To install the MTV raytracer is quite simple:

1.	Edit config.h to indicate whether your computer understands void
	or not.  You might also have to define SYSV if you are running on 
	a SYSV system.

2.	Check the Makefile.  The way it is currently distributed it is
	set up to run on suns with the 68881 processor, using the sun C 
	compiler.  If you have the gnu C compiler, uncomment the other
	set of CFLAGS and the definition of gcc as the C compiler.

	You can expect much faster run times using gcc.  I have hacked in
	some assembler macros so it uses the 68881 for square roots inline,
	rather than calling the library function.  If you don't have gcc
	and are running on a sun, I urge you to get it.

3.	Type make.  It should compile.

4.	To test, try running it on the "balls.nff" file. 

		balls -i balls.nff -o balls.pic -r 100 -t
	
5.	To display the image, you need to hack a filter to change it into
	a format your display device can understand.  The format is simple
	and described in the README.  Alternatively, you could ftp an 
	appropriate filter from drizzle.cs.uoregon.edu, where I try to keep
	an archive of filters that people have sent to me.
