ABSTRACT:
Computer-implemented methods of pre-filtering texture data and methods of generating a filter control for pre-filtering texture data for generating a graphics image are disclosed. The disclosed methods include determining encoded pre-filter characteristics representing a measure of the maximum change in a texture due to moving a least one pixel any direction in a graphics image. The encoded pre-filter characteristics can be used to control filtering of texture data for texture mapping a graphics image.
