Persistence of Vision(tm) Ray Tracer
POV-Ray(tm) Version 3.00
Acorn RISC OS specific ReadMe
I. Introduction
===============
This is a port of POV-Ray V3.00e to the Acorn RISC OS platform. Please read
this document carefully, as it contains information about the differences
to the original unix version of POV-Ray and about future plans, too.
At the moment, it's a very small port of POV-Ray, as it doesn't support any
RISC OS feature like a WIMP front-end or a other display than a text based
that gives you just a vague view of the real image.
II. Filenames
=============
There is one main difference to the unix version: filenames. Unix allows
filenames like 'szene.pov' or 'hellow.c', but RISC OS uses the point as the
filename seperator. The problem is solved like all current C compiler did
it: a filename 'hellow.c' could be used, but it is translated to 'c.hellow'.
So you have to create a directory 'c' and put into it the file 'hellow'.
Look at the different directories including the sample files to see what i
mean.
Even outputs are handled this matter, so take care to have a correct
directory where povray can place it's files.
When you use POV-Ray you don't need to type in the .pov extension for the
input file as it is appended and you mustn't do this for the output
file. E.g.: 'povray +Ipovscn.level1.cantelop +Ocantelop', input file is
'povscn.level1.cantelop.pov' output file is 'cantelop.tga' (for targa).
This translation was the only way to prevent you to rewrite all existing
povray scene files as they include lines like:
#include "colours.inc"
III. Environment Variables
==========================
The ported version of POV-Ray uses the same environment variables as the
unix version. See the documentation or the file !ClickMe for help.
IV. Installation
================
Not much to say about it. Just unpack the archive and edit the povini file
in the ini directory to fit your system. That's it.
V. Memory
==========
You should have at least about 1300K for POV-Ray to run. 4-8MB are
recommended.
VI. Future Plans
================
If there is enough interest, some improvements could be added to POV-Ray:
- WIMP frontend
- real display (Sprite)
- other output formats like Sprite
So please let me know, if you are useing POV-Ray 3.00 and if you would
like some improvements.
