Abstract:
A 3D videographics system including:a memory storing polygon vertex data, and a 3D graphics engine including a graphics pipeline having at least a transform unit, a rasterizer, a texture unit and a pixel engine, said 3D graphics engine generating and displaying images at least in part in response to said polygon vertex data, said 3D graphics engine comprising a vertex cache arrangement operatively coupled to said memory, said vertex cache arrangement caching said polygon vertex data from said memory prior to use by said 3D graphics engine transform unit, wherein said polygon vertex data includes an indexed polygon vertex data structure and said vertex cache arrangement operates in accordance with said indexed polygon vertex data structure representation to cache vertex attribute data and make it available for efficient access by the 3D graphics engine transform unit without requiring explicit resorting of said polygon vertex data for image display.
