[Papervision3D] Flash CS4 Spherical Panorama (animating uvtData)

[Mikenku]

Intro
Creating a CS4 Panorama has a unique twist - literally! You actually don’t
rotate the primitive but you animate its texture, using the following code
snippet:

public function step(moveU:Number, moveV:Number=0.0):void {
for (var i=0; i<uvtData.length; i+=2) {
uvtData[i++] -= moveU;
uvtData[i] += moveV;
// each loop i increases by 3 because skiping over the t-coordinate
}
}

The uvtData is easily animated just by skipping through correct U or V
values of the uvtData vector and adding a small increment. Click on the

As in the previous Super Prim post, Petri Leskinen’s great work on Pixelero
http://pixelero.wordpress.com/ was key to this creation. He demonstrates an
animated tube which with a little work I was able to turn into this
panorama. The code is encapsulated and very closely resembles the OOP
regimentation of Papervision3D.
