I’m trying to convert a point’s(actually all the vertices of a terrain mesh) world coordinates to screen coordinates using gluProject().Shouldn’t the coordinates I obtain from gluProject() always be between 0 and 640 for x and 0 and 480 for y(assuming of course 640x480 res)?I’m getting negative values for points that get clipped out(I suppose that’s normal) but when I get close to the terrain I get some big values,like >100000 and I don’t think thats normal,is it? could it be cause these points I get large valiues for are clipped by the near clipping plane?Anybody else has another idea?
