Hi everyone,

We talked about Wei's new paper on texture mapping last week.
Bellow is the abstract of that paper and I'll be talking about
it tomorrow.

Tile-Based Texture Mapping on Graphics Hardware
Li-Yi Wei

Abstract:
Texture mapping has been a fundamental feature for commodity
graphics hardware. However, a key challenge for texture
mapping is how to store and manage large textures on graphics
processors. In this paper, we present a tile-based texture
mapping algorithm by which we only have to physically store a
small set of texture tiles instead of a large texture. Our
algorithm generates an arbitrarily large and non-periodic
virtual texture map from the small set of stored texture
tiles. Because we only have to store a small set of tiles, it
minimizes the storage requirement to a small constant,
regardless of the size of the virtual texture. In addition,
the tiles are generated and packed into a single texture map,
so that the hardware filtering of this packed texture map
corresponds directly to the filtering of the virtual texture.
We implement our algorithm as a fragment program, and
demonstrate performance on latest graphics processors.
