OpenGL 4.3配置教程

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*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
