Bit width necessary for solid texturing hardware

The effects of the texture coordinate precision to the image for procedural texture mapping is presented. In our project, we are trying to implement procedural solid texture mapping by hardware. By reducing the number of parameters for our texture mapping model and precision of texture coordinate, we can implement procedural texture mapping with small number of gates. We checked that how many bits were required to produce the image without degrading original by simulation and confirmed that we could have good textured image even with small number of bit width.
