Hi all...
Some time back, I had the idea that one could implement progressive
refinement for POVRay -- something like anti-aliasing for larger pixels.
Sombody else suggested in some news group that it would be nice to use
the mouse to manually select regions to be drawn.
Yesterday, I sat down and wrote a patch which does both these things.
The final image will look just as it does with normal povray because
all pixels are traced in the end. However, the patch enables you to
see the important things earlier during rendering. And: it has little
overhead.
See description and example scene (Alex Kluchikov's isosurface) here:
http://www.cip.physik.uni-muenchen.de/~wwieser/render/povray/prt-patch/
In case somebody is interested in porting it to windows/mac, please
contact me.
Any feedback/comments is appreciated.
Regards,
Wolfgang

Interesting idea, it might be a good idea to try the effect on radiosity
scenes if this method is used instead of the pretrace.

I'd like to see this included with a futute version of POV-Ray.... or
perhaps one of the conglomerate patches.

For somebody who has a clue about radiosity code, it should be
fairly trivial to test it.

Me too. Seems very useful for test rendering.
Very nifty. :)
