If you can export the data as a tab-delimited text file, it should be very
straight forward for a script to parse the data and convert it to xyz space
(once you determine a suitable MPC-to-pixel scale factor).

(script?) Just
in test form – volunteers are being recruited to populate it. Here’s the data.
The three distance (MPC or megaparsec) is due to lack of agreement. I’m thinking
of averaging them.

[mailto:debberts@comcast.net] 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? Dan From: Stephen van

(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

On Behalf Of Phil 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

working on the 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.
