Procedural modeling enables us to quickly generate large city layouts, while manual modeling allows us to hand-craft every aspect of a city. We introduce transformation and merging operators for both topology preserving and topology changing transformations based on graph cuts. In combination with a layering system, this allows intuitive manipulation of urban layouts using operations such as drag and drop, translation, rotation etc. In contrast to previous work, these operations always generate valid, i.e., intersection-free layouts. Furthermore, we introduce anchored assignments to make sure that modifications are persistent even if the whole urban layout is regenerated.\n", "authors_et_al": false, "substitute": null,

"Direct Artist Control for Procedural Content Generation of Urban Environments", "date": "2010-10", "abstract": "Creating 3D digital assets of urban environments is a challenging task, requiring a significant amount of manual labor. 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. Finally, as real-time performance of generation algorithms is paramount if they are to be used in a production setting, we introduce an algorithm able to parallelize the work of L-system generation to thousands of processors.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "", "main_file": false, "use_in_gallery": false, "access": "public", "name": "lipp_markus-2010-DAC-.pdf", "type": "application/pdf", "size": 921518, "path": "Publication:lipp_markus-2010-DAC", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/lipp_markus-2010-DAC-.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/lipp_markus-2010-DAC-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 680 ], "co_supervisor": [ 194 ], "duration": "3 years", "reviewer_1": [ 193 ], "reviewer_2": [ 194 ], "rigorosum": "2010-11-16", "supervisor": [ 193 ], "research_areas": [], "keywords": [ "Procedural Modeling", "Urban Layouts", "Interactive Control" ], "weblinks": [], "files": [ { "description": "", "filetitle": "", "main_file": false, "use_in_gallery": false, "access": "public", "name": "lipp_markus-2010-DAC-.pdf", "type": "application/pdf", "size": 921518, "path": "Publication:lipp_markus-2010-DAC", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/lipp_markus-2010-DAC-.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/lipp_markus-2010-DAC-:thumb{{size}}.png" }, { "description": "Pdf of thesis", "filetitle": "Thesis", "main_file": true, "use_in_gallery": false, "access": "public", "preview_image_width": 1186, "preview_image_height": 1054, "name": "lipp_markus-2010-DAC-Thesis.pdf", "type": "application/pdf", "size": 17993864, "path": "Publication:lipp_markus-2010-DAC", "preview_name": "lipp_markus-2010-DAC-Thesis:preview.png", "preview_type": "image/jpeg", "preview_size": 403894, "url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/lipp_markus-2010-DAC-Thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/lipp_markus-2010-DAC-Thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "GAMEWORLD" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2010/lipp_markus-2010-DAC/", "__class": "Publication" }, { "id": "LIPP-2010-PGMS", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": null, "title": "Parallel Generation of Multiple L-Systems", "date": "2010-10", "abstract": "This paper introduces a solution to compute L-systems on parallel architectures like GPUs and multi-core CPUs.

Procedural modeling techniques strive to reduce the manual work an artist has to perform when modeling architecture. In previous work, those techniques were successfully applied to the creation of architecture. However, previous methods have a limited usability, as they are based on text editing. This makes modeling unintuitive and diminishes the advantages of procedural modeling.\n\nTherefore, methods to interactively create procedural architecture, using a graphical user interface, are explored in this thesis. As interactivity also requires real-time rendering performance, methods to accelerate the generation of architecture are investigated. Further, the thesis provides a detailed report on previous procedural architecture generation techniques.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 576, "image_height": 338, "name": "LIPP-2007-CGA-.jpg", "type": "image/jpeg", "size": 89121, "path": "Publication:LIPP-2007-CGA", "url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/LIPP-2007-CGA-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/LIPP-2007-CGA-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 680 ], "date_end": "2007", "date_start": "2007", "matrikelnr": "0125260", "supervisor": [ 193 ], "research_areas": [ "Modeling" ], "keywords": [ "computer generated architecture", "procedural modeling" ], "weblinks": [], "files": [ { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 576, "image_height": 338, "name": "LIPP-2007-CGA-.jpg", "type": "image/jpeg", "size": 89121, "path": "Publication:LIPP-2007-CGA", "url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/LIPP-2007-CGA-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/LIPP-2007-CGA-:thumb{{size}}.png" }, { "description": null, "filetitle": "Thesis", "main_file": true, "use_in_gallery": false, "access": "public", "name": "LIPP-2007-CGA-Thesis.pdf", "type": "application/pdf", "size": 10045616, "path": "Publication:LIPP-2007-CGA", "url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/LIPP-2007-CGA-Thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/LIPP-2007-CGA-Thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "GAMEWORLD" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2007/LIPP-2007-CGA/", "__class": "Publication" } ]
