It adapted Daly's visible differences predictor [Daly 1993] and Wilson's transducer function [Wilson 1980; Wilson and Gelb 1984] to measure the response of contrast in human visual system. The transducer function is expressed as:\u0000 where ΦQ(C) represents the response of a contrast stimulus. C is the physical contrast of a stimulus, and S is the sensitivity of this type of contrast stimuli with certain frequency, orientation, background luminance values, etc. Q is a empirical parameter that falls in a wide range of [2.0, 6.0] across different experiments. It suggests the value of Q is adaptive to experimental conditions. A simple adaption of Equ. 1 with fixed Q may bring unexpected errors.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128300626","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 order to speed up the performance of converting citizen behavior into RIB format, the pre-baked RIB method proposed in Tutorial on Procedural Primitives [Hery and Sutton 2001] was applied. By using motion-editing techniques, our crowd characters are able to interact with the environment efficiently. Making use of techniques of Procedural RIB Generation, lighting artists were able to apply secondary masks on crowd characters, and the new motion which is generated on-the-fly during simulation can be rendered efficiently.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131730918","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}

Video material from x/y-stereo displays visualizes the phase changing from two-channel audio signals. The sound source is a special audio composition that can not be realized without direct visualization. It contains full-on, sound-dependent motion dynamics and forms complex \"cathode-ray objects\", which allow direct (not delayed) visual access to the smallest details of the composition. The representation is not limited by the pictures-per-second time frame of television and computer technology. The interconnection of the aural and visual senses arises in an immediate way, and the visualization of sound obtains a new meaning.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"464 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125823670","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}

There are no standard methods for modeling their motions, because their non-linear behavior, which is ruled by the loss of energy, occurs when the discrete particles collide. Therefore, methods for rendering granular materials have not been studied widely. In this paper, we present a new method for rendering photo-realistic granular materials. To model the motion of granular material, we define granular materials as the mass of discrete particles. Then the scattering of light needed for photo-realistic rendering is formulated, and we propose method for efficiently evaluating radiance in granular material based on a radiance caching method.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126984154","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}
