If l used one of the newer 3-D video cards - Creative Lab's
Voodoo for instance would this significantly improve rendering time and/or
quality ? I realise that these cards are manufactured for gaming but could
they work or is it worth buying a decent PCI SVGA card ?

  It might make your images look prettier but it will have
no effect at all on your rendering time. The reason for
this is because Pov uses very complex mathmatical
calculations that simply take a lot of CPU power to
process. The video card on the other hand is a fast,
almost real time device. It just sits there, waiting on
your CPU to finish what it's doing, before it passes
on a little more of the image to be displayed.

Ken,

Thanx - so it would be better to get a decent 4Mb card and do the 16 Million
color thing :) ?

  If your card doesn't support 16 M colors now you should see a
great improvement. 4 meg cards are good as far as I am concerned.
The only reason you might consider going for a card with more
memory and active 3d support is if you plan on viewing fast gaming
videos and large mpg movies.
    The card you mentioned earlier I believe has pretty good specs
for live/movie quality video.
    If your really going to get into raytracing for a while buy
the lesser card and invest the balance of your money on either
a faster CPU or add to your system memory.
    If you try to render some of the more memory intensive
scenes, and your system doesn't have enough memory, you
can slow down the render time quite a bit, because the system
spend time writing out to your hard drive.
    Most people are now recommending 64 megs of memory
for raytracing and personally I think 128 megs is a lot more
comfortable.
    Having said that I will probably get flamed by the people
that are still running on 16 meg systems.
   Oh well !

Won't do you much of any good. Most 3D accelerator cards simply
manipulate pre-rendered textures at high speed. They can blend, twist,
warp and mutilate the images sent to them, but they can't do any of the
computational expensive raytracing that povray does. Entirely difference
thing.

Best thing to do (for povray) is probably get a good cheap matrox
millennium or like-grade 2d card.

I realize this message is very old, and this poor consumer has probably
wasted a lot of money on a Voodoo card already, but I can't help but wonder
why no one thought of the fact:
A Voodoo/VoodooII card can not run in a window! This means it will have
absolutely NO affect on POV-Ray, which is why it works only for games, it
will not speed up, make prettier or otherwise, in any way, shape or form
help you to buy a voodoo card, invest in another 8M card (I'm selling a
FireGL Pro 1000 8M AGP :) but don't go for the Voodoo card, unless you want
the games.

  A 3D-card will have absolutely no affect on povray no matter if it can
or cannot run in a window. Povray is not a scanline renderer, but a
raytracer. You can't raytrace with a 3D-card.
