Chapter 1 Octree Textures on the GPU
Sylvain Lefèbvre, Samuel Hornus, Fabrice Neyret · 2002
Texture mapping is a very efficient technique to enrich the appearance of polygonal models with details. Textures do not only store color information, but also normals for bump mapping and various shading attributes to create appealing surface effects. However, texture mapping requires parameterizing a mesh, by associating a 2D texture coordinate with every mesh vertex. Distortions and seams are often introduced by this difficult process, especially on complex meshes.
