OpenGL 3.1将此前引入的OpenGL着色语言“GLSL”从1.30版升级到了1.40版，通过改进程序增强了对最新可编程图形硬件的访问，还有更高效的顶点处理、扩展的纹理功能、更弹性的缓冲管理等等。宽泛地讲，OpenGL 3.1在3.0版的基础上对整个API模型体系进行了简化，可大幅提高软件开发效率。-OpenGL 3.1 will be introduced in the previous OpenGL shading language \"GLSL\" from version 1.30 upgrade to version 1.40, through the improvement program strengthens the latest programmable graphics hardware access, and more efficient vertex processing, expand the texture of the function, more flexible buffer management and so on. Very broadly speaking, OpenGL 3.1 in version 3.0 on the base of the whole API model system is simplified, can greatly improve the efficiency of software development.
