quake3 bsp face types

cody · 2002-06-28T15:26:32

i have written a small q3 map renderer and it works quite well with most geometry. but there are face types in the bsp file where i dont know how to render them. normal geometry is rendered as a tringle fan, ok thats good. but there are objects called meshes an when i render them as a tringle fan it doesnt look right. also as tringle strip or tringle list. i have looked at some tutorials and they dont even try to render meshes. and in a description of the bsp file format there was written: "render it as a tringle list"... well that just doesnt work... any suggestions or links to a good explanation appreciated!

s:
struct MapSurface
{
int shaderNum;
int lightmapNum;

int firstVert;////indices for vertex list
int numVerts;

int type;

int firstIndex;//for mesh index list
int numIndexes;
};

i2numIndexes should be i2 "smaller than" s.numIndexes
(forum stripped away the html stuff)

vertices is my vertex list.
meshverts is the mesh index list.

I think I see the problem now. Meshverts are offset from the first vertex of the face.

Try

v=&vertices[s->firstVert + meshverts[i3]];
