We propose a computational design framework for pose-driven automated generation of body-supports which are optimized for comfort of sitting. Given a human body in a specified pose as input, our method computes an approximate pressure distribution that also takes frictional forces and body torques into consideration which serves as an objective measure of comfort. Utilizing this information to find out where the body needs to be supported in order to maintain comfort of sitting, our algorithm can create a supporting mesh suited for a person in that specific pose. This is done in an automated fitting process, using a template model capable of supporting a large variety of sitting poses.

In this paper we propose a novel approach for the design of architectural floorplans by integrating structural layout analysis directly into the planning process. In order to achieve this, we introduce a planning tool which interactively enforces checks for structural stability of the current design, and which on demand proposes how to stabilize it if necessary. Technically, our solution contains an interactive architectural modeling framework as well as a constrained optimization module where both are based on respective architectural rules. Using our tool, an architect can predict already in a very early planning stage which designs are structurally sound such that later changes due to stability reasons can be prevented.

Since the constraints as well as the objective functional can easily be adjusted to specific application requirements, our method provides a flexible and powerful tool for shape optimization. We use manifold harmonics to derive a reduced-order formulation of the optimization problem, which guarantees a smooth offset surface and speeds up the computation independently from the input mesh resolution without affecting the quality of the result. The constrained optimization problem can be solved in a numerically robust manner with commodity solvers. Furthermore, the method allows simultaneously optimizing an inner and an outer offset in order to increase the degrees of freedom. We demonstrate our method in a number of examples where we control the physical mass properties of rigid objects for the purpose of 3d printing.

Common procedural approaches, such as shape grammars, assume that building façades are organized in a tree structure, while in practice this is often not the case. Consequently, the complexity of their layout description becomes unmanageable for interactive editing. In contrast, we obtain a façade by composing multiple overlapping layers, where each layer contains a single rectilinear grid of façade elements described by two simple generator patterns. This way, the design process becomes more intuitive and the editing effort for complex layouts is significantly reduced. To achieve this, we present a method for the automated merging of different layers in the form of a mixed discrete and continuous optimization problem. Finally, we provide several modeling examples and a comparison to shape grammars in order to highlight the advantages of our method when designing realistic building façades.

On the other hand, due to the growing capabilities of personal digital fabrication technology and its spread into offices and homes, 3d models are increasingly entering the physical world. Therefore, the physical properties of 3d models come into focus. For example, 3d-printed models should be able to stand balanced in a desired pose without toppling over, or should react in certain ways when external forces are applied, like spinning the object. It is thus desirable to have methods that allow the user to specify the intended physical properties of an object in addition to its 3d geometry, and which automatically take these properties into account when generating a specification for a 3d printer.\r\n\r\nIn this talk I will give an introduction to such computational design problems and introduce our novel method for shape optimization based on offset surfaces.\r\n\r\n\r\nLink: http://www.vrvis.at/research/events/vrvisforum/vrvisforum-123-29.10.2015", "authors_et_al": false, "substitute": null, "main_image": { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1600, "image_height": 900, "name": "musialski-2015-vrvis-thumbnail.png", "type": "image/png", "size": 96358, "path": "Publication:musialski-2015-vrvis", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/musialski-2015-vrvis-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/musialski-2015-vrvis-thumbnail:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 844 ], "date_from": "2015-10-29", "date_to": "2015-10-29", "event": "VRVisForum #123", "location": "VRVis, Techgate Vienna, Austria", "research_areas": [], "keywords": [ "shape optimization", "geometry processing", "digital fabrication" ], "weblinks": [], "files": [ { "description": "slides", "filetitle": "slides", "main_file": false, "use_in_gallery": false, "access": "public", "name": "musialski-2015-vrvis-slides.pdf", "type": "application/pdf", "size": 2945919, "path": "Publication:musialski-2015-vrvis", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/musialski-2015-vrvis-slides.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/musialski-2015-vrvis-slides:thumb{{size}}.png" }, { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1600, "image_height": 900, "name": "musialski-2015-vrvis-thumbnail.png", "type": "image/png", "size": 96358, "path": "Publication:musialski-2015-vrvis", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/musialski-2015-vrvis-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/musialski-2015-vrvis-thumbnail:thumb{{size}}.png" } ], "projects_workgroups": [ "MAKE-IT-FAB" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-vrvis/", "__class": "Publication" }, { "id": "musialski-2015-pixel", "type_id": "talk", "tu_id": null, "repositum_id": null, "title": "Computational Design for Consumer-Level Fabrication", "date": "2015", "abstract": "Digital fabrication is currently a rapidly emerging field in several science and engineering fields. Especially the technique of additive manufacturing (AM), commonly referred to as 3d printing, is a fast growing area. While this technology is in essence not new, the recent expiration of key patents for 3d-printing technology led to a break-through, which already also arrived at the consumer-level 3d-printers market. This development brings about novel requirements on digital model design. Traditional fields used to deal with digital manufacturing, like rapid prototyping, material sciences, or industrial engineering learned to deal with existing CAD-software in order to create digital content. However, the expansion of the digital fabrication technology into everybody’s homes and offices brings about the demand for novel paradigms of consumer-level computational design. This novel personal fabrication aims at bridging the gap between the still advancing digital domain and the “good old” physical world. In this talk I will give an overview of current development of such computational design in the field of computer graphics and provide details on an example application. \r\n\r\nLink: http://www.pixelvienna.com/10/event/talks#musialski", "authors_et_al": false, "substitute": null, "main_image": { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1648, "image_height": 927, "name": "musialski-2015-pixel-thumbnail.png", "type": "image/png", "size": 101955, "path": "Publication:musialski-2015-pixel", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/musialski-2015-pixel-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/musialski-2015-pixel-thumbnail:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 844 ], "date_from": "2015-11-01", "date_to": "2015-11-01", "event": "PIXEL X - Annual Austrian Computer Graphics and Animation Conference, Vienna, Austria", "location": "PIXEL X, TU Wien, Karlsplatz 1, Vienna, Austria", "research_areas": [], "keywords": [ "digital fabrication", "geometry processing", "shape optimization", "computational design" ], "weblinks": [], "files": [ { "description": "slides", "filetitle": "slides", "main_file": false, "use_in_gallery": false, "access": "public", "name": "musialski-2015-pixel-slides.pdf", "type": "application/pdf", "size": 2432505, "path": "Publication:musialski-2015-pixel", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/musialski-2015-pixel-slides.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/musialski-2015-pixel-slides:thumb{{size}}.png" }, { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1648, "image_height": 927, "name": "musialski-2015-pixel-thumbnail.png", "type": "image/png", "size": 101955, "path": "Publication:musialski-2015-pixel", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/musialski-2015-pixel-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/musialski-2015-pixel-thumbnail:thumb{{size}}.png" } ], "projects_workgroups": [ "MAKE-IT-FAB" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-pixel/", "__class": "Publication" }, { "id": "musialski-2015-ista", "type_id": "talk", "tu_id": null, "repositum_id": null, "title": "Reduced-Order Shape Optimization Using Offset Surfaces", "date": "2015", "abstract": "Given the 2-manifold surface of a 3d object, we propose a novel method for the computation of an offset surface with varying thickness such that the solid volume between the surface and its offset satisfies a set of prescribed constraints and at the same time minimizes a given objective functional. Since the constraints as well as the objective functional can easily be adjusted to specific application requirements, our method provides a flexible and powerful tool for shape optimization. We use manifold harmonics to derive a reduced-order formulation of the optimization problem, which guarantees a smooth offset surface and speeds up the computation independently from the input mesh resolution without affecting the quality of the result. The constrained optimization problem can be solved in a numerically robust manner with commodity solvers. Furthermore, the method allows simultaneously optimizing an inner and an outer offset in order to increase the degrees of freedom. We demonstrate our method in a number of examples where we control the physical mass properties of rigid objects for the purpose of 3d printing. \r\n\r\n\r\nLink: https://ist.ac.at/events/symposia-conferences/2015/siggraph-nano-ist-austria/date/433/", "authors_et_al": false, "substitute": null, "main_image": { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1600, "image_height": 900, "name": "musialski-2015-ista-thumbnail.png", "type": "image/png", "size": 138609, "path": "Publication:musialski-2015-ista", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/musialski-2015-ista-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/musialski-2015-ista-thumbnail:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 844 ], "date_from": "2015-06-24", "date_to": "2015-06-24", "event": "SIGGRAPH Nano @ Institute of Science and Technology (IST), Austria", "location": "Institute of Science and Technology (IST), Austria", "research_areas": [], "keywords": [ "geometry processing", "digital fabrication", "shape optimization" ], "weblinks": [], "files": [ { "description": "slides", "filetitle": "slides", "main_file": false, "use_in_gallery": false, "access": "public", "name": "musialski-2015-ista-slides.pdf", "type": "application/pdf", "size": 4213999, "path": "Publication:musialski-2015-ista", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/musialski-2015-ista-slides.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/musialski-2015-ista-slides:thumb{{size}}.png" }, { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1600, "image_height": 900, "name": "musialski-2015-ista-thumbnail.png", "type": "image/png", "size": 138609, "path": "Publication:musialski-2015-ista", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/musialski-2015-ista-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/musialski-2015-ista-thumbnail:thumb{{size}}.png" } ], "projects_workgroups": [ "MAKE-IT-FAB" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2015/musialski-2015-ista/", "__class": "Publication" }, { "id": "fan-2014-scfl", "type_id": "journalpaper", "tu_id": null, "repositum_id": null, "title": "Structure Completion for Facade Layouts", "date": "2014-11", "abstract": "We present a method to complete missing structures in facade layouts.

Our approach is based on the minimization of an energy function that combines multiple goals: positioning of the lenses as close as possible to the corresponding region shown in an overview map, keeping the number of lenses low, and an efficient numbering of the lenses.\nThe second contribution is a route-aware simplification of the graph of streets used for traveling between the points of interest (POIs). This is done by reducing the graph consisting of all shortest paths through the minimization of an energy function. The output is a subset of street segments that enable traveling between all the POIs without considerable detours, while at the same time guaranteeing a clutter-free visualization.\n\nVideo:

data-sets. Our input is a triangle mesh and a set of calibrated and registered photographs. Our system performs the actual mapping of the photos to the mesh for high-quality reconstructions, which is a task referred to as the labeling problem. Another problem of such mappings are seams that arise on junctions between triangles that contain information from different photos. These are are approached with blending methods, referred to as leveling. We address both problems and introduce a novel labeling approach based on occlusion detection using depth maps that prevents texturing of parts of the model with images that do not contain the expected region. Moreover, we propose an improved approach for seam-leveling that penalizes too large values and helps to keep the resulting colors in a valid range. For high-performance visualization of the 3D models with a huge amount of textures, we make use of virtual texturing, and present an application that generates the needed texture atlas in significantly less time than existing scripts. Finally, we show how the mentioned components are integrated into a visualization application for digitized archaeological site.", "authors_et_al": false, "substitute": null, "main_image": { "description": "thumb", "filetitle": "thumb", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1024, "image_height": 652, "name": "birsak-2013-sta-thumb.jpg", "type": "image/jpeg", "size": 123764, "path": "Publication:birsak-2013-sta", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-thumb.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-thumb:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 836, 844, 865, 193 ], "booktitle": "Digital Heritage International Congress (DigitalHeritage), 2013", "date_from": "2013-10-28", "date_to": "2013-11-01", "isbn": "978-1-4799-3168-2 ", "lecturer": [ 836 ], "location": "Marseille, France", "note": "DOI: 10.1109/DigitalHeritage.2013.6743749", "pages_from": "265", "pages_to": "272 ", "publisher": "IEEE", "research_areas": [ "Rendering" ], "keywords": [ "digital cultural heritage", "out-of-core real-time rendering", "seamless texturing", "virtual texturing" ], "weblinks": [], "files": [ { "description": "paper draft", "filetitle": "preprint", "main_file": true, "use_in_gallery": false, "access": "public", "name": "birsak-2013-sta-preprint.pdf", "type": "application/pdf", "size": 2939089, "path": "Publication:birsak-2013-sta", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-preprint.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-preprint:thumb{{size}}.png" }, { "description": "thumb", "filetitle": "thumb", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1024, "image_height": 652, "name": "birsak-2013-sta-thumb.jpg", "type": "image/jpeg", "size": 123764, "path": "Publication:birsak-2013-sta", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-thumb.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-thumb:thumb{{size}}.png" }, { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1282, "image_height": 712, "name": "birsak-2013-sta-thumbnail.jpg", "type": "image/jpeg", "size": 184340, "path": "Publication:birsak-2013-sta", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-thumbnail.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/birsak-2013-sta-thumbnail:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2013/birsak-2013-sta/", "__class": "Publication" }, { "id": "musialski-2013-surcgf", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": null, "title": "A Survey of Urban Reconstruction", "date": "2013-09", "abstract": "This paper provides a comprehensive overview of urban reconstruction.

To overcome this difficulty a novel modeling paradigm has been introduced: it is commonly referred to as inverse procedural modeling, and its goal is to generate compact procedural descriptions of existing models---in the best case in an automatic manner as possible. These compact procedural representations can be used as a source for the synthesis of identical or similar objects, applied in various simulations and other studies of urban environments.

Our methodology is built on recent studies about matrix completion using the matrix trace norm. The contribution of our paper is to extend the matrix case to the tensor case by proposing the first definition of the trace norm for tensors and then by building a working algorithm. First, we propose a definition for the tensor trace norm, that generalizes the established definition of the matrix trace norm. Second, similar to matrix completion, the tensor completion is formulated as a convex optimization problem. We developed three algorithms: SiLRTC, FaLRTC, and HaLRTC. The SiLRTC algorithm is simple to implement and employs a relaxation technique to separate the dependant relationships and uses the block coordinate descent (BCD) method to achieve a globally optimal solution; The FaLRTC algorithm utilizes a smoothing scheme to transform the original nonsmooth problem into a smooth one; The HaLRTC algorithm applies the alternating direction method of multipliers (ADMM) to our problem. Our experiments show potential applications of our algorithms and the quantitative evaluation indicates that our methods are more accurate and robust than heuristic approaches.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 200, "image_height": 90, "name": "liu-2012-tcvd-image.jpg", "type": "image/jpeg", "size": 19710, "path": "Publication:liu-2012-tcvd", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 985, 844, 194, 986 ], "issn": "0162-8828", "journal": "IEEE Transactions on Pattern Analysis & Machine Intelligence (PAMI)", "number": "1", "pages_from": "208", "pages_to": "220", "volume": "35", "research_areas": [], "keywords": [ "matrix completion", "trace norm", "tensor completion" ], "weblinks": [ { "href": "http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6138863", "caption": null, "description": null, "main_file": 0 } ], "files": [ { "description": "", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 200, "image_height": 90, "name": "liu-2012-tcvd-image.jpg", "type": "image/jpeg", "size": 19710, "path": "Publication:liu-2012-tcvd", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-image:thumb{{size}}.png" }, { "description": "", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 653, "image_height": 429, "name": "liu-2012-tcvd-image.png", "type": "image/png", "size": 352833, "path": "Publication:liu-2012-tcvd", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-image:thumb{{size}}.png" }, { "description": "preprint", "filetitle": "preprint", "main_file": false, "use_in_gallery": false, "access": "public", "name": "liu-2012-tcvd-preprint.pdf", "type": "application/pdf", "size": 2140279, "path": "Publication:liu-2012-tcvd", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-preprint.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/liu-2012-tcvd-preprint:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2012/liu-2012-tcvd/", "__class": "Publication" }, { "id": "musialski_2012_aachen", "type_id": "talk", "tu_id": null, "repositum_id": null, "title": "Image-Based Approaches for Facade Reconstruction", "date": "2012", "abstract": "Modeling and reconstruction of urban environments is currently the subject of intensive\r\nresearch.

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.

The output is intended as source for textures in urban reconstruction projects.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "image", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 221, "image_height": 89, "name": "musialski-2009-sbfr-image.jpg", "type": "image/jpeg", "size": 20422, "path": "Publication:musialski-2009-sbfr", "url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/musialski-2009-sbfr-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/musialski-2009-sbfr-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 844, 194, 846, 228, 190 ], "booktitle": "Vision, Modeling, and Visualization Workshop 2009", "date_from": "2009-11-16", "date_to": "2009-11-18", "editor": "Marcus Magnor, Bodo Rosenhahn, Holger Theisel ", "isbn": "978-3980487481", "lecturer": [ 844 ], "location": "Braunschweig", "research_areas": [ "Modeling" ], "keywords": [], "weblinks": [], "files": [ { "description": null, "filetitle": "image", "main_file": true, "use_in_gallery": false, "access": "public", "image_width": 221, "image_height": 89, "name": "musialski-2009-sbfr-image.jpg", "type": "image/jpeg", "size": 20422, "path": "Publication:musialski-2009-sbfr", "url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/musialski-2009-sbfr-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/musialski-2009-sbfr-image:thumb{{size}}.png" }, { "description": null, "filetitle": "paper", "main_file": true, "use_in_gallery": false, "access": "public", "name": "musialski-2009-sbfr-paper.pdf", "type": "application/pdf", "size": 6476585, "path": "Publication:musialski-2009-sbfr", "url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/musialski-2009-sbfr-paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/musialski-2009-sbfr-paper:thumb{{size}}.png" } ], "projects_workgroups": [ "VRVis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2009/musialski-2009-sbfr/", "__class": "Publication" } ]
