A sequential version of a well-known isosurfacing algorithm is algorithmically enhanced for a particular type of SIMD architecture. The SIMD implementation takes full advantage of the data parallel nature of the algorithm, and experiments have proven the implementation to be highly scalable. A parallel tool, which can generate 170 K polygons/s, gives scientists the means to explore large 3D scalar or vector fields interactively.<<ETX>>","PeriodicalId":164549,"journal":{"name":"Proceedings Visualization '92","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122307030","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}

By explicitly designing for ease of programming, it was possible to produce a visualization system which is powerful, easy to use, and rapidly improving.

The techniques interpret program behavior in light of user-defined abstractions and generate animations based on a logical, rather than a physical, view of time. If this interpretation succeeds, the resulting animation is easily understood. If it fails, the programmer can be assured that the failure was not an artifact of the visualization. It is shown that these techniques can be generally applied to enhance visualizations of a variety of types of data as they are produced by parallel, MIMD (multiple instruction stream, multiple data stream) computations.<<ETX>>","PeriodicalId":164549,"journal":{"name":"Proceedings Visualization '92","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129316952","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 approach was applied to sea-surface temperature data and was found to be effective in showing fuzzy details embedded in the data, and in drawing the viewer's attention. This approach and these methods could play a significant role in the display of browse products for massive data and information systems.<<ETX>>","PeriodicalId":164549,"journal":{"name":"Proceedings Visualization '92","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123508644","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}
