Physical simulation of the space engine

36696 I'm sure you've looked at Kip Thorne's paper on rendering the Kerr black hole for the movie Interstellar And for the movie they still settled on a similar rendering technique to what SE uses, non-Kerr and nonrotating. I believe, according to Kip Thorne's book "The Science of Interstellar...

Physical simulation of the space engine

36684 I agree that Kerr would be very difficult (if not impossible) This is something I have gone into quite a bit and tried figuring out with Duke but optimizing the Kerr metric requires assumptions for angles outside of equatorial and this gets very complex very fast, almost as complex as the met...

Physical simulation of the space engine

It is a very good approximation based on general relativity solution :) More specifically, it is approximation of Schwarzschild black hole potential  by Paczynski and Wiita (1980): F = -G * M / (R - Rg) 2 It is not a Kerr metric approximation, so spin is ignored. We still didn't find easy to implem...

Physical simulation of the space engine

I have a question regarding some of the features in SpaceEngine.  The gravitational lensing around black holes looks spectacular!  Is the effect solved using GR (specifically Schwarzschild Spacetime) or is it just a very good approximation?  I imagine it isn't a Kerr solution as the shape of lensing...
