Our method uses a new data structure called a parametric motion graph to describe valid ways of generating linear blend transitions between motion clips dynamically generated through parametric synthesis in realtime. Our system specifically uses blending-based parametric synthesis to accurately generate any motion clip from an entire space of motions by blending together examples from that space. The key to our technique is using sampling methods to identify and represent good transitions between these spaces of motion parameterized by a continuously valued parameter. This approach allows parametric motion graphs to be constructed with little user effort. Because parametric motion graphs organize all motions of a particular type, such as reaching to different locations on a shelf, using a single, parameterized graph node, they are highly structured, facilitating fast decision-making for interactive character control. We have successfully created interactive characters that perform sequences of requested actions, such as cartwheeling or punching.","PeriodicalId":140639,"journal":{"name":"Proceedings of the 2007 symposium on Interactive 3D graphics and games","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134190629","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}

For this purpose, numerous methods, such as light fields, stereo reconstruction and visual hulls have been extended to model dynamic objects. These methods use multiple cameras to acquire images simultaneously and use the synchronized samples to reconstruct the model for each time instance. However, a large number of cameras are required to obtain compelling results. We introduce an efficient acquisition and modeling schema for dynamic objects with repetitive motions. Our method requires as few as two cameras. The key idea is that repetitive motions can be described by a finite number of states. Images capturing the same state can be grouped together and fed to the later modeling phase as if they are captured from multiple cameras simultaneously. Our work includes an acquisition system with interactive feedback, a graph traversal algorithm to help obtain a near minimum subset of images to sample the object and its motion, and a space-time image optimization method. We demonstrate this system using several datasets with different complexity of motion, and different number of desired viewpoints.","PeriodicalId":140639,"journal":{"name":"Proceedings of the 2007 symposium on Interactive 3D graphics and games","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114821321","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}

If you are holding a hardcopy, you have all the conference's papers before you. If you are viewing the DVD, you also have access to videos and appendices. The location of this symposium is Seattle, Washington, from April 30 to May 2, 2007. In addition to the presentations of the technical papers from these proceedings, the conference also includes a poster session and doctoral seminars. \u0000 \u0000The purpose of the I3D conference is to bring researchers and practitioners of similar interests together to exchange ideas about interactive graphics and games. One of the distinct joys of conferences of this size is that you can meet just about everyone, and there is ample opportunity to talk between sessions and over meals. This is not always possible at a larger conference. If you are an I3D participant in 2007, we hope that you will return to your fellow researchers and remind them of the pleasures of this conference. \u0000 \u0000These proceedings contain 25 excellent papers that were selected out of 72 submissions to the symposium. For those who like to chart trends, we have provided a history of the paper statistics for I3D in a table below. This year, each paper was given at least three reviews, and the vast majority of the reviews came from the PC members.","PeriodicalId":140639,"journal":{"name":"Proceedings of the 2007 symposium on Interactive 3D graphics and games","volume":"394 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114913786","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}
