Contains both high-level and low-level routines for handling 3d graphics primitives. To allow for rendering with either DirectX or OpenGL, the graphics engine uses a structure (gr_screen) with function pointers to all the standard 3d operations (such as initializing the screen, page flipping, displaying primitives etc.). There are basically two sets of source files: grd3d* (DirectX) and gropengl* (OpenGL).
Major Classes/Functions/Structs
| Class/Group/Struct | Method/Function/Element | Notes |
|---|---|---|
| gr_screen/screen global struct | res, mode, aspect etc. | Contains all info about screen setup (bits, resolution, etc) |
| gf_* functions | Wraps standard 3d functions such as page flip, render buffer etc. allowing the engine to abstract DirectX and OpenGL functions. | |
| gf_render_buffer() | Main rendering call for models (ships etc.). Wraps buffer rendering modes in DirectX/OpenGL. | |
| gr_* functions | gr_init() | Initialises graphics engine (either DirectX or OpenGL) |
