                           General Release Notes
*=------------------------------------------------------------------------=*


 * This code was written with Dark Basic V1.07

 * This release shows a simple example of a common point rotation method.
   It shows an array of rotated points around a moving camera. 

 * Common point rotation is really simple, and works very well on grids
   or objects that share planes of vertices.  All you do, is pre-mult
   all the unique edge values along X, Y & Z, so then inner loops becomes
   nothing more than a series of add & sub's.  This main routine has only
   1 mult and 2 divides per pixel.   It's more hassle to setup in 3D, but
   the results are certainly worth it.
  
 
 * Your welcome to use this code providing you credit me..
