Are you looking at doing something like:
The first one is using Shockwave 3D and making the image a map on a cylinder. The second one is a 2D image that loops, which is what I kind of understood yours as being.
There is a Director tutorial that explains the idea at:
As you'll see at teh bottom of the above page, it was inspired by the work of Jim Collins, who created the first 2 URL I put in this message.
There is another demo that does example 2 exactly. I thought it was on Director Online but can't seem to find it. I have a demo Director file if you'd like to see it.
Your links pointed to something more sophisticated than what I was trying to do. I will definately be looking at the tutorial you linked to.
As you'll see in the tutorial, in order to create the seamless loop, you need to repeat part of the graphic in the image. If you want me to send you a demo Director movie, send me an email to firstname.lastname@example.org.
