| Abstract: | With the efficient use of computation capacity and programmability provided by graphics processing unit(GPU)of underlying graphics hardware, most of computation from CPU are isolated. Vertex program and fragment program are used for shadow computation, and then the paper accelerates shadow rendering on complex geometry scene. It chooses an image-space shadow algorithm, shadow mapping, for GPU accelerated rendering. The algorithm in Cg shading language and OpenGL is implemented, it can satisfy the requirement of complex 3D application, and gives convincible real-time rendering results. |
