bool do_extra_bright

Brighten rendered textures in an extra pass. This slows down rendering (we should use multi-texturing) but is simulates 2*SRC*DST on cards that only support SRC*DST. At least it seems to do this on a RIVA 128.

For debugging: the maximum number of polygons to draw in a frame.

long dbg_current_polygon

For debugging: the current polygon number.

int DrawMode

DrawFlags on last BeginDraw ()

void CacheInitTexture(IPolygonTexture* texture)

Give a texture to csGraphics3DOpenGL to initialize the cache for it. This is used together with the sub-texture optimization and is meant to allocate the space in the cache but not do any actual calculations yet.

void CacheRectTexture(IPolygonTexture* texture, int minu, int minv, int maxu, int maxv)

void CacheLightedTexture(IPolygonTexture *texture)

Set a renderstate boolean.

STDMETHODIMP SetFogMode(G3D_FOGMETHOD fogm)

Get the fog mode.

STDMETHODIMP OpenFogObject(CS_ID id, csFog* fog)

Initiate a volumetric fog object. This function will be called before front-facing and back-facing fog polygons are added to the object. The fog object will be convex but not necesarily closed. The given CS_ID can be used to identify multiple fog objects when multiple objects are started.

STDMETHODIMP AddFogPolygon(CS_ID id, G3DPolygonAFP& poly, int fogtype)

Add a front or back-facing fog polygon in the current fog object. Note that it is guaranteed that all back-facing fog polygons will have been added before the first front-facing polygon. fogtype can be:

• CS_FOG_FRONT: a front-facing polygon
• CS_FOG_BACK: a back-facing polygon
• CS_FOG_VIEW: the view-plane

STDMETHODIMP CloseFogObject(CS_ID id)
