| /** |
| * \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. |
