Abstract
A method, system, and computer program product for filtering textures applied to a surface of a computer generated object permits an application program running on a computer system to significantly increase the graphics capabilities and performance of the computer. Rendering data for a pixel of the object is received from the application program, and a first and second set of texture coordinates is generated. Next, the first and second sets of texture coordinates are used to obtain a first and second texture sample from a texture image. The first and second texture samples are then blended together to produce a texture sample having a greater degree of filtering. This produced texture sample having a higher degree of filtering is stored in a frame buffer for subsequent display. The filtering process of the present invention can be performed either by conducting multiple passes through a graphics pipeline having a single texture unit or by conducting one pass through a graphics pipeline having multiple texture units. The filtering process of the present invention can also be performed by conducting multiple passes through a graphics pipeline having multiple texture units.
