Using Framebuffer Objects

We describe how to use framebuffer objects to render to an off-screen
buffer (i.e., renderbuffer) or to render to a texture. Before we can use a
framebuffer object and specify its attachments, we need to make it the
current framebuffer object. The glBindFramebuffer command is used to
set the current framebuffer object.

void glBindFramebuffer (GLenum target , GLuint framebuffer )

target must be set to GL_READ_FRAMEBUFFER ,

GL_DRAW_FRAMEBUFFER , or GL_FRAMEBUFFER

framebuffer framebuffer object name

Note that glGenFramebuffers is not required to assign a framebuffer
object name before it is bound using glBindFramebuffer . An application
can specify an unused framebuffer object name to glBindFramebuffer .
However, we do recommend that OpenGL ES applications call
glGenFramebuffers and use framebuffer object names returned by
glGenFramebuffers instead of specifying their own buffer object names.
