how do you use Loader3DS?

are there any other model formats likely in the near future?

thanks for your help.

--Spencer

It depends on a requests... probably it is a good idea to create voting on a formats?

can you provide an example of using th loader?

Yes, we'll provide importing tutorial this week.

Here how I do so:

package {
	import alternativa.engine3d.loaders.Loader3DS;	
	import alternativa.engine3d.controllers.CameraController;
	import alternativa.engine3d.core.Camera3D;
	import alternativa.engine3d.core.Object3D;
	import alternativa.engine3d.core.Scene3D;
	import alternativa.engine3d.display.View;
	import alternativa.utils.FPS;
	
	import flash.display.Sprite;
	import flash.display.StageAlign;
	import flash.display.StageScaleMode;
	import flash.events.Event;

[SWF(backgroundColor="#000000", frameRate="100", width="320", height="240")]

public class TestLoader3DS extends Sprite {

private var scene:Scene3D;
		private var view:View;
		private var camera:Camera3D;
		private var cameraController:CameraController;
		//private var house:Object3D;
		
		private var loader : Loader3DS;

public function TestLoader3DS() {
			stage.scaleMode = StageScaleMode.NO_SCALE;
			stage.align = StageAlign.TOP_LEFT;
			
			// Создание сцены
			scene = new Scene3D();
			scene.root = new Object3D();
			//house = new TexturedHouse();
			//scene.root.addChild(house);

loader = new Loader3DS ();
			loader.load("models/model.3DS");
			loader.addEventListener(Event.COMPLETE, onLoad);
			
			//scene.root.addChild( loader.content );
			
			
			// Добавление камеры и области вывода
			camera = new Camera3D();
			camera.x = 130;
			camera.y = -300;
			camera.z = 130;
			scene.root.addChild(camera);
			
			view = new View();
			addChild(view);
			view.camera = camera;

// Подключение контроллера камеры
			cameraController = new CameraController(stage);
			cameraController.camera = camera;
			
			//cameraController.lookAt(house.coords);
			
			cameraController.setDefaultBindings();
			cameraController.checkCollisions = true;
			cameraController.collisionRadius = 20;
			cameraController.speed = 200;
			cameraController.controlsEnabled = true;
			
			// Запуск счётчика кадров
			FPS.init(stage);

stage.addEventListener(Event.RESIZE, onResize);
			stage.addEventListener(Event.ENTER_FRAME, onEnterFrame);
			onResize(null);
		}
		
		private function onLoad(e : Event) : void {
			
			
			scene.root.addChild( loader.content );
			cameraController.lookAt( scene.root.coords );
			
		}

private function onResize(e:Event):void {
			view.width = stage.stageWidth;
			view.height = stage.stageHeight;
		}
		
		private function onEnterFrame(e:Event):void {
			// Обработка пользовательского ввода 
			cameraController.processInput();
			// Расчёт сцены
			scene.calculate();
		}
	}
}

In 76-77 lines is good to insert vertex/face optimization with MeshUtils.
I use recursive method to do optimization through object hierarchy.

how does this affect vertices order and relation to faces/uvs? could you explain in-depth what exactly it does? if I am going to, for example, tween the vertices, I need complete idea of mesh organization.

makc, this will be explained in "Importing models" tutorial which is coming soon.

Loader3D works very fine !

So i add your code for optimization, but with a little scene 3D, I got 16 fps.

So it's so bad compared with yours demos !

you can see it here : http://lab.tomysnockers.net/ville3D/Main.html

Maybe there is a secret ?

i'm impatient of your tutorial !

Thomas, the secret is

Perpective correction working much faster on low quality.
You can change quality only on movement as we made in demos.

Also, you can change texture precision on movement.
Don't forget to make a release build (in Flex Builder: Project -> Export Release Build...).
Debug version works by 20-30% slower.

Thomas, can you get me sources of your example?

it's the same code that Андрей Жуков said at the top.

but how realise walking on the map?

namely, cameraController.processInput ();
