SYSTEM FOR ADAPTIVE RESAMPLING IN TEXTURE MAPPING

摘要

An apparatus for mapping primitives of a 3D graphics model from a texture space to a screen space. The apparatus includes a texture memory 134 for storing texture maps. A resampler 132, 140 resamples, for each primitive, data from a texture map that corresponds to the primitive to corresponding pixel data defining a portion of a display image that corresponds to the primitive. The texture space resampler 132 and/or the screen space resampler 140 is operative to select a resampling algorithm for performing the resampling from a respective set of at least two distinct resampling algorithms. The selection is done in dependence on a size of the primitive.
