说明：  在三维绘图蓬勃发展的过程中，计算机公司推出了大量的三维绘图软件包。其中SGI公司推出的OpenGL，作为一个性能优越的图形应用程序设计界面（API）异军突起，取得了很大的成就。它以高性能的交互式三维图形建模能力和易于编程开发，得到了Microsoft、IBM、DEC、Sun、HP等大公司的认同。因此，OpenGL已经成为一种三维图形开发标准，是从事三维图形开发工作的必要工具。
(Three-dimensional graphics in the growth and development, the computer company to launch a large number of three-dimensional graphics package. SGI Introduces One of the OpenGL, superior performance as a graphics application programming interface (API) emergence, has made great achievements. It is high-performance interactive three-dimensional graphics modeling capabilities and ease of programming development, have been Microsoft, IBM, DEC, Sun, HP and other large companies recognized. Therefore, OpenGL has become a three-dimensional graphics development standards, is to engage in three-dimensional graphics development work necessary tools.)
