Been bumming around this news group for the past year or so and
experimenting with POV / Moray on and off again (more so on again
recently). Attached are two studies that I put myself through in order
to try and see the relationship between various aspects of the program.
These are sort of "End of chapter summaries". Got a couple of things in
the pipeline that are due to be finished is a week or so.......actual
scenes, not just spheres and boxes.
These are all done in POVRay 3.1.
I am somewhat old school, and I am actually using POV 3.1 ported to OS/2
to do a lot of the experimental learning work. Most of the final stuff
is done with 3.1 for Windows on a Win2000 machine.

Well not bad, since this scene is simple - how about some effects like area
light, photons, maybe radiosity, to show power of POV ?
and image is IMHO to strongly compressed

Since he is using 3.1, he doesn't have photons and the radiosity is much
worse. And I don't see why area lights, radiosity, or photons would have
any place in a shape demo scene.
I would suggest switching to POV 3.5 and making the text labels thinner
back to front to make them easier to read. A more complex shape would
make a better mesh demo, and there are plenty of other primitives to
play with. You could make several dozen examples of isosurfaces though...
> and image is IMHO to strongly compressed
It is fine just for a preview of the scenes. This isn't an IRTC entry...

area_light - soft shadows
photons - reflections from few of this shapes
I write _maybe_ radiosity because imho it's effect will not be nottacible
(unles i.e. changing scene to indor

here I ofcourse agree

I didn't see that in your message.

And slower rendering, with no benefit to the demonstration of the shapes
themselves.

But still no help at displaying the shapes. These are "shape samplers".

The improved lighting radiosity gives would make the shapes easier to
see, but would slow things down, and for a scene this simple a few
lighting tricks would work better.

Bare in mind that when these were done, POV 3.5 was still a beta
test......these were only mean to be a sampler of all the shapes in the first
chapter of the POV tutorial. I did them over 8 months ago. Only now getting
into textures......advanced features are still to come down the road. Want to
learn more about Macros and textures at this point.
But regardless I appreciate all the input. Rest assured I have moved on a bit
from these samples......will post some more in the near future.
