Abstract
A method, system, and computer program product are provided for texture tiling with adjacent information. Adjacency information is supplied for one or more potential tiling directions. In one example, adjacency information is supplied for eight potential tiling directions radiating in eight different directions relative to an original texture image. In another example, adjacency information is supplied for three potential tiling directions. The present invention provides a solution that allows the specification of a texture image as a border to another for texture tiling purposes. This means that when texture addressing extends beyond the region within a texture map another texture image is addressed. During texture processing, in mapping a graphics primitive to adjacent border textures, two steps are carried out. The first step evaluates texture coordinate values to determine when texture coordinates are outside a range of a base texture image being texture mapped. The second step determines which adjacent border texture corresponds to the texture coordinates evaluated to be outside the base image. This determination is made using adjacency information which identifies the direction of the adjacent border texture relative to the base image.
