Does anyone know of a a version of POVRAY that takes account of the effects
of general relativity?

Also suggestions of any other relativistic raytracers would be appreciated

What sort of applications/scenes are you wanting this for?  I'd imagine most
things (orbits etc.) could be calculated using formulas within your scene
file - and that there wasn't any need for any additions to POV.  Come to
think of it... what extra effects are you hoping for?  If you're wanting the
see something like the bending of light rays under gravity, then I doubt
this would be possible as POV (at least not the official one..) doesn't deal
with light rays/photons in the correct manner.  4D is pretty hard to model
too ;)

I'd imagine POV is meant for and will probably say more for artistic design
than as a virtual laboratory (though it would be good if it was as well ;)

Visit http://math1.uibk.ac.at/~werner/light/  and its links, especially
http://math1.uibk.ac.at/~werner/bh/gvsim.html


Not only animations of what it's like to fall into a black hole, but he had
color dispersion, caustics, scattering media, etc. long before anyone working
on POV-Ray even started on those things.  He also had access to some serious
computing power.

Do you think he'd consider sharing it with me?  ;-)

maybe he wants to speed up slow POV render times (or will relativity just
slow down the fast ones? ) ; )

Also to be noted, the very good free relativist raytracer with sources at
http://www.anu.edu.au/Physics/Searle/ Page title : [Backlight Home - Special
Relativity].

Cheers,
Al.
