This talk will present an overview of lapped textures and its subsequent applications in real-time fur rendering and hatching. Lapped textures cover an arbitrary surface by repeatedly instancing a small example texture onto a set of overlapping surface patches. The surface patches define local parametrizations that align to a globally consistent direction field. Because they use a small texture footprint, lapped textures reduce texture memory and bandwidth. This memory savings is particularly important when the texture is volumetric (for fur rendering), or when it is tone-dependent (for hatching).
