플랫폼 기반 3D 그래픽 Geometry Processor 구현

The geometry stage, which perform and lighting operations of vertices, became the critical part in 3D graphics pipeline. In this paper, we have planned and designed the Geometry Processor for the better and more efficient way to process the real-time 3D using the floating point unit. We also designed a verification system for Geometry engine. It is implemented with Xilinx- Virtex4 and ARM based SOC Platform. We did a verification of the processor at 25㎒ using SoC Base 1.0 Platform, and confirmed proper lighting process using three light of Ambient, Specular, Diffuse effect.
