摘　　要：针对目前一些Web 3D应用系统实时渲染引擎在材质真实感表现方面的不足,阐述了利用图形处理器的可编程特性提升实时渲染引擎质感表现的思路,引入Cg高级着色语言,探讨了Cg shader在Web 3D虚拟展示中的应用。最后,以油漆材质表现的应用实例验证了方法及技术的可行性,取得初步的研究成果。To the deficiency of real-time rendering engine in material realization, the idea is expounded of using to the of programmable characteristic of Graphic Processing Umt advancing material realization of real-time rendering engine in some web 3D system , introduced high level shading language--Cg language, discussed how to apply Cg shader to deskto Pvirtual reality system on internet. Finally, feasibility has be verified of the method and technology with the application example of oil paint material realization, and some preliminary results have been acquired.
