Nest3D is a light weight and flexible 3D engine. It is simple to use and has some features as mesh control, light management (e.g. ambient or directional) and shaders abstraction.

Sample

package  
{
	import flash.display.Sprite;
	import flash.display.StageAlign;
	import flash.display.StageScaleMode;
	import flash.events.Event;
	import flash.events.KeyboardEvent;

	import nest.object.Container3D;
	import nest.view.Camera3D;
	import nest.view.ViewPort;

	public class DemoBase extends Sprite {

		protected var keys:Array = new Array();

		protected var view:ViewPort;
		protected var camera:Camera3D;
		protected var scene:Container3D;

		protected var controller:ObjectController;

		protected var speed:Number = 2;

		public function DemoBase() {
			stage.scaleMode = StageScaleMode.NO_SCALE;
			stage.align = StageAlign.TOP_LEFT;
			stage.frameRate = 60;

			camera = new Camera3D();
			scene = new Container3D();
			view = new ViewPort(800, 600, stage.stage3Ds[0], camera, scene);

			controller = new ObjectController(camera, stage);
			addChild(view.diagram);
			view.addEventListener(Event.CONTEXT3D_CREATE, onContext3DCreated);
		}

		private function onContext3DCreated(e:Event):void {
			stage.addEventListener(Event.RESIZE, onResize);
			stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);
			stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);
			stage.addEventListener(Event.ENTER_FRAME, onEnterFrame);
		}

		private function onKeyDown(e:KeyboardEvent):void {
			keys[e.keyCode] = true;
		}

		private function onKeyUp(e:KeyboardEvent):void {
			keys[e.keyCode] = false;
		}

		private function onResize(e:Event):void {
			view.width = stage.stageWidth;
			view.height = stage.stageHeight;
		}

		protected function onEnterFrame(e:Event):void {
			if (keys[87]) camera.moveForward(speed);
			if (keys[83]) camera.moveForward( -speed);
			if (keys[68]) camera.moveSideways(speed);
			if (keys[65]) camera.moveSideways( -speed);

			view.calculate();
			view.diagram.message = "Objects: " + view.numObjects + "\nTriangles: " + view.numTriangles + "\nVertices: " + view.numVertices;
		}
