Because power consumption increases almost linearly with GPU workload, the heavy GPU workload imposed by fixed high resolution can be allowed to be actually computed only when there are human perceptible benefits. Some recent techniques are exploited at runtime to reduce the workload such as skipping frames or lowering resolution during rendering. From those techniques, we still observe noticeable artifacts because they did not carefully investigate whether resulting sequences of frames are perceived as containing artifacts or not. Although one of recent studies relies on a user's view distance [Nixon et al. 2014], it can malfunction depending on environmental and biometric limitation.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"419 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122795926","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 a previous study, we developed an algorithm for utilizing the 3-D architecture of volumetric displays [Nakayama et al. 2013]. The 3-D objects designed by the algorithm can exhibit multiple 2-D images towards different directions simultaneously. Figure 2a shows a prototype of a 3-D crystal which has been designed using the proposed algorithm. As shown in Figure 2b, we can recognize three images when we look at it from the respective directions. In other words, the 3-D crystal is independently providing three images with directivity.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123965816","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}

Multiple render targets (MRTs) are one of the new important features of the OpenGL ES 3.x specification. MRTs facilitate rendering multiple render-target textures (called G-buffer) at once, so this feature enables deferred shading; after various geometry data, such as color, normal, reflection, and refraction, are rendered into the G-buffer in the first pass, we can perform screen-space lighting using the G-buffer data in the second pass. Complex lighting with deferred shading is now very common on desktop and console devices.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133636412","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}
