Transform Feedback Buffers

Transform feedback objects are primarily responsible for managing the state representing capture of vertices into buffer objects. This state includes which buffers are bound to the transform feedback buffer binding points. Multiple buffers can be bound simultaneously for transform feedback and subsections of buffer objects can also be bound. It is even possible to bind different subsections of the same buffer object to different transform feedback buffer binding points simultaneously. To bind an entire buffer object to one of the transform feedback buffer binding points, call:

void glBindBufferBase(GLenum target, GLuint index,                         GLuint buffer);

Binds the buffer object with name buffer to the ...
