Abstract: A method of combined exchange of image data and further data being related to the image data, the image data being represented by a first two-dimensional matrix of image data elements and the further data being represented by a second two-dimensional matrix of further data elements is disclosed. The method comprises combining the first two-dimensional matrix and the second two-dimensional matrix into a combined two-dimensional matrix of data elements.

Abstract: A computer graphics system renders an image using forward texture mapping. Image pixels form a pixel grid in a screen space. Objects of the image are modeled by primitives. A texture memory (134) stores a texture map with texels forming a texel grid in a texture space. A rasterizer (120) determines for each primitive in the texture space associated texels that at least partly fall within the primitive and assigns texel attributes to those texels. A texel shader (130) transforms texel attributes to color attributes. A contribution filter (810) filters a continuous signal describing the primitive, yielding, when sampled for a given texel position, a respective contribution factor providing a measure of overlap of the corresponding texel with the primitive in texture space. A screen space resampler (140) resamples color attributes of the texels according to the pixel grid forming display pixel data using the contribution factor as a weight.
