Procedural Texture Mapping on FPGAs

Procedural textures can be effectively used to enhance the visual realism of computer rendered images. Procedural textures can provide higher realism for 3-D objects than traditional hardware texture mapping methods which use memory to store 2-D texture images. This paper proposes a new method of hardware texture mapping in which texture images are synthesized using FPGAs. This method is very efficient for texture mapping procedural textures of more than two input variables. By synthesizing these textures on the fly, the large amount of memory required to store their multidimensional texture images is eliminated, making texture mapping of 3-D textures and parameterized textures feasible in hardware. This paper shows that using FPGAs, procedural textures can be synthesized at high speed, with a small hardware cost. Data on the performance and the hardware cost of synthesizing procedural textures in FPGAS are presented. This paper also presents, the FPGA implementations of two Perlin no...
