduce a system for generation of approximate orthogonal façade images. The method is a combination of automatic and interactive tools in order to provide a convenient way to generate high-quality results.\n\nThe second problem addressed in this thesis is façade image segmentation. In particular, usually by segmentation we mean the subdivision of the façade into windows and other architectural elements. We address this topic with two different algorithms for detection of grids over the façade image.\n\nFinally, we introduce one more façade processing algorithm, this time with the goal to improve the quality of the façade appearance. The algorithm propagates visual information across the image in order to remove potential obstacles and occluding objects.\n\nThe output is intended as source for textures in urban reconstruction projects. The construction of large three-dimensional urban environments itself is beyond the scope of this thesis.

Virtual texturing works by preprocessing\r\nthe aggregate texture data into equally-sized tiles and determining the necessary tiles\r\nfor rendering before each frame.

Tile determination in view\r\nspace is examined in detail and an implementation for compressing the resulting buffer\r\nin OpenCL is presented.

To automate parts of this process, many procedural modeling methods to automatically create buildings, plants or entire cities were introduced. The main advantage of such methods compared to manual methods is the ability to create large amounts of assets using just a few parameters as input data. \r\n\r\nHowever, the main disadvantage is the difficulty to control or predict the output of such methods. Direct controllability is especially important for artists enabling them to model the output to their vision or requirements. Therefore, the main goal of this thesis is combining the direct control provided by manual methods with the power of procedural modeling.\r\n\r\nTo achieve this, several new methods and paradigms bringing direct and visual artist control to procedural generation of urban environments are contributed in this thesis. These include a method enabling a visual design process for building grammars, as well as methods providing direct artist control for architecture generation algorithms. To model whole cities, we introduce a layering system for urban layouts based on graph cut, contributing the ability to perform direct and persistent changes to a procedurally generated city. Additionally, the concept of anchored assignments is introduced, enabling direct control of parameter distributions on cities.

To allow virtual objects to seamlessly blend into the real environment, the real lighting conditions and the mutual illumination effects between real and virtual objects must be considered, while maintaining interactive frame rates (20-30fps). The most important such effects are indirect illumination and shadows cast between real and virtual objects.\n\nOur approach combines Instant Radiosity and Differential Rendering. In contrast to some previous solutions, we only need to render the scene once in order to find the mutual effects of virtual and real scenes. The dynamic real illumination is derived from the image stream of a fish-eye lens camera. We describe a new method to assign virtual point lights to multiple primary light sources, which can be real or virtual. We use imperfect shadow maps for calculating illumination from virtual point lights and have significantly improved their accuracy by taking the surface normal of a shadow caster into account. Temporal coherence is exploited to reduce flickering artifacts. Our results show that the presented method highly improves the illusion in mixed reality applications and significantly diminishes the artificial look of virtual objects superimposed onto real

Super-resolution refers to a process that increases spatial resolution by fusing information from a sequence of images acquired in one or more of several possible ways. This process is an inverse problem, one that is known to be highly ill-conditioned. Total Variation regularization is one of the well-known techniques used to deal with such problems, which has some disadvantages like staircase effect artifacts and nonphysical dissipation. To enhance the robustness of processing against these artifacts, this paper proposes a new regularization method based on the coupling of fourth order PDE and a type of newly designed shock filtering based on complex diffusion in addition to previous Total Variation. In order to have sharp corner structures like edges, this work also considers a corner shock filter. The proposed scheme is not only able to remove the jittering effect artifacts along the edge directions but also able to restrain the rounding artifacts around the corner structures and most importantly, the stabilization of the overall process is assured.

Maximum Intensity Projection (MIP) and Curved Planar Reformation (CPR) are well established and robust methods for clinical use. In case of calcified vessel walls, occlusion prevents exploring the inside of the vessels when using MIP. CPR allows to cut a single vessel along its centerline and to visualize the lumen. Extending the idea of CPR, a novel automatic method for vessel visualization is proposed. It works with multiple vessel centerlines that do not necessarily need to be connected into a tree structure. Arbitrarily complex vascular structures are rendered in the volume as point sets and optionally, occlusion halos are created around them to enhance depth perception. Vessel centerlines are automatically extracted from a volumetric data-set after performing feature extraction in a scale-space. The user is provided with the ability to control the final image and he or she can visually select the desired centerlines with visual queries by stroking with the mouse. Furthermore, a combination with the recent Maximum Intensity Difference Accumulation (MIDA) visualization technique is presented, which has the advantages of Direct Volume Rendering (DVR) such as occlusion and depth cues, but does not require an explicit transfer function specification.

Interaction on a node in the hierarchy influences\nvisual representations of 3D structures and vice versa.

However, human behavioral traits are complex and\r\ndifficult to comprehend. For this purpose, the researchers explore the anatomy\r\nand morphology of neuronal circuits of simpler species to identify their meaning\r\nand functionality. The fruit fly Drosophila melanogaster is a favorite organism\r\nin neurobiology research because it facilitates studies of complex systems on a\r\nsimple model. For this purpose, large databases of neuronal structures acquired\r\nby microscopy scans were built and adapted for computer-aided exploration and\r\nvisualization. Commodity products feature standard visualization techniques tailored\r\nfor exploration of biological structures. However, orientation in large collections\r\nof structures still poses a problem. Traditional table-view database interfaces\r\nallow filtering of items and accessing known subsets of data, but do not support\r\nselection based on spatial relationships.\r\nIn this thesis, we address this problem in the following way. We describe a system\r\nwhich facilitates visual exploration of a large collection of neuroanatomical\r\nstructures. We combined standard visualization techniques with a novel visual\r\napproach for exploration and queries. Our system provides three basic types of\r\nqueries. Path queries use an intuitive sketching interface and give access to structures\r\nlocated in the proximity of the sketched path.

EM data sets, however, suffer from bad\r\nsignal-to-noise ratio and artifacts introduced to the data set during the sectioning\r\nand digital reconstruction process of the scanned specimen. In this thesis we present\r\ntwo different approaches that generally allow noise and artifact reduction on volumetric\r\ndata sets and which can be used to increase the visual quality of direct\r\nvolume renderings (DVRs) of EM data sets. The fist approach we developed was an\r\ninteractive, on-the-fly filtering framework that allows a user to filter even very large\r\nvolume data set with resizable 3D filter-kernels. For comparison, we implemented\r\nan average, a Gaussian, and a bilateral filter. The second approach we investigated\r\nis a semi-automatic one that allows a user to select regions within a data set. Similar\r\nregions are then retrieved by our algorithm using multiresolution histograms and\r\nthe user can remove these regions from the rendering.

In the past few years, a number of rendering techniques have been developed that let the quality of the rendered images converge towards photorealism. Especially in the field of realistic scene illumination, Global Illumination (GI) techniques represent an important field of research. Previous to this work, for the first time we have applied a GI algorithm also to point clouds, which enables us to achieve realistic illumination of diffuse and glossy objects in real-time. This thesis elevates the power of visualization of this GI-Renderer to the next level. For the first time, it implements a realistic, physically based rendering of mirroring surfaces also for point clouds. Current real-time approaches addressing curved mirroring surfaces in polygon scenes either are extremely imprecise or cannot handle each arbitrary type of surface. Especially concave surfaces represent a significant difficulty for current physically based methods. Up to now, physically correct mirror reflections on complex surfaces can only be produced by offline algorithms.\r\nWe introduce a novel rendering technique called \"Screen-space curved reflections\", which enables us to produce physically correct mirror reflections on arbitrarily complex surfaces. Our method bases on the approach, for each point in the scene to find the pixel in the framebuffer that contains its reflecting surface point. This is achieved by the application of a fast 2D root finding in a new error function called \"mirror-space error function\".

Computer-based segmentation of anatomies in\r\ndata made by imaging modalities supports clinicians and speeds up their diagnosis\r\nmaking compared to doing it manually. Computed Tomography (CT) is an imaging\r\nmodality for slice-wise three dimensional reconstruction of the human body in the\r\nform of volumetric data which is especially applicable for imaging of bony structures\r\nand so for the vertebral column. Most bony structures, such as vertebrae, are\r\ncharacterised by complex shape and texture appearances which turns its segmentation\r\ninto a difficult task. Model-based segmentation approaches are promising techniques\r\nto cope with variations in form and texture of the anatomy of interest. This is\r\ndone by incorporating information about shape and texture appearance gained from\r\nan imaging modality in a model. The model can then be applied to segment the object\r\nof interest in target data, however most of the model-based approaches need a\r\nmodel intialisation for a fast and reliable segmentation of the object of interest.\r\nThis thesis was motivated by novel works on fast anatomical structure localisation\r\nwith Markov Random Fields (MRFs) and focuses on the sparse structure localisation\r\nof single vertebrae in CT scans for a subsequent model initialisation of\r\nmore sophisticated segmentation algorithms. A MRF based model of appearance,\r\nwhich employs local information in regions around anatomical landmarks and geometrical\r\ninformation through connections between adjacent landmarks, is built on\r\nvolumetric CT datasets of lumbar vertebrae. The MRF based model is built on a 6\r\nlandmark configuration in vertebra volumetric data and is additionally matched with\r\ntarget data. This is done by finding a best fit MRF matching by the Max-sum algorithm\r\namong feature points found by a decision tree based feature detection algorithm\r\ncalled probabilistic boosting tree (PBT). Anatomical landmark regions are described\r\nby vector spin-images and shape index histograms. Adjacency information\r\nis extracted by Delaunay tetrahedralisation where distances and gradient-related\r\nangles describe connections between adjacent regions. The results on single lumbar\r\nvertebra CT scans show that the MRF approach is applicable on volumetric CT\r\ndatasets with an accuracy enough for supporting more sophisticated segmentation\r\nalgorithms such as Active Appearance Models (AAMs).", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "image", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 151, "image_height": 341, "name": "major-2010-mrf-image.jpg", "type": "image/jpeg", "size": 30008, "path": "Publication:major-2010-mrf", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/major-2010-mrf-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/major-2010-mrf-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 863 ], "diploma_examina": "2010-05-11", "supervisor": [ 166, 231 ], "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "", "filetitle": "image", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 151, "image_height": 341, "name": "major-2010-mrf-image.jpg", "type": "image/jpeg", "size": 30008, "path": "Publication:major-2010-mrf", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/major-2010-mrf-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/major-2010-mrf-image:thumb{{size}}.png" }, { "description": "", "filetitle": "paper", "main_file": true, "use_in_gallery": false, "access": "public", "name": "major-2010-mrf-paper.pdf", "type": "application/pdf", "size": 4432911, "path": "Publication:major-2010-mrf", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/major-2010-mrf-paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/major-2010-mrf-paper:thumb{{size}}.png" } ], "projects_workgroups": [ "vis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2010/major-2010-mrf/", "__class": "Publication" }, { "id": "musialski-2010-tof", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Tiling of Ortho-Rectified Façade Images", "date": "2010-05", "abstract": "Typical building facades consist of regular structures such as windows arranged in a predominantly grid-like manner.

Moreover, by formal analysis of\nproduction rules we show how to efficiently update complex kinematic\nhierarchies created by the skeletons, allowing state-of-the-art interactive visual rule

computer graphics, which\nare required for rendering acceleration in the form of visibility culling, as well as for computing realistic lighting. Visibility culling, which is the main focus of this thesis, aims to provide output sensitivity by sending only visible primitives to the hardware. Regardless of the rapid development of graphics hardware, it is of crucial importance for many applications like game development or architectural design, as the demands on the hardware regarding scene complexity increase accordingly. Solving the visibility problem has been an important research topic for many years, and countless methods have been proposed. Interestingly, there are\nstill open research problems up to this day, and many algorithms are either impractical or only usable for specific scene configurations, preventing their widespread use. Visibility culling algorithms can be separated into algorithms for visibility preprocessing and online occlusion culling. Visibility computations are also required to solve complex lighting interactions in the scene, ranging from soft and hard shadows to ambient occlusion and full fledged global illumination. It is a big challenge to answer hundreds or thousands of visibility queries within a fraction\nof a second in order to reach real-time frame rates, which is one goal that we want to achieve in this thesis. The contribution of this thesis are four novel algorithms that provide solutions\nfor efficient visibility interactions in order to achieve high-quality output-sensitive real-time rendering, and are general in the sense that they work with any kind of 3D scene configuration. First we present two methods dealing with the issue of\nautomatically partitioning view space and object space into useful entities that are optimal for the subsequent visibility computations. Amazingly, this problem area was mostly ignored despite its importance, and view cells are mostly tweaked by hand in practice in order to reach optimal performance – a very time consuming task. The first algorithm specifically deals with the creation of an optimal view space partition into view cells using a cost heuristics and sparse visibility sampling. The second algorithm extends this approach to optimize both view space subdivision and object space subdivision simultaneously. Next we present a hierarchical online culling algorithm that eliminates most limitations of previous approaches, and is rendering engine friendly in the sense that it allows easy integration\nand efficient material sorting. It reduces the main problem of previous\nalgorithms – the overhead due to many costly state changes and redundant hardware occlusion queries – to a minimum, obtaining up to three times speedup over previous work. At last we present an ambient occlusion algorithm which works in screen space, and show that high-quality shading with effectively hundreds of samples per pixel is possible in real time for both static and dynamic scenes by utilizing temporal coherence to reuse samples from previous frames.", "authors_et_al": false, "substitute": null, "main_image": { "description": "temporal ssao on stanford

These properties are used to define a transfer-function space which enables the distinction of different materials. Additionally, we present a novel approach for interacting with our new transfer-function space which enables the design of transfer functions based on statistical properties.

Traditional interpretation systems involve time consuming and repetitive manual volumetric seeding for horizon growing. We present a novel system for rapidly interpreting and visualizing seismic volumetric data. First we extract horizon surface-parts by preprocessing the seismic data. Then during interaction the user can assemble in realtime the horizon parts into horizons. Traditional interpretation systems use gradient-based illumination models in the rendering of the seismic volume and polygon rendering of horizon surfaces.

Separate views and linked views are approaches to cope with complexity, but are limited, e.g., concerning scalability.

Every visualization algorithm is a unique point in A-space. Integrated visualizations can be interpreted as an “interpolation” between known algorithms. The void between algorithms can be considered as a visualization opportunity where a new point in A-space can be reconstructed and new integrated visualizations can be created.

The last survey that encompassed shadow mapping approaches, but was mainly focused on soft shadow generation, dates back to 2003~cite{HLHS03} and the last survey for general shadow generation dates back to 1990~cite{Woo:1990:SSA}. No survey that describes all the advances made in hard shadow map generation in recent years exists.\n\nOn the other hand, shadow mapping is widely used in the game industry, in production, and in many other applications, and it is the basis of many soft shadow algorithms. Due to the abundance of articles on the topic, it has become very hard for practioners and researchers to select a suitable shadow algorithm, and therefore many applications miss out on the latest high-quality shadow generation approaches. \n\n%Real-time research was always tempted to bring global lighting techniques into the real-time domain. One of the most popular adaptations in this respect are hard shadows. It is therefore not surprising that real-time hard shadow generation has been one of the most active areas in research in recent years. But what is surprising is that the last state-of-the-art report that encompassed this field dates back to 1990~cite{Woo:1990:SSA}, were only the beginnings of this field were explored. \n\nThe goal of this survey is to rectify this situation by providing a detailed overview of this field.

By taking advantage of TC, we can save redundant computation and improve the performance of many rendering tasks significantly with only a marginal decrease in quality. This not only allows us to incorporate more computationally intensive shading effects to existing applications, but also offers exciting opportunities of extending high-end graphics applications to reach lower-spec consumer-level hardware.\n\nThis course aims to introduce participants to the concepts of TC, and provide them the working practical and theoretical knowledge to exploit TC in a variety of shading tasks. It begins with an introduction of the general notion of TC in rendering, as well as an overview of the recent developments in this field. Then it focuses on a key data structure - the reverse reprojection cache, which is the foundation of many applications. The course proceeds with a number of extensions of the basic algorithm for assisting in multi-pass shading effects, shader antialiasing, casting shadows and global-illumination effects. Finally, several more general coherence topics beyond pixel reuse are introduced, including visibility culling optimization and object-space global-illumination approximations. For all the major techniques and applications covered, implementation and practical issues involved in development are addressed in detail.\n\nIn general, we emphasize \"know how\" and the guidelines related to algorithm choices. After the course, participants are encouraged to find and utilize TC in their own applications and rapidly adapt existing algorithms to meet their requirements.", "authors_et_al": false, "substitute":

The continuous improvements in magnetic resonance imaging (MRI) technology facilitate more accurate diagnoses by providing increasingly more detailed information on the viability, functioning, perfusion, and anatomy of a patient’s heart. The talk covers several novel techniques that realize multi-modal visualizations of a patient’s heart to assist in the diagnosis of coronary artery disease . A volumetric bull’s eye offers a more comprehensive view on the viability of a patient’s heart by providing detailed information on the transmurality of scar while not suffering from discontinuities. Anatomical context is often lost due to abstract representations of data, or may be scarce due to the nature of the scanning protocol. Several techniques to restore the relation to anatomy are presented. The primary coronary arteries are segmented in a whole heart scan and mapped onto a volumetric bull’s eye plot, adding anatomical context to an abstract representation. Similarly, segmented late enhancement data are rendered along with a three-dimensional segmentation of the patient-specific myocardial and coronary anatomy. Additionally, coronary supply territories are computed from patient-specific data as an improvement over models based on population averages. Information on the perfusion of the myocardium provided by MRI is typically of fairly low resolution. Using high-resolution anatomical data, an approach to visualize simulated myocardial perfusion is presented, taking full advantage of the detailed information on perfusion. Finally, a truly comprehensive visualization of a cardiac MRI exam is explored by combining whole heart, late enhancement, functional, and perfusion scans in a single visualization.\r\n", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 166 ], "date_from": "2010-05-21", "event": "MedViz seminar", "location": "University of Bergen", "research_areas": [], "keywords": [], "weblinks": [], "files": [], "projects_workgroups": [ "vis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2010/Groeller-2010-CVC/", "__class": "Publication" }, { "id": "groeller-2010-How", "type_id": "misc", "tu_id": null, "repositum_id": null, "title": "How To Do Research", "date": "2010", "abstract": "", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 166 ], "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "Slides", "filetitle": "Slides", "main_file": false, "use_in_gallery": false, "access": "public", "name": "groeller-2010-How-Slides.pptx", "type": "application/zip", "size": 19215705, "path": "Publication:groeller-2010-How", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/groeller-2010-How/groeller-2010-How-Slides.pptx", "thumb_image_sizes": [] } ], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/2010/groeller-2010-How/", "__class": "Publication" }, { "id": "Groeller-2010-IFI", "type_id": "talk", "tu_id": null, "repositum_id": null, "title": "Illustrative Visualization", "date": "2010", "abstract": "Illustrations play a major role in the education process. 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. One of the key concepts for creating an expressive illustration is abstraction. Abstraction introduces a distortion between the visualization and the underlying model according to the communicative intent of the illustration. Inspired by observations from hand-made illustrations, similar techniques for the generation of rendered images have been developed. These techniques work on different levels: low level abstraction techniques (stylized depiction methods) deal with how objects should be presented, while high level abstraction techniques (smart visibility approaches) are concerned with what should be visible and recognizable. We review several existing approaches from both categories and describe concepts used in the design of a system for creating interactive illustrations directly from volumetric data. A fully dynamic three-dimensional illustration environment is discussed which directly operates on volume data. Single images have the aesthetic appeal of traditional illustrations, but can be interactively altered and explored. Furthermore, we discuss several illustrative concepts like style transfer functions, exploded views, semantic layers, and illustration-inspired integrated views.

Separate views and linked views are approaches to cope with complexity, but are limited, e.g., concerning scalability.\r\nThis talk will concentrate rather on integrated views as inspired by traditional illustrations. The concept of A-space is presented. It is the “space” where visualization algorithms reside. Every visualization algorithm\r\nis a unique point in A-space. Integrated visualizations can be interpreted as an “interpolation” between known algorithms. The void between algorithms can be considered as a visualization opportunity where a new point in A-space can be reconstructed and new integrated visualizations can be created.

A DCI consist of curves with colors defined on either side.

It consists of a robust rasterization technique to transform the algebraic curves to the discrete image domain, and a variable stencil size diffusion solver that solves the minimal surface problem. The solver is proven to converge to the right solution, it is at least as fast as commonly used multigrid solvers, but \nmuch simpler to implement, works for arbitrary image resolutions, as well as 8 bit data.\nThe second part of the talk extends the application of diffusion curves to render high quality surface details on 3D objects. The first extension is a view dependent warping technique that dynamically allocates more texture memory for details close to the observer. The second extension is a dynamic feature embedding technique that retains crisp, anti-aliased curve details even in extreme closeups.

rendered 3D layers\ntailored to the needs of scientific illustration. Currently, traditional scientific illustrations are produced\nin a series of composition stages, combining different pictorial elements using 2D digital layering. Our\napproach extends the layer metaphor into 3D without giving up the advantages of 2D methods. The\nnew compositing approach allows for effects such as selective transparency, occlusion overrides, and\nsoft depth buffering. Furthermore, we show how common manipulation techniques such as masking\ncan be integrated into this concept. These tools behave just like in 2D, but their influence extends\nbeyond a single viewpoint. Since the presented approach makes no assumptions about the underlying\nrendering algorithms, layers can be generated based on polygonal geometry, volumetric data, pointbased\nrepresentations, or others. Our implementation exploits current graphics hardware and permits\nreal-time interaction and rendering.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle":
