Abstract:
A graphic processor having an index processing unit for pre-processing a list of vertices making up a three-dimensional image. The method of pre-processing comprising the following steps. First, decomposing the three-dimensional image into a plurality of primitive elements each defined by a set of vertices, each vertex comprising vertex information stored in a vertex storage area and addressable by a vertex index. Then receiving said vertex indices and creating a set of unique indices identifying a batch of vertices and loading only the vertices corresponding to said unique indices into the vertex storage area. Finally creating transformed primitive elements from transformed vertex information addressed in the vertex storage area using the unique indices.
