Papervision3D with AS3Dmod Hello World Example
Bartek Drozdz is a Flash3D rock star. He put together an as3 library called AS3Dmod which allows you to modify the shape of your 3d objects using a modifier stack. This example is a Hello World intro to using the Bend modifier.
package { import com.as3dmod.ModifierStack; import com.as3dmod.modifiers.Bend; import com.as3dmod.plugins.pv3d.LibraryPv3d; import flash.events.Event; import org.papervision3d.materials.WireframeMaterial; import org.papervision3d.objects.primitives.Plane; import org.papervision3d.view.BasicView; [SWF(width="640", height="480", backgroundColor="#000000", frameRate="60")] public class Papervision3DwithAS3Dmod extends BasicView { private var plane:Plane; private var modifierStack:ModifierStack; private var bend:Bend; public function Papervision3DwithAS3Dmod() { var wireframeMaterial:WireframeMaterial = new WireframeMaterial(0xcc0000); wireframeMaterial.doubleSided = true; plane = new Plane(wireframeMaterial, 800, 800, 20, 20); plane.rotationX = 45; plane.rotationY = 45; modifierStack = new ModifierStack(new LibraryPv3d(), plane); bend = new Bend(); modifierStack.addModifier(bend); scene.addChild(plane); startRendering(); } override protected function onRenderTick(event:Event=null):void { plane.rotationY += (viewport.containerSprite.mouseX - plane.rotationY) * .1; bend.force += (viewport.containerSprite.mouseY / 100 - bend.force) * .3; modifierStack.apply(); renderer.renderScene(scene, camera, viewport); } } }
