RAYMOVI.PRG

   RAYMOVI.PRG renders 3-dimensional scenes in a world of reflective and 
refractive spheres, using ray tracing techniques. Animated sequences of 
frames can be generated, showing reflective balls linked and bouncing in 
a gravitational field. They resemble a string of bouncing pearls.

   RAYMOVI.PRG runs only on a color ST in low resolution. 1 Meg is required 
to generate images with resolutions greater than one ray per pixel or for 
replay of movies from RAM. Operation with only 512K is possible, but will 
produce slightly aliased pictures (one ray per pixel) which can only be 
displayed statically, slowly from floppy, or from hard disk (if you have 
a disk blaster program).

   The files in RAYMOV2S.ARC, the source arc, are:

C Sources:  	BLASTRAM.C, MAIN.C, WNDOWS.C, FILE.C, MOVIE.C, SHADE.C, 
		FIND.C, SUPPORT.C
Include files:	RTD.H, STYLE.H, COLORS.H, EXTERN.H
Pgm Generation: MAKEFILE, BLASTRAM.LNK, RAYMOVI.LNK
RAYMOVI.DOK	documentation
PEARLS		the numeric description of an interesting scene

   RAYMOVI was last compiled with ALCYON. The MAKEFILE and *.LNK are 
(therefore) pretty crufty. Use them accordingly.

   RAYMOVI requires an 8K stack. Modify your copy of gemstart.s (or
whatever defines your stack size) appropriately.
