// height field test file                           5/16/95  4:31 am

// You can use this file as a starting point to test new POV landscapes 
// generated by the "gforge" program (or anything else).

// Output from "gforge" generator module used for height field:
// "gforge -mesh 512 -pow 1.3 -dim 2.15" will generate an output.tga
// similar to that used to generate the sample landscap.jpg image.

// Have fun...!                John Beale <beale@jump.stanford.edu>
