There will also be considerable distortion by gravitational effects. Has anyone done an accurate raytracer for the view from inside a BH?


Andrew Hamilton has. There's a crude version of the results at http://casa.colorado.edu/%7Eajsh/schw.shtml 

Nice site! Many thanks for this.

What a pity that with Schwarzschild metric BH you don't get ever to see the singularity despite being consumed by it.

Has anyone done similar similations for inside extreme Kerr metric black holes entering in free fall as a test particle going with the spin and against it?

ISTR the latter case might provide an interesting view of something you are not really supposed to ever see...

I've seen a much more elaborate one, but I don't think it's available
on the Web.  Greg Egan has also done some of this -- see
