I am planning to add solid texture mapping to a rendering system that I am in the process of writing. The first texture that I plan to map is marble. I have done some reading on this subject and found that Ken Perlin in SIGRAPH 85 Vol 19, Number 3 presents a technique for simulating marble. Unfortunately (after many readings) I do not understand his discussion of the Noise() function. I would appreciate any pointers that could be given on this subject. I particular I would like either code fragments that implement Noise() or suggestions for further reading on the subject. Thanks Paul Wasserman ihnp4!mtunk!paul 201-957-2582 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

If you can't get it any other way then here is a rather strange way that you can get copies of the noise, turbulence, etc. functions mentioned in C. I've been distributing DBW Render source to anyone who sent me either a 400K formatted Mac diskette or a formatted MSDos disk with a SASE to get it back to you. The program's texture functions all appear to be based on that article and there are implementations of both noise and turbulence (with lots of other very instructive code as well).
