Still, their use for high-quality and photorealistic rendering is still in its infancy, in particular for interactive applications. This paper describes a framework for interactively ray tracing point-based models based on a combination of an implicit surface representation, an efficient surface intersection algorithm, and a specially designed acceleration structure. Using this framework allows for interactively ray tracing even highly complex models on a single PC, including global illumination effects and the interactive visualization of a 24-million-point model with ray traced shadows.","PeriodicalId":152934,"journal":{"name":"Proceedings Eurographics/IEEE VGTC Symposium Point-Based Graphics, 2005.","volume":"94 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":"133366039","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}

It uses the common setup of a video projector, a computer-controlled turntable and a single camera. Geometry is acquired using a combination of gray code and phase-shift projections, and it is stored and processed in a point-based representation. We achieve high accuracy by careful calibration of camera, projector, and turntable axis. In addition, we make use of the projector's calibration and extend it to a calibrated light source, allowing for a simple reconstruction of material properties for each surface point. We alternatively use a Lambertian reflectance model, or fit a Phong reflectance model to the samples under different turntable orientations. The acquisition pipeline is entirely point-based, avoiding the need of triangulation during all processing stages.","PeriodicalId":152934,"journal":{"name":"Proceedings Eurographics/IEEE VGTC Symposium Point-Based Graphics, 2005.","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131753230","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 output mesh carries the geometric information present in the input model, while information about color and other surface attributes is separated and stored in textures. The point cloud is triangulated and decimated so it adequately represents the object geometry. Using EWA splatting, we compute textures patches for all triangles in the mesh. In an iterative process, the size of the texture patches is chosen adaptively such that texture information is preserved during the conversion. The texture filtering capabilities of EWA splatting ensure that no texture aliasing occurs. Finally, the texture patches are compiled into a texture atlas. Aside from colors, other surface attributes can be treated similarly. Normal maps can be computed to allow for further simplification of the output mesh while maintaining high visual quality.","PeriodicalId":152934,"journal":{"name":"Proceedings Eurographics/IEEE VGTC Symposium Point-Based Graphics, 2005.","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127905102","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}

A decade ago 3D graphics moved from dedicated and expensive engineering graphics workstations to normal PCs. Sophisticated graphics was now accessible to a much larger audience and developer pool than before. A similar revolution is happening right now as mobile devices such as PDAs and cellular phones have their own standard 3D APIs, high-quality color displays, and even hardware acceleration is starting to become available. This paper covers the graphics capabilities of modern mobile devices, their limitations, and graphics APIs designed for these devices.
