I’ve posted a cubic panorama example in the Sandy forum. If you haven’t seen the announcement yet, this awesome ActionScript 2.0 3D package has just released version 0.2. It’s early days yet for Sandy but already things are very impressive. Check out the features, the source, and the forum at Sandy’s Blog.

A note about texture mapping in Flash. I didn’t go into detail about the transformation-matrix method of texture mapping in my article Prospects for Immersive Panoramas in Flash. The idea is that since a single Matrix cannot perform a 3D perspective transformation, we implement it by slicing the texture into smaller pieces (generally triangles) and doing a matrix transformation on each of them. So there’s a tradeoff: the more pieces we cut the texture into, the better the result approximates the true perspective transformation, and the slower our movie runs. This is how Sandy does it, and you can see the technique abstracted into a standalone class by Thomas Pfeiffer here: DistortImage. This class gives you Photoshop-style free transform in Flash.
