Black Hole Simulations: Data Library
Download BH1.ROT size: 58,160 bytes After trying out the amazing PC version of Rotate (from
the brainworks of Marijke van Gans), I was compelled to convert my old
DanCAD data files to ones that could be used by Rotate. This was the first
one, and is simply monochromatic. These .ROT files can be used with either
the PC or Mac versions of Rotater. I personally have even tried them on
a clunky 286 and found that they still work quite well.
Download BH2.ROT size: 89,041 bytes Being displeased by the monochromaticy of my first Rotater
version of my BH sim, I went back and added some arbitrary color. This
file is slightly glitched, but, that's okay.
Download SWALLOW.ROT size: 235,576 bytes I had been trying to simulate what the paths of particles
falling into a black hole would look like for months, but could never quite
get the program to work right. Well, on 3/15/97 at about 2:30 in the morning
(for some strange reason I do my best work in the a.m.) I finally got rid
of the glitches. And this is the .ROT file generated by that very simulation.
Download ACCRET1.ROT size: 96,242 bytes Singularity generated accretion disk w/ gravitational
redshift. This one does not have any polar jets to allow greater freedom
for browsing the interior of the disk. (Because the jets push out the viewpoint.)
Dowload ACCRET2.ROT size: 101,094 bytes Singularity generated accretion disk w/ gravitational
redshift and polar jets. Polar jets left in as unconnected dots because
the generated image was too confusing and "busy" with them connected.
Download the Animation: BH1.ZIP size: 71.266 bytes The animation was created on my old XT. I wrote a program
in C that computed the XYZ coordinates and saved them to an ASCII file.
Then I used DanCAD 3D (an old CAD program) to animate the images into what
you see here.
If it is run on a newer system then it will have to be slowed down. Simply
press "S" for speed or "D" for delay after the program
starts to adjust the frame delay.
What you will see is an embedded diagram representation of the gravitational
curvature of space surrounding a massive black hole with steady mass and
spin velocity. I used such a black hole to make the equations simpler for
my XT (and for me as well!)
Download BH-VAR.ZIP size: 110,162 bytes Alright, this is pretty useless. It's generated by the
equations you get when you remove just about everything that's important
from the original Black Hole equations. But it is a nifty little diversion.
You'll need to slow this one down just like the BH1.ZIP file (see above.)
