BitmapParticleMaterial

The BitmapParticleMaterial class lets you use a bitmap as particle material. The bitmap can be created in two ways:

• A dynamically drawn bitmap

• A loaded bitmap

The next two sections will show an example for each of them. Let's start with a drawn bitmap.

Using a dynamically drawn bitmap as BitmapParticleMaterial

Again we will use the ParticleTemplate class as our starting point. In this example named BitmapParticleMaterialShapeExample, we need to import the BitmapParticleMaterial class.

import org.papervision3d.materials.special.BitmapParticleMaterial;

Add the following code at the top of the init() method to instantiate the Particles class and add it to the scene:

var particles:Particles = new Particles();
scene.addChild(particles);

Add the following inside the for loop:

var triangle:Shape = new Shape();
triangle.graphics.beginFill(Math.random() * 0xFFFFFF);
triangle.graphics.moveTo(0,0);
triangle.graphics.lineTo(20,20);
triangle.graphics.lineTo(40,0);
var bitmapData:BitmapData...
