They have become popular in graphics, vision, and HCI communities as they enable numerous applications such as 3D capture, gesture recognition, virtual fitting, etc. Nowadays, common sensors can deliver a stream of color images and depth maps in VGA resolution at 30 fps. While the color image is usually of sufficient quality for visualization, depth information (represented as a point cloud) is usually too sparse and noisy for readable rendering.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121125591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the popularity of multi-touch tablets and styluses, sketching has become a more popular means of human-computer interaction. However, accurately recognizing sketches is rather challenging, especially when they are drawn by non-professionals. Therefore, automatic sketch understanding has attracted much research attention. To tackle the problem, we propose to segment sketch drawings before analyzing the semantic meanings of sketches for the purpose of developing a sketch-based 3D model retrieval system.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116542473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most previous works rely on reusing motion capture data. They also need an offline preprocessing step to either build motion graphs or perform motion analysis. On the other hand, an online motion synthesis algorithm [Hämäläinen et al. 2014] can produce physically plausible motions including balance recovery and dodge projectiles without prior data. They use a kd-tree sequential Monte Carlo sampler to optimize the joint angle trajectories. We extend their approach and propose a new objective function to create two-character animations in a close-range combat. The principles of attack and defense are designed according to fundamental theory of Chinese martial arts. Instead of following a series of fixed Kung Fu forms, our method gives 3D avatars the freedom to explore diverse movements and through pruning can finally evolve an optimal way for fighting.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129486623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Reducing geometry-processing overhead for novel viewpoint creation","authors":"Francisco Inácio, J. P. Springer","doi":"10.1145/2787626.2792599","DOIUrl":"https://doi.org/10.1145/2787626.2792599","url":null,"abstract":"Maintaining a high steady frame rate is an important aspect in interactive real-time graphics. It is mainly influenced by the number of objects and the number of lights to be processed for a 3d scene. The upper-bound effort for rendering a scene is then defined by the number of objects times the number of lights, i. e. O(NO · NL). Deferred shading reduces this upper bound to the number of objects plus the number of lights, i. e. O(NO + NL), by separating the rendering process into two phases: geometry processing and lighting evaluation. The geometry processing rasterizes all objects but only retains visible fragments in a G-Buffer for the current viewpoint. The lighting evaluation then only needs to process those surviving fragments to compute the final image (for the current viewpoint). Unfortunately, this approach not only trades computational effort for memory but also requires the re-creation of the G-Buffer every time the viewpoint changes. Additionally, transparent objects cannot be encoded into a G-Buffer and must be separately processed. Post-rendering 3d warping [Mark et al. 1997] is one particular technique that allows to create images from G-Buffer information for new viewpoints. However, this only works with sufficient fragment information. Objects not encoded in the G-Buffer, because they were not visible from the original viewpoint, will create visual artifacts at discontinuities between objects. We propose fragment-history volumes (FHV) to create novel viewpoints from a discrete representation of the entire scene using current graphics hardware and present an initial performance comparison.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133117488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
