Because of the scale and the growth rate beyond any existing social systems, cyberbusiness imposes challenging requirements for modeling, design, development and operation. Homotopy modeling is based on novel space-time modeling with cellular spatial structures. The paper discusses homotopy modelling as the architectural foundation of cyberworlds.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128792152","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}

This paper outlines the impact of advances in homotopy research and technology and also the impact of the new style of business that is driving it forward. The homotopy technology includes breakthroughs that provide: a unified data architecture, advanced neural net hardware, and advanced asynchronous hardware technology. The impact of these three elements will pave the way into the next generation of information technology.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134048156","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}

While previous work has focused on these higher-level systems, we focus on the infrastructure provided by the graphics system. We describe how a graphics system designed with synthetic characters in mind can be behavior friendly, simplifying motor and behavior system construction and making new characters easier to create. The system described in this paper was the underlying support for \"Swamped!\", an interactive 3D cartoon demonstrated in the Enhanced Realities section of SIGGRAPH 98. We describe how our design and implementation allowed us to achieve real-time performance in this Java application.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131404194","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}

The points of the triangle, when lifted to the surface, form a linear spline approximation to the surface. We are interested in the error between the surface and the linear approximant. In fact, we are interested in building triangulations in the plane such that the induced linear approximant is near-optimal with respect to a given error. We describe a new method, which iteratively adds points to a \"Delaunay-like\" triangulation of the plane. We locally approximate f by a quadratic surface and utilize this surface to establish an edge-flipping criterion for a convex quadrilateral that enables us to minimize the error between the surface and the triangulation.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129273870","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}

Monolith has taken on the role of promoting this new technology from the level of theory to a level from which practical applications can be developed. In order to maintain contact with both researchers and business, Monolith has developed a business model in which Monolith will not market commercial products itself but will obtain funding largely through the licensing of intellectual property. Monolith's IP strategy focuses on obtaining broad fundamental IP rights and then broadly licensing those rights on reasonable terms to create standards. In this way, the licensing revenue will provide on-going funding for research and researchers can focus on their research rather than on the business of getting funding.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115201583","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}

We present the algorithm, and demonstrate its working in a real-time model of walking cartoon legs.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124144999","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}

In areas of a surface defined by the combination of multiple skeletal primitives, we compute a mapping through relations found with the zero-level surface of a primitive by using the gradient field.","PeriodicalId":165593,"journal":{"name":"1999 Proceedings Computer Graphics International","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125574905","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}
