OpenGL includes the following error codes. Error codeDescription GL_INVALID_ENUMGLenumargument out of range. GL_INVALID_VALUENumeric argument out of range. GL_INVALID_OPERATIONOperation illegal in current state. GL_STACK_OVERFLOWFunction would cause a stack overflow. ...
GLenum err; while((err = glGetError()) != GL_NO_ERROR) { // Process/log the error. } Meaning of errors TheglGetErrorfunction returns one of the following error codes, or GL_NO_ERROR if no (more) errors are available. Each error code represents a category of user error. GL_INVALI...

(详情参见GL Error Codes) OpenGL保存最近一次的各种类型的错误,每调用一次glGetError()就返回一个类型的错误代码并清除其记录。如果一个错误记录都没有,就返回GL_NO_ERROR。 这个辅助函数可用于查询最近所有命中的错误: 1intCheckGLErrors()2{3interrCount =0;4for(GLenum currError = glGetError(); currError...
The return value for gluErrorString is a pointer to a descriptive string that corresponds to the OpenGL, GLU, or GLX error number passed in the errorCode parameter. The defined error codes are described in the OpenGL Reference Manual along with the function or function that can generate them....

The following codes is to setup a FBO and framebuffer-attachable images before the rendering loop is started. Note that not only a texture image is attached to the FBO, but also, a renderbuffer image is attached to the depth attachment point of the FBO. We do not actually use this depth...
