I read the virtcliptex.c in the /usr/share/Performer/src/pguide/libpf/C
directory. I just cannot understand why should the program change minLod , maxLod and numOfEffectiveLevel every frame. After all what on earth is virtual
clipmap? How does it overcome the limitation of the hardware for addresing?
