Our framework is suitable for helping users explore their environment.\nFirst, given a starting point and a maximum route length, the system retrieves nearby points of interest (POIs). Second, we automatically compute an attractive walking path through the environment trying to pass by as many highly ranked POIs as possible. Third, we automatically compute a route visualization that shows the current user position, POI locations via pins, and detail lenses for more information about the POIs. The visualization is an animation of an orthographic map view that follows the current user position. We propose an optimization based on a binary integer program (BIP) that models multiple requirements for an effective placement of detail lenses. We show that our path computation method outperforms recently proposed methods and we evaluate the overall impact of our framework in two user studies.", "authors_et_al": false, "substitute": null, "main_image": { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 2002, "image_height": 1246, "name": "birsak-2017-dpe-thumbnail.png", "type": "image/png", "size": 1540567, "path": "Publication:birsak-2017-dpe", "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-thumbnail:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 836, 844, 194, 193 ], "doi": "10.1109/TVCG.2017.2690294", "issn": "1077-2626", "journal": "IEEE Transactions on Visualization and Computer Graphics", "number": "5", "pages_from": "1784", "pages_to": "1798", "protocol": "null", "volume": "24", "research_areas": [ "InfoVis" ], "keywords": [], "weblinks": [], "files": [ { "description": "overview image", "filetitle": "overview", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 2229, "image_height": 2762, "name": "birsak-2017-dpe-overview.png", "type": "image/png", "size": 3708886, "path": "Publication:birsak-2017-dpe", "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-overview.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-overview:thumb{{size}}.png" }, { "description": null, "filetitle": "preprint", "main_file": true, "use_in_gallery": false, "access": "public", "name": "birsak-2017-dpe-preprint.pdf", "type": "application/pdf", "size": 39449554, "path": "Publication:birsak-2017-dpe", "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-preprint.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-preprint:thumb{{size}}.png" }, { "description": null, "filetitle": "supplementary", "main_file": false, "use_in_gallery": false, "access": "public", "name": "birsak-2017-dpe-supplementary.pdf", "type": "application/pdf", "size": 26746193, "path": "Publication:birsak-2017-dpe", "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-supplementary.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-supplementary:thumb{{size}}.png" }, { "description": "thumbnail", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 2002, "image_height": 1246, "name": "birsak-2017-dpe-thumbnail.png", "type": "image/png", "size": 1540567, "path": "Publication:birsak-2017-dpe", "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-thumbnail.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-thumbnail:thumb{{size}}.png" }, { "description": null, "filetitle": "video", "main_file": false, "use_in_gallery": false, "access": "public", "name": "birsak-2017-dpe-video.mp4", "type": "video/mp4", "size": 45077025, "path": "Publication:birsak-2017-dpe", "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-video.mp4", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-video:thumb{{size}}.png", "video_mp4": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/birsak-2017-dpe-video:video.mp4" } ], "projects_workgroups": [ "Photo-Guide", "MAKE-IT-FAB" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2018/birsak-2017-dpe/", "__class": "Publication" }, { "id": "kendlbacher-2016", "type_id": "bachelorthesis", "tu_id": null, "repositum_id": null, "title": "Introduction Of OpenStreetMap For The Automatic Generation Of Destination Maps", "date": "2016", "abstract": "A destination map allows all travelers, within the given region of interest, to reach\nthe same destination, no matter where exactly they start their journey at.

The intuitive procedure just uses specific adjustable parameters for the lens of a camera to generate the desired effect in real-time. Using nothing but the depth information of a scene, the depth of field can be computed.\r\nThe so called circles of confusion are the representing value of the blur rate for objects that are out of focus. Depending on the distance between the focal plane and the current pixel, an expansion takes place because of the redirecting nature of a lens. The following required information is retrieved using an intensity distribution function.\r\nTo avoid intensity leakage and provide a full opaque picture, the entire effect is done discrete on the screen space. This prevents subsampling and enables almost correct alpha value normalization.\r\nAs stated before, an intensity distribution function is required, but in a discrete form. This is an addition to the paper, where that function is preprocessed in the application and provided for the shader directly. A high resolution texture of the desired intensity distribution function is provided as input to a shader program that renders multiple discrete versions. Another further addition prepares the texture by normalization, consuming more memory, but saving lots of time during computation.\r\nThe last part of this paper includes a defocused highlights implementation, where a tone-mapping is applied to mimic them. In general, the luminance of a pixel is computed by a simple formula, summing up the three colors with adjustment factors. Depending on this value and some parameters, the color is adjusted where bright regions are enhanced to construct this effect.\r\nThis thesis implements and extends this work and is used to test its performance after seven years when it was published. Using different configurations for the effect, the provided stable framerates of the results are used as metric for benchmarking.\r\n", "authors_et_al": false, "substitute": null, "main_image": { "description": "image", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1026, "image_height": 568, "name": "Kollmann-2015-DoF-image.png", "type": "image/png", "size": 181249, "path": "Publication:Kollmann-2015-DoF", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/Kollmann-2015-DoF-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/Kollmann-2015-DoF-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 1212 ], "date_end": "2015-09-15", "date_start": "2014-09-15", "matrikelnr": "1126633", "supervisor": [ 844, 779, 193 ], "research_areas": [], "keywords": [ "depth-of-field", "deferred rendering", "real-time rendering" ], "weblinks": [], "files": [ { "description": "image", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1026, "image_height": 568, "name": "Kollmann-2015-DoF-image.png", "type": "image/png", "size": 181249, "path": "Publication:Kollmann-2015-DoF", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/Kollmann-2015-DoF-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/Kollmann-2015-DoF-image:thumb{{size}}.png" }, { "description": "thesis", "filetitle": "thesis", "main_file": true, "use_in_gallery": false, "access": "public", "name": "Kollmann-2015-DoF-thesis.pdf", "type": "application/pdf", "size": 3004539, "path": "Publication:Kollmann-2015-DoF", "url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/Kollmann-2015-DoF-thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/Kollmann-2015-DoF-thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2015/Kollmann-2015-DoF/", "__class": "Publication" }, { "id": "Adorjan-2015", "type_id": "masterthesis", "tu_id": null, "repositum_id": null, "title": "The OpenSFM Database", "date": "2015", "abstract": "Besides using high-cost laser scanning equipment to capture large point clouds for topographical or architectural purposes, nowadays other, more affordable approaches exist. Structure-from-motion (SfM) in combination with multi-view stereo (MVS) is such a low-cost photogrammetric method used to generate large point datasets. It refers to the process of estimating three-dimensional structures out of two-dimensional image sequences. These sequences can even be captured with conventional consumer-grade digital cameras.\n\nIn our work we aim to a establish a free and fully accessible structure-from-motion system, based on the idea of collaborative projects like OpenStreetMap. Our client-server system, called OpenSfM, consists of a web front-end which lets the user explore, upload and edit SfM-datasets and a back-end that answers client requests and processes the uploaded data and stores it in a database.\n\nThe front-end is a virtual tourism client which allows the exploration of georeferenced point clouds together with their corresponding SfM-data like camera parameters and photos. The information is rendered in the context of an interactive virtual globe. An upload functionality makes it possible to integrate new SfM-datasets into the system and improve or extend existing datasets by adding images that fill missing areas of the affected point cloud. Furthermore, an edit mode allows the correction of georeferencing or reconstruction errors.\n\nOn the other side the back-end evaluates the uploaded information and generates georeferenced point datasets using a state-of-the-art SfM engine and the GPS data stored in the uploaded images. The generated point clouds are preprocessed, such that they can be used by the front-end’s point cloud renderer. After that, they are stored together with the uploaded images and SfM parameters in the underlying database.\n\nOn the whole, our system allows the gathering of SfM-datasets that represent different sights or landmarks, but also just locally famous buildings, placed all over the world.

While today the rendering part is highly sophisticated and automated, 3d modeling is still a very challenging task due to the steep learning curve and the amount of work time required. Although there are a lot of free model databases available in the internet, this models are in general not perfectly suited to the customers needs and have to be adapted.\n\nStructure-aware shape manipulation deals with the complexity of creating variations, or adapting a given input model while retaining global features like symmetry and connectivity. The majority of existing algorithms only try to preserve structural features, or have very limited support for adapting the overall structure of the model to changes made by the user. The lack of complex structural changes in the model, for example allowing a wheel to change the number of strokes, limits the number of possible variations this algorithms can generate. \n\nThe aim of this thesis is to exploit the possibilities of using curves and curve spaces to find a better representation of the input model, allowing for complex structural adaptions. In addition to this the usefulness of a multi-layered graphs to represent the model and it's constraints should be investigated.\n", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "image", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 682, "image_height": 441, "name": "steiner-2014-da-image.png", "type": "image/png", "size": 185956, "path": "Publication:steiner-2014-da", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 1120 ], "date_end": "2014", "date_start": "2014-01-13", "matrikelnr": "0825391", "supervisor": [ 193, 844 ], "research_areas": [ "Modeling" ], "keywords": [ " structure-aware model manipulation", "modelling", "cg" ], "weblinks": [], "files": [ { "description": null, "filetitle": "image", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 682, "image_height": 441, "name": "steiner-2014-da-image.png", "type": "image/png", "size": 185956, "path": "Publication:steiner-2014-da", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-image:thumb{{size}}.png" }, { "description": null, "filetitle": "poster", "main_file": true, "use_in_gallery": true, "access": "public", "name": "steiner-2014-da-poster.pdf", "type": "application/pdf", "size": 1661123, "path": "Publication:steiner-2014-da", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-poster.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-poster:thumb{{size}}.png" }, { "description": null, "filetitle": "thesis", "main_file": true, "use_in_gallery": true, "access": "public", "name": "steiner-2014-da-thesis.pdf", "type": "application/pdf", "size": 12027877, "path": "Publication:steiner-2014-da", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/steiner-2014-da-thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2014/steiner-2014-da/", "__class": "Publication" }, { "id": "charpenay-2014-sgn", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Sampling Gabor Noise in the Spatial Domain", "date": "2014-05", "abstract": "Gabor noise is a powerful technique for procedural texture generation.

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, a method is presented\r\nthat can generate six-sided cube maps out of a spherical panorama.", "authors_et_al": false, "substitute": null, "main_image": { "description": "image", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 812, "image_height": 440, "name": "schaukowitsch-2013-fls-image.jpg", "type": "image/jpeg", "size": 129904, "path": "Publication:schaukowitsch-2013-fls", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/schaukowitsch-2013-fls-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/schaukowitsch-2013-fls-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 1093 ], "date_start": "2013-04-03", "matrikelnr": "0927289", "supervisor": [ 836, 844 ], "research_areas": [], "keywords": [ "multi-view image processing", "panorama imaging", "image compositing" ], "weblinks": [], "files": [ { "description": "image", "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 812, "image_height": 440, "name": "schaukowitsch-2013-fls-image.jpg", "type": "image/jpeg", "size": 129904, "path": "Publication:schaukowitsch-2013-fls", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/schaukowitsch-2013-fls-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/schaukowitsch-2013-fls-image:thumb{{size}}.png" }, { "description": "thesis", "filetitle": "Thesis", "main_file": true, "use_in_gallery": false, "access": "public", "name": "schaukowitsch-2013-fls-Thesis.pdf", "type": "application/pdf", "size": 12865915, "path": "Publication:schaukowitsch-2013-fls", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/schaukowitsch-2013-fls-Thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/schaukowitsch-2013-fls-Thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2013/schaukowitsch-2013-fls/", "__class": "Publication" }, { "id": "sperl-2013-BA", "type_id": "bachelorthesis", "tu_id": null, "repositum_id": null, "title": "Procedural Textures for Architectural Models ", "date": "2013-09", "abstract": "Texturing plays an extremely important role in computer graphics. They may for example give flat objects colour patterns and depth or roughness. However it is often difficult to find or create fitting textures for a geometry or surface. Creating textures by hand can prove extremely difficult as problems with seams or distortion may occur, which make the texture look unrealistic. In order to counter these problems many different kinds of texture synthesis have been developed among which procedural textures hold an important position.\n\nThe types of texture synthesis methods vary from example-based synthesis to procedural noise, cellular textures and more, which can produce a wide array of different results.\n\nThe aim of this paper is to introduce the reader into related topics of texture synthesis and to introduce a method for generating cellular brick pattern textures that represent brick bonds that are used in real architecture taking correct handling of wall and window borders into consideration. The method uses few parameters to control the synthesis process. In addition a method for generating random stone patterns is introduced.

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.

modeling technique and has already been used extensively in CGI for motion pictures or computer games. An artist creates a coarse polygon mesh, that is computationally converted into a high-quality smooth surface. Due to the recursive nature of the subdivision algorithm and the large number of polygons, that are generated during the mesh-refinement, it is not well suited for realtime-environments. There exist several approaches\r\nto generate a Catmull-Clark subdivision surface which use current GPU technologies to overcome these issues.\r\n\r\nIn this thesis, we use Compute Shaders for subdivision and a Cubic Bezier Patch which takes advantage of the tessellation pipeline to get an optimized algorithm without the loss of visual quality.

The goal of this master thesis is the research on methods for creating simple geometry out of such initial data. In the process of the work a modeling tool will be implemented, which enables users to integrate polyhedral primitives in a 3D point dataset.

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.

In this talk I will present one specific\r\nsubfield of urban reconstruction: image-based facade modeling and reconstruction. In\r\nparticular I will provide an overview of recent automatic and interactive approaches which aim\r\nat the decomposition of facade imagery in order to generate well defined geometric models.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "image", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 674, "image_height": 505, "name": "musialski_2012_aachen-image.jpg", "type": "image/jpeg", "size": 62023, "path": "Publication:musialski_2012_aachen", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/musialski_2012_aachen-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/musialski_2012_aachen-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 844 ], "date_from": "2012-08-22", "date_to": "2012-08-22", "event": "Invited talk at RWTH Aachen University, Computer Graphics Group", "location": "RWTH Aachen, Germany", "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "", "filetitle": "image", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 674, "image_height": 505, "name": "musialski_2012_aachen-image.jpg", "type": "image/jpeg", "size": 62023, "path": "Publication:musialski_2012_aachen", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/musialski_2012_aachen-image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/musialski_2012_aachen-image:thumb{{size}}.png" }, { "description": "slides of the talk", "filetitle": "slides", "main_file": true, "use_in_gallery": false, "access": "public", "name": "musialski_2012_aachen-slides.pdf", "type": "application/pdf", "size": 3872096, "path": "Publication:musialski_2012_aachen", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/musialski_2012_aachen-slides.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/musialski_2012_aachen-slides:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_aachen/", "__class": "Publication" } ]
