It is important to understand how the SLIDE renderer is using OpenGL, so that you can design a scene which will render quickly.
| SLIDE | OpenGL | Software |
|---|---|---|
| Architecture | State Machine | Recursive Graph Traversal |
| Matrix Transformations | Hardware Matrix Stack Push and Pop |
Stored on C Call Stack |
| Surface Attributes Texture Maps |
Attribute Stack Push and Pop |
