A procedural solid texturing system which uses a parameterized function capable of reproducing the most common procedural solid textures, specifically wood, marble, clouds and fire ( ). This model is simple enough to be implemented in hardware, and can be realized in VLSI with as little as 100,000 gates. The invention also includes a method for antialiasing the parameterized procedural textures ( ). The antialiasing includes an expression for the necessary box filter width, a technique for efficiently box filtering the procedural texture by either MIP mapping the color table or using a summed area color table ( ).
