C语言如何用OpenGL
OpenGL就是源译基于C语言的,只需要下载OpenGL的码编SDK库安装即可,在编写源码时:
1、源译橡子星座源码添加头文件glut.h。码编
注意glut.h文件中已经包含gl.h,源译andrroid 系统源码glu.h在实际编译中可以只加入头文件glut.h,很多相关的码编剧情吧 源码例子都是这样的,但是源译在mingwstudio上编译发现,在glut.h前还是码编需要加入glu.h, gl.h.如:
#include <gl/gl.h>
#include <gl/glu.h>
#include <gl/glut.h>
2、在工程中添加OpenGL的源译库,有关命令行加入,码编glu opengl glut库就可以编译了。源译
