I was curious to see how light bounces from a parabolic mirror
when it comes from different directions. So I made a parabolic
mirror and then used scattering media and photons to get visible
rays of light. If you follow carefully a ray of one color you'll
get a clear picture about how it bounces around.
Hi!
Nice POVRay experiment! You could place the lasers (light sources) so that
they "shoot" precisely into the focus of the parabola just to check if
everything in the POVRay World works as expected.

Isn't that what he's done with the top 5?

Hi!
Ah, yes You are right, as for the sake of the experiment it does not matter
what feature a beam hits first, the mirror or the focus. These 5 demonstrate
the idea of say radiotelescope, the reversal of it (when you distribute the
guns around the mouth of the mirror) would show the implementation of a
photon engine concept.
I was just curious, and thought it would be nice to see an idea of
interstellar propulsion in operation.

Nice Illustrations, i like them :)
i never got media-photons look right..
i always imagined them looking that way :)
I have one suggestion though, could you make the parabolic mirror
a good amount shallower / the curvature less? Then one could see
the focal point of the mirror better. You could also place a
lightsource at the focal point (or slightly off for comparison) to
see the reverse effect (like a flashlight).

Look in povray.binaries.scene-files for a similar message title, you'll find the
source code.
Looking at the sources in detail is a good way to learn.
