【摘要】 针对OpenGL独立于操作系统和窗口系统的特性,分析了OpenGL基于PC的工作原理,包括泛型实现、硬件实现和OpenGL跨平台实现。使用OpenGL性能特征小组的SPECViewperf9.0对OpenGL在Windows和Linux操作平台上的实现性能进行了测评和对比,并给出相关数据和图表。结果显示,OpenGL运行在硬件模式时会获得更好的性能。在PC平台上,OpenGL的实现性能受操作系统和窗口系统影响。测评方法和结果对选择OpenGL操作平台具有一定参考价值。更多还原

【Abstract】 OpenGL is operation 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 platforms was analyzed.Furthermore,the performance of OpenGL implementations based on Windows operation systems and Linux distributions was measured with OpenGL Performance Characterization group’s SPECviewperf 9.0 benchmark and some performance figures were given.The results indicate that Hardware-accelerated OpenGL implementation can attain optimized performance.And for PC platform,the performance of OpenGL implementations was affected by operation system and window system.Benchmarking and Performance Evaluation help us to select a platform for optimized performance of OpenGL.更多还原
