Much effort has been devoted to visual displays that are lightweight and have high resolution. Such efforts are warranted since visual displays are still the dominant output devices used by most computing systems. Auditory displays are now becoming the norm of multimedia systems in addition to visual displays. Whereas vision is best suited for perceiving text and graphics, and audition for speech and music, the sense of touch is intimately involved in nonverbal communication. Whether it is a tap on the shoulder to get someone's attention or a firm handshake to convey trust, touch enables us to exchange information directly with people and the environment through physical contact. The skin is the largest organ of our body, yet only a small portion of it (i.e., the hands) is engaged in most human-computer interactions.","PeriodicalId":192758,"journal":{"name":"ACM SIGGRAPH 2005 Courses","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114729732","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}

However, no comparable abstraction properly expresses the equally important task of data storage and access. This paper presents programmable address translation as a powerful abstraction for defining complex, point-indexable GPU data structures. This abstraction enables GPU programmers to separate algorithm and data structure definitions, greatly simplifying algorithmic development and enabling reusable and interchangeable data structures. We characterize a large body of previously published GPU data structures in terms of our abstraction and define the basic operations that these high-performance structures must support. We also present Glift, a generic template library implementation of the abstraction. We demonstrate the use of Glift in simple examples, and describe two applications not previously possible on GPUs due to the complexity of the required data structures: adaptive shadow maps and octree 3D textures. Lastly, we show that our example Glift data structures perform comparably to or better than handwritten implementations while requiring only a fraction of the programming effort.
