OpenGL 4.3配置教程

下载开发包

需要下载的开发包主要包含如下几个组件：freeglut+glew+ OpenGL.Development.Cookbook+源码+GLM+SOIL.

Opengl SDK并不存在，寻找真正的OpenGL开发工具

1、下载

这些软件需要FQ才能下载，所以提供了完整压缩包：

freeglut (latest version available from: ​​http://freeglut.sourceforge.net​​)

GLEW (latest version available from: http://glew.sourceforge.net)

GLM (latest version available from: ​​http://glm.g-truc.net​​)

SOIL (latest version available from: http://www.lonesock.net/soil.html)

OpenGL.Development.Cookbook 所需的库

2、解压

 OpenGL 4.3配置教程_.net_02

3、运行glew测试工具

4、查看信息

 说明：这些函数都封装在glew中，我们完成一半了

编译
