/**
|
|
* \mainpage The VBO builder module
|
|
*
|
|
* This module hooks into the GL dispatch table and catches all vertex
|
|
* building and drawing commands, such as glVertex3f, glBegin and
|
|
* glDrawArrays. The module stores all incoming vertex data as arrays
|
|
* in GL vertex buffer objects (VBOs), and translates all drawing
|
|
* commands into calls to a driver supplied DrawPrimitives() callback.
|
|
*
|
|
* The module captures both immediate mode and display list drawing,
|
|
* and manages the allocation, reference counting and deallocation of
|
|
* vertex buffer objects itself.
|
|
*
|
|
* The DrawPrimitives() callback can be either implemented by the
|
|
* driver itself or hooked to the tnl module's _tnl_draw_primitives()
|
|
* function for hardware without tnl capablilties or during fallbacks.
