   In the examples I created over here I used 3 seperated Renderers for Red, Green and Blue.
   
   
   Adding a Blendmode ("add") to the renderer give's the nice colorfull effect.
   
   Downside for the colorfull effect is that i have to use 3 seperated renderers?
   Or is there a way giving a blendmode to an emitter?
   
   Here's the source code of 1 example
   
   
package {
import flash.display.Loader;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.MouseEvent;
import flash.filters.BlurFilter;
import flash.geom.Rectangle;
import flash.net.URLRequest;
import flash.text.TextField;
import flash.text.TextFormat;

public class RGBBlendDisc1 extends Sprite {
private var w:uint = 400;
private var h:uint = 400;
private var amount:uint = 200;
private var text:TextField;
private var loader:Loader;

public function RGBBlendDisc1(){
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;

createDisc(0xffff0000, 0xffffcc33, new Vector3D(0, 0, 0), new Vector3D(1, 0, 0));
createDisc(0xff00ff00, 0xff33ffcc, new Vector3D(0, 0, 0), new Vector3D(0, 1, 0));
createDisc(0xff0000ff, 0xffcc33ff, new Vector3D(0, 0, 0), new Vector3D(0, 0, 1));
}

private function createDisc(color1:uint, color2:uint, point1:Vector3D, point2:Vector3D):void {
var emitter:Emitter3D = new Emitter3D();
emitter.counter = new Blast( amount );

emitter.addInitializer( new SharedImage( new Dot( 1 ) ) );
emitter.addInitializer( new Position( new DiscZone(point1, point2, 100, 100 ) ) );
emitter.addInitializer( new ColorInit( color1, color2) );
emitter.addAction( new Move() );
emitter.addAction( new GravityWell(5, new Vector3D(0, 0, 0) ) );

var renderer:PixelRenderer = new PixelRenderer( new Rectangle( -200, -200, 400, 400 ), false );
renderer.camera.dolly( -300 );
renderer.camera.lift( 100 );
renderer.camera.target = new Vector3D( 0, 0, 0 );
renderer.camera.orbit(45 * Math.PI / 180);
renderer.addFilter( new BlurFilter( 2, 2, 1 ) );
//renderer.addFilter( new ColorMatrixFilter( [ 1,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0.99,0 ] ) );
renderer.addEmitter( emitter );
renderer.x = w/2;
renderer.y = h/2;
renderer.blendMode = "add";
addChild( renderer );

emitter.position = new Vector3D( 0, 0, 0, 1 );
emitter.start( );

var orbitter:OrbitCamera = new OrbitCamera( stage, renderer.camera );
orbitter.start();
}
}
}

   These examples are looking great. Have you found any bugs yet, or is it all working fine?
   
   Re: blendMode. Flash applies blend modes to display objects, so to separately apply blendModes to each emitter's output they have to use different display objects, hence needing a new renderer for each emitter.
   
   If you use display objects rather than pixels for the particles, you can apply a blend mode to each particle's image and it will be used when drawing the particle, but this means you can't use a pixel renderer - you have to use a bitmap renderer or display object renderer and use a display object of some form for each particle.
   
   I haven't created an initializer to do this, but probably will at some point. I am currently concentrating on the away3d and papervision3d renderers.

   I think i just found one little bug with the explosion action.
   You have to fill in a very large number to get a bit of an explosion
   
   
//emitter.addAction( new Explosion( 10000, new Vector3D(0, 0, 0)));

   
   Thanks for clearing out the blending mode stuff.
   If i have some time i'll dive into it.
   
   Good luck with the papervision3d renderers, really looking forward to it!

   I've fixed the explosion thing in Alpha 2 - An explosion of power 1 should have a visible effect now.
