A Medium Pipelined Triangle Setup Structure For 3d Graphics Engine

This paper proposed a medium scale pipelined triangle setup structure for designing a cost effective and high performance 3D graphics rendering system. Triangle setup stage handles the initialization of all the necessary, parameters for the rasterization step, and plays a role of balancing the work between the geometry and the rasterization steps. Thus it may cause a significant influence to the overall performance. In this work, a hardware controlled setup stage is designed for high performance. And the triangle strip is used as a basic input format to process and the rasterization stage is designed with a special buffer to process the triangle strips effectively. Performance results chow that the proposed structure call reduce hardware cost by about 48% with a reasonably balanced performance. Therefore it is suitable for practical graphics system designs.
