[Papervision3D] Animating camera to target

[xero]

i think you can achieve this w/ interactiveScene3DEvents.

when you click on a plane, you have a function that gets called.
that function takes a parameter of the InteractiveScene3DEvent type. lets
call it "e".

from "e" you can get all kinds of info about the object your
interacting w/ (eg, x/y/z position, rotation, name, material, etc, etc, etc)

i think it would be easy to use the X/Y/Z pos of the plane clicked as a  target
for your camera. just decrease the Z value so the camera will not fly
thought the target plane.

this code is untested!

[code]

function constructor() {
    var thePlane = new Plane(...);
    thePlane.addEventListener(InteractiveScene3DEvent.CLICK, onClick);
    scene.addChild(thePlane);
}
function onClick(e:InteractiveScene3DEvent):void {
    //create a temp object
    var target:DisplayObject3D = new DisplayObject3D();

    //set is positions equal to the clicked object's
    target.x = e.displayObject3D.x;
    target.y = e.displayObject3D.y;
     //offset the z depth
    target.z = e.displayObject3D.z - 300;

    //you can manually move camera position with:
    //cam.copyPosition(target);

    //but honestly, this would look better w/ a tween
    Tweener.addTween(cam, {
          x: target.x,
          y:target.y,
          z:target.z,
          time: 10,
          transision: easeOutSine
     });
}
[code]

like i said, this code is untested (wrote in gmail).
but the core concept is there.

hope that helps!
