帧缓冲区对象错误？

Question

我想在我的程序中实现一个Framebuffer对象。我已经包括

#include <GL/glew.h> 
#include <GL/glut.h> 

我收到以下错误：

error: ‘glGenFrameBuffers’ was not declared in this scope 

error: ‘GL_FRAME_BUFFER’ was not declared in this scope 

error: ‘glBindFrameBuffer’ was not declared in this scope 

我的代码来创建帧缓冲区对象如下：

GLuint fbo; 
glGenFrameBuffers(1 , &fbo); 
glBindFrameBuffer(GL_FRAME_BUFFER, fbo); 

当我运行下面的代码来创建项目编译的顶点缓冲区对象：

GLuint vbod; 
glGenBuffers(1 , &vbod); 
glBindBuffer(GL_ARRAY_BUFFER, vbod); 

Answer 1

帧缓冲区被认为是一个字，所以使用downcase buffers，并从不断删除下划线：

GLuint fbo; 
glGenFramebuffers(1 , &fbo); 
glBindFramebuffer(GL_FRAMEBUFFER, fbo);
