中文称三维图形标准，是由AT＆T公司UNIX软件实验室、IBM、DEC、SUN、HP、Microsoft和SGI等多家公司在GL图形库标准的基础上联合推出的开放式图形库，它使在微机上实现三维真实感图形的生成与显示成为可能。由于OpenGL是开放的图形标准，用户原先在UNIX下开发的OpenGL图形软件很容易移植到微机上的WindowsNT／95上。-Chinese called 3D graphics standard, is AT &　T' s UNIX Software Lab, IBM, DEC, SUN, HP, Microsoft and other companies in the SGI GL graphics library based on criteria jointly launched the Open Graphics Library, which allows the computer the realization of three-dimensional photorealistic graphics generation and display possible.
