Papervision Plane Rotation Lag

programming flash
1

Heya

Im doing a website for a client, stumbled upon a sought of problem in my code.

The website so far has flower petals floating from the top of the stage, with like perlin and bend as3mod modifier to it to give it that nice floating feel (and smooth rotation). The only thing is that whenever the plane rotates to like 0 where all you see is like a slither my whole computer system stops for about 5 seconds and then goes back to floating. Now i know this is not my computer because i viewed http://www.verbatim.jp/senshuken/ which is a high intensity papervision site and my computer runs that fine, so obviously ive made a **** up in my code!! Excuse the french!

here is my code

these are a few lines in the timeline to load and implement the class:
[COLOR=“silver”]//-------------------------[/COLOR]
import PetalClass;
var wind:Number = Math.random();

[COLOR=“Silver”]//PetalClass(plane width, plane height, x, y, z, velocity, wind)[/COLOR]
var rosePetal:PetalClass = new PetalClass(258, 300, 0, 500, 500, 1, wind);
var material:RosePetal = new RosePetal();
rosePetal.createSides(material);
addChild(rosePetal);

PS. the RosePetal is an item in the library!

And here is the class file:

i would be greatly appreciated if you experts could give some insight or label the stuff i did wrong (its highly possible!!)
