I am writing a game and didn''t always worry about the gluPerspective function, but now it became more and more interesting for me as I noticed that my player can''t look very far, which looks really crappy. I increased the far value and my FPS dropped tremendously (from 55.0 to 155.0) But you can look further. Is there any way to increase the drawing speed for complex models? ( I hope that''s the right term for "non-heightmaps" ) I was thinking about a kind of LOD but I couldn''t figure out how to apply it to a model. Maybe some spline thingie with the vertex normals controlling the control points, but that''s also hard for me. Is there any way to do this? A sample implementation would be great. Gahre

Im not quite sure whether you mean if you can draw the world faster or not, but If thats what you want, look into BSP trees. They''re what make Quake 3 so fast.

Hope that helps.

Isn''t 155 a better frame rate than 55 frames per second?
