Hi
For a university project we need to make a 3d programme in Java.
And unfortunately, we're not allowed to use the Java3D classes, so we will
have to make either a renderer or a raytracer (or both) in java...
Does anyone know where I can find more information on:
-Simple instructions to make your own raytracer/renderer
-A simple parser (ie: what does a parser need to do? things like bounding
boxes etc)
-Java 3d programming examples. (not using Java3D)

I ask this here because I'm for some time a Pov user and I know there are a
lot of people here with programming knowledge.
The problem is that information is harder to find than I thought...

If people here seem interested, I'll post here more often about our
advancing...

First, a terminology correction: a raytracer *is* a renderer. Anything 
that generates a picture is a renderer. I think you were thinking of the 
difference between scanline rendering and raytracing.

Raytracing info:

Lots of raytracers here:

A parser just needs to read in a file and convert it to an internal 
representation or follow commands in it to create an internal 
representation. It's mainly string manipulation, reading in data from a 
file. If you can't figure out how to make a simple one you probably 
wouldn't understand a detailed explanation.
Bounding boxes don't have anything to do with a parser.

Hmm...can't really help here. You need to be a bit more specific...I'd 
start with a 3D vector class and the other 3D math basics. There's lots 
of this stuff out there.

Heh, an exceptional amount of dead links there, of the links I tried only 
ftp.povray.org and some other ftp site with old POV versions actually 
worked...

Hi Tijmen,
Have a look at this library http://www.cmlab.csie.ntu.edu.tw/~robin/JavaGL/
(This is an openGL bind written in pure Java).
There is an open source raytracer written in Java. I think it is called
Raja. Just type that in Google and see if you can find it.

Hope that helps.

All the best

Fidel.
