I had to do an experiments in my physics class a few months back. That
was before Nathan Kopp's patch came out and as this experiment is about
refraction/reflection, I couldn't simulate it in pov. However, thanks to
Nathan (thanks, Nathan) I have been able to reproduce the exact
experiment using POV!
This image took 7 minutes to render, and was done with some basic help
from Moray for the objects and textures.

Proving that pov has the potential to do more than just make
pretty pictures of space ships.
Enter the era of scientific visualazation.

Why couldn't you do this without the patch?

I don't know what grade you're in, but if I were you, I'd print it out
and show it to my teacher. Probably get some Extra Credit :-)

I'd like a few of those extra-credit points. ;-)
Actually, I am getting a grade for this project (since I'm doing it as
a directed study for my CS degree).

How? The light is perturbed according to the refraction of the glass
half-moon and is actually going "through" AND reflecting off of it
instead of just casting a shadow and fake caustic as unpatched POV-Ray
does. Notice the perpendicular light artifacts either side the glass.

Hi Lewis,
I've been playing with this patch for a few days now, but it hadn't
occured to me to use it quite this way ...
Anyhow, there is one extra level of refinement you can use with
Nathan's patch - chromatic dispersion of the light. I've attached a
quick render with similar geometries to your picture, but with the light
source set up with a colour spectrum and dispersion on the half
cylinder.
The code for setting up the light source colour spectrum is still a
little experimental, but I could post it if there is any interest.
Bye for now,
Mike Andrews.

Mike
It looks as though there might be light come out of that semi
cylinder object, have you tryed putting a solid object above this
object to see if that is actually happening.
