What form is the data in now? The script could certainly do the conversion
from right ascension , declination and
distance. Then I think all you need is to pick a scale factor for the distance
to fit everything into a AE-sized world. How much data is there?

(script?) Phil, Not
in a huge rush and that would certainly get you listed in the film’s credits –
thanks so much for the offer. Let me work on the Excel side of things (not that
I’m genius there either but it should be possible) to get it sorted
out. I
am wondering about the multiplier – wonder if it needs to be truly logarithmic
giving the size of the universe. The observable universe is 46 billion light
years across, the average galaxy (e.g. ours) is 100,000 light years, that’s a
ratio of 460,000 : 1. Any
idea of maximum XYZ values in AE? stephen

Spitler If you can get the data into a spreadsheet into X,Y,Z
columns, it would be easy enough to have a script read each row of x,y,z and
apply that to the position of a layer. I have done a similar thing taking camera data from a motion
control rig into AE. If you are not in a huge rush, I could write the script for
you once you give me a sample of the data. You will probably need some kind of multiplier in there to
make the values fit within you AE world. Phil Phil

Big Bang section of the film. A local community college is researching celestial
objects that have been imaged. They provide two pieces of data – the spherical
position via a value for right ascension & declination. And a distance in
megaparsecs. I need to convert
this into a manageable form in AE. Obviously, some kind of compensation
for I found this on
converting to XYZ – but the how to create the math to work in AE, I’m not sure
what is the best way: I don’t know if
this should be setup in Excel and then exported into AE, or some kind of script
built – which is probably beyond my admittedly poor scripting
skills.
