Math for dummies

Hi everybody,
I have a question for Math champions…which i’m not obviously.
I want to make a 3d carrousel, classic stuff. I won’t be able to explain what i want so i uploaded 2 pictures. The first picture attached is what you can usually see and the second one is the effect i want…a little bit more 3d. Hope you’ll understand what i mean.
For now here’s the code i use onEnterFrame :


    this._x = Math.cos(this.angle) * radiusX + centerX;
    this._y = Math.sin(this.angle) * radiusY + centerY;
    var s = (this._y - perspective) /(centerY+radiusY-perspective);
    this._xscale = this._yscale = s*100;
    this.angle += this._parent.speed;
    this.swapDepths(Math.round(this._xscale) + 100);
    blur.blurX = Math.round(Math.sin(this.angle - Math.PI) * 10);
   blur.blurY = Math.round(Math.sin(this.angle - Math.PI) * 10);
   this.filters = [blur];

Thank’s for the one who can help me a little bit.

Yeah i know, i’m just not too comfortable with AS3 yet and a bit lazy do to it with papervision. I guess i’ll have to look at that. Thank’s anyway for your help.

Why not look at senocular’s excellent 3D article at http://www.kirupa.com/developer/actionscript/camera_panning.htm, that has a example with images in a carousel which is what you want.
It’s a good read if you want to understand the basic concepts behind it and just don’t want to use a existing engine.
Heres a link to that specific fla, hope it helps you some.
