/* This is where doing Direct3D on top on OpenGL is quite difficult.
|
|
This method transforms a set of vertices using the CURRENT state
|
|
(lighting, projection, ...) but does not rasterize them.
|
|
They will only be put on screen later (with the POINT / LINE and
|
|
TRIANGLE op-codes). The problem is that you can have a triangle
|
|
with each point having been transformed using another state...
|
|
|
|
In this implementation, I will emulate only ONE thing : each
|
|
vertex can have its own "WORLD" transformation (this is used in the
|
|
TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
|
|
execute buffer use the same state.
|
|
|
|
If I find applications that change other states, I will try to do a
|
|
more 'fine-tuned' state emulation (but I may become quite tricky if
|
|
it changes a light position in the middle of a triangle).
|
|
|
|
In this case, a 'direct' approach (i.e. without using OpenGL, but
|
|
writing our own 3D rasterizer) would be easier. */

- during the rasterization phase, the WORLD matrix will be set to

the Identity matrix */
