In a thread, that has rolled into a discussion about Sky Domes, Ajax has offered an awsome free poser sky dome!  I would love to know where his sky domes' texture map got it's distortion?  

My guess was that this was the Distort filter, but Polar coordinates was my best gues.  His answer is that E-On Vue does that it, but I'm also interested in distorting plain photographs.

If you look at my post, dated Sun, Mar 25, 2007 4:25 am(A chrome/blue Angel with a pink squigly,) you can see what I'm getting at.

Could anybody explain what Vue is doing?
