Abstract��A feature of OpenGL is operating system and window system independent. The approach of OpenGL implementations based on PC, including the software implementation, Hardware-accelerated implementation, and the implementation across different platform was analyzed. Furthermore, the performance of OpenGL implementations was measured based on Windows operation systems and Linux distributions with SPECViewperf 9.0 benchmark. The results indicate that Hardware-accelerated OpenGL implementation can attain optimized performance. And for PC platform, the performance of OpenGL implementations is affected by operating system and window system. Benchmarking and Performance Evaluation helps us to select a platform for optimized performance of OpenGL.
