render dots or texture?

michelle-aubrecht commented 12 years ago

you've been busy! I'm not sure what all this means, but will look at it soon. I'm at my brother's now and can't take time until tomorrow morning.

Looks like a great start.

ellemenno commented 12 years ago

no, we need a spherical texture map. i was thinking of using this one: http://paulbourke.net/miscellaneous/starfield/

This is the image I have: http://www.eso.org/public/images/eso0932a/ Bill and I identified the path for the milky way (shown by a green or blue line on the star map I sent Tuesday this week.) I also got permission from Lars at ESO to use it. Thanks for the link about how to work with the image file!
