帧缓冲区对象错误？

Question

我想在程序中实现一个Framebuffer对象。我已经包括了

#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

我创建Framebuffer对象的代码如下：

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

当我运行以下代码来创建顶点缓冲区对象时，项目编译：

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

Answer 1

Framebuffer被认为是一个单词，因此请使用downcase buffers并从常量中删除下划线：

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