Abstract

Computer graphics processing operations are executed on information relating to a model of one or more three-dimensional objects which includes texture information. The method includes a rendering step that comprises a transformation step allowing for both affine and non-affine two-dimensional image transformations, and comprises transforming the texture information. This uses a filtering step to suppress aliasing artifacts of interior parts of one or more textured primitives in the rendered image. In particular, the method uses the filtering to deliver partial colors at both sides of the edges of such primitive. Eventually, aggregation of the partial colors suppresses artifacts from edge aliasing of the primitive in question.
