Switching from Planes to Sprite3D in Away3DLite seems to have given me
some pretty dramatic speed increases. Since my particles don't have to
rotate this is a nice boost. Below is my updated quick 'n dirty test:
*** Away3DLite 1.0 ***
package
{
import away3dlite.containers.Scene3D;
import away3dlite.containers.View3D;
import away3dlite.primitives.Plane;
import away3dlite.sprites.Sprite3D;
import com.greensock.TweenLite;
import com.gskinner.utils.Rnd;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.TimerEvent;
import flash.utils.Timer;
import net.hires.debug.Stats;
[SWF(width="800", height="600", frameRate="24")]
public class Main extends Sprite
{
protected var _view : View3D;
protected var _timer : Timer;
public function Main()
{
_createView();
_createScene();
_createCamera();
}
protected function _createView() : void
{
// Create view and add it to the stage
_view = new View3D();
addChild(_view);
//Relocate center point of view to the center of an
800x600 stage.
_view.x = 400;
_view.y = 300;
//call the view render method on every frame of the
Flash movie
addEventListener(Event.ENTER_FRAME, _onEnterFrame);
}
protected function _createScene() : void
{
// Create a new scene containing a trident and two cubes
var scene : Scene3D = new Scene3D();
var l:int = 1000;
for(var i:int = 0; i<l; ++i)
{
var particle:Sprite3D = new Sprite3D();
particle.width = 8;
particle.height = 8;
particle.x = Rnd.sign()*(400*Math.random());
particle.y = Rnd.sign()*(300*Math.random());
scene.addSprite(particle);
}
//Assign the new scene to the view
_view.scene = scene;
addChild(new Stats());
_timer = new Timer(50);
_timer.addEventListener(TimerEvent.TIMER, _onTick);
_timer.start();
}
protected function _createCamera() : void
{
}
protected function _onEnterFrame(ev : Event) : void
{
_view.render();
}
protected function _onTick(ev : Event) : void
{
TweenLite.to(_view.scene.sprites[int(499*Math.random())], 1,
{x:Rnd.sign()*(400*Math.random()), y:
Rnd.sign()*(300*Math.random())});
TweenLite.to(_view.scene.sprites[int(499*Math.random())], 1,
{x:Rnd.sign()*(400*Math.random()), y:
Rnd.sign()*(300*Math.random())});
TweenLite.to(_view.scene.sprites[int(499*Math.random())], 1,
{x:Rnd.sign()*(400*Math.random()), y:
Rnd.sign()*(300*Math.random())});
TweenLite.to(_view.scene.sprites[int(499*Math.random())], 1,
{x:Rnd.sign()*(400*Math.random()), y:
Rnd.sign()*(300*Math.random())});
}
}
}
