| 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. */ |
