Abstract
We present a technique for efficient management of large textures and its real-time application to geometric models. The
proposed technique is inspired by the clipmap [12] idea, that caches in video memory a subset of the texture mipmap pyramid.
Based on this concept, we define some structures and a different management allowing its implementation on a personal
computer without specific graphics hardware. Finally, we present the results of the application in a terrain visualization system,
using several simultaneous textures with a detail up to 0.25 meters per texel, covering a 60,000 km2 area.
