Post subject:  Black Hole Visualization

A scientific level simulation of the various distortions in the stellar sky effected by a Black Hole has been coded by Thomas Müller/Daniel Weiskopf@ Institut für Visualisierung und Interaktive Systeme Stuttgart/Germany.

The underlying scientific publication is here:
T. Müller, D. Weiskopf, Distortion of the stellar sky by a Schwarzschild black hole,
American Journal of Physics 78, 204-214 (2010).
DOI: 10.1119/1.3258282

The corresponding openSource program is in C++, using openGL for the 3D renderings.

http://www.vis.uni-stuttgart.de/~muelleta/IntBH/

The code may be downloaded for Linux and for Windows
from Thomas Müller's above homepage.

Here are thre great videos (.MP4) from the simulation that provide a strikingly good visualization of the strange distortion phenomena in different configurations of the observer relative to the Black Hole:

+++++++++++++++++++++++++++++++
1) Free fall starting with zero velocity from rObs/rs = 5.0 (7.4MB)
http://www.vis.uni-stuttgart.de/~muelle ... 00x600.mp4

2) The observer quasistatically approaches the black hole. (6 mb)
http://www.vis.uni-stuttgart.de/~muelle ... 00x600.mp4

3) The observer is rotating around the Schwarzschild black hole on the fixed radius rObs/rs = 5.0 (15 mb)
http://www.vis.uni-stuttgart.de/~muelle ... 00x600.mp4
+++++++++++++++++++++++++++++++

Since the format size is large (1200 x600) you might want to first download the videos locally before playing them. I can get a very smooth display online using the vlc (cross-platform) player.

Stunning! Any application of this code for Celestia? Euhh... Is Celestia still alive btw?

Yes, indeed. It's not only nice it's also correct ;-) I am certainly planning to include BH visualization into Celestia.Sci. While there are BH add-ons (Cham) already, the proper distortions of space-time cannot be implemented at the add-on level.

Cheers,
Fridger

Sounds like fun. Expecting...
