R_InitOpenGL
|

|
This function is responsible for initializing a valid OpenGL subsystem

for rendering. This is done by calling the system specific GLimp_Init,
|
||||||
|
which gives us a working OGL subsystem, then setting all necessary openGL
|
||||||
|
state, including images, vertex programs, and display lists.
|
||||||
|
|
||||||
|
Changes to the vertex cache size or smp state require a vid_restart.
|
||||||
|
|
||||||
|
If R_IsInitialized() is false, no rendering can take place, but
|
||||||
|
all renderSystem functions will still operate properly, notably the material
|
||||||
|
and model information functions.

This function is responsible for initializing a valid OpenGL subsystem

which gives us a working OGL subsystem, then setting all necessary openGL

state, including images, vertex programs, and display lists.

Changes to the vertex cache size or smp state require a vid_restart.

If R_IsInitialized() is false, no rendering can take place, but

all renderSystem functions will still operate properly, notably the material

and model information functions.
