Abstract
A three dimensional image is textured for display on a screen by firstly receiving data comprising the location of each elementary area (pixel) of the screen and associated image data for that pixel. Texture image data is retrieved from a memory means in dependence on the image data and an appropriate portion of that texture image data is mapped onto the pixel. The number of pixels which share the same associated image data is determined and an incremental change in the mapping of the texture data onto pixels corresponding to a one pixel increment is also determined. For each pixel sharing the same image data as an adjacent pixel the previously derived texture image data for that adjacent pixel is combined with the incremental change in texture image data to thereby derive texture image data for that pixel.
