Spherical Grids of Different Radii
Hi All,I am trying to make spherical grids of varying radii to illustrate the different ways astronomers measure distances. I found the measurement grids and they are very nice and helpful, but I would like to nest the spheres like an onion to help students visualize better. How do I make new ones?

Hi,
You can generate a custom module to use for this. I attached a module here that draws two spheres, 1000 LY and 10 LY. You can split it into multiple mod files if you like separate GUI entries for each, but I added just two spheres in the .speck file. The declaration for this (in the .speck file) is like this:
0 0 0 ellipsoid -s wire -c 1 -r 306.6 -n 36,19
"-r" is followed by the radius of the sphere in parsecs in this case (since the object is in the Milkyway scene).
"-n" is followed by the number of segments in the wire sphere
Hope this helps you out,
