Here is a short example of what i 've got :
package
{
import away3d.containers.ObjectContainer3D;
import away3d.containers.View3D;
import away3d.core.base.Vertex;
import away3d.core.math.Number3D;
import away3d.geom.Explode;
import away3d.primitives.Plane;
import away3d.primitives.Sphere;
import flash.display.Sprite;
import flash.events.Event;
/**

* @author Ghislain Flandin
*/
public class Main extends View3D
{
public function Main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
x = this.stage.stageWidth / 2;
y = this.stage.stageHeight / 2;
camera.z = -900;
camera.y = 0;
var plane:Plane = new Plane( { width:256, height:91,
segmentsW:8,
segmentsH:7 ,rotationX:90} );
//scene.addChild(plane);
var exploder:Explode = new Explode(true, true);
var exploded:ObjectContainer3D = exploder.apply(plane)
as
ObjectContainer3D;
var containerExploded:ObjectContainer3D = new
ObjectContainer3D();
scene.addChild(containerExploded);
containerExploded.addChild(exploded);
//containerExploded.rotationX = 90;
//use a sphere to position my triangles
var sphere:Sphere = new Sphere( {segmentsW:11,
segmentsH:11, radius:
150} );
//scene.addChild(sphere);
for (var i:int = 0; i < sphere.vertices.length; i+=1)
{
var vertex:Vertex = sphere.vertices[i];
exploded.children[i].x = sphere.vertices[i].x;
exploded.children[i].y = sphere.vertices[i].y;
exploded.children[i].z = sphere.vertices[i].z;
exploded.children[i].lookAt(new Number3D());
}
render();
}
}
}
I hope you could help me !!!
Thanks a lot !
