	The POVRAY raytracer
	====================

 This program is essentially POVRAY 3.0 with my own simple
 FRONT END AND OUTPUT for RGB,PICT & TIFF formats.  This is
 only for our own specific local use and NOT distribution.
 A number of people have had problems compiling Version 3 on
 SG Irix, therefore I will let people use this temporily. HOWEVER
 YOU SHOULD OBTAIN THE OFFICIAL POVRAY DISTRIBUTION FROM
 THE POVRAY WEB SITE (http://www.povray.org). All published
 images rendered using this program must acknowledge POVRAY e.g.
 "... image rendered using POVRAY (http://www.povray.org) ...".

There are 2 versions of the povray raytracer here:

 povray-bmm		this supports output to rgb,pict,targa,tiff
 povray-bmm-notiff	as above, but no tiff support

If you run povray-bmm and get the message:

 "... rld: Fatal Error: cannot successfully map soname 'libiflTIFF.do..."

then use povray-bmm-notiff. The only difference between the two
is that povray-bmm-notiff cannot save in tiff format (obviously!).

To save data for these programs from PREPI, use the following:

	DATA > EXPORT DATA FOR RAYTRACING/CAD > POV-RAY (VERSION 3)

This option creates an input file for povray. If a user specifies a file name,
say, protein.ray, then program will also automatically create a file called
protein.ray.par. The latter contains user editable parameters for fine
tuning. See the *.par file for comments.

Simply type the program name (povray-bmm or povray-bmm-notiff)
(without parameters) to get help.

PLEASE READ THE COPYRIGHT, HELP INFORMATION by simply typing the
program name without any parameters.

Please remember that the ray tracer (povray) is the work of the
POVRAY team and not me ! Any problems with the program front end
are down to me and NOT the POVRAY team. If images are rendered using 
povray-bmm, then you must give credit to the POVRAY ray tracer
(http://www.povray.org) and NOT my simple and personal hacked
version of it !
