ok, thanks
here is the demo: http://prologis.win.pl/OverlayTest.swf
I created a class called Overlay and placed it in away3D/overlays
folder
I place it on a standard away3D stage like this: overlay = new
Overlay(view, camera);
the original size of the document is 700x600px (this is important!)
so, whatever you do for checking first make the window display:
700x600 (700 in width)
the away3D scene has a resize function:
private function Resize(evt:Event = null):void {
view.x = this.stage.stageWidth / 2;
view.y = this.stage.stageHeight / 2;
clipping.minX = -this.stage.stageWidth/2;
clipping.minY = -this.stage.stageHeight/2;
clipping.maxX = this.stage.stageWidth/2;
clipping.maxY = this.stage.stageHeight/2;
var te = "stageWidth/stageHeight: " + this.stage.stageWidth + " / " +
this.stage.stageHeight;
_txt.text = te;
EnterFrame();
}
the test swf you see when set at 700x600 make the square perspective
to the scene, but when you resize and actually CHANGE the view.x/
view.y something happens to the overlay object
I checked everything: scale, size, x/y of everything - it is exactly
the same before and after resizing but the square changes its look
here is the Overlay class:
package away3d.overlays
{
import away3d.cameras.*;

import away3d.containers.View3D;

public class Overlay extends Sprite implements IOverlay
{

public function Overlay(v:View3D, c:Camera3D, init:Object =
null)
{
view = v;
camera = c;
flipY.appendScale(1, -1, 1);
overlayContainer = new Sprite();
this.visible = false;
createTestSprite();
}
private function createTestSprite():void {
testSprite = new Sprite();
testSprite.graphics.clear();
testSprite.graphics.beginFill(0xFF0000, 1);
testSprite.graphics.lineStyle(3, 0x000000);
testSprite.graphics.drawRect(-150, -150, 300, 300);
testSprite.graphics.endFill();
setNewSettings();
}
private function setNewSettings():void {
object3D = new Object3D();
object3D.x = 0;
object3D.y = 0;
object3D.z = 400;
view.scene.addChild(object3D);
this.addChild(testSprite);
view.addOverlay(this);
}
public function update():void {
sourceProjection = camera.screen(object3D, new
Vertex(object3D.x,object3D.y,object3D.z));
if(!sourceProjection || sourceProjection.z < 0){
if(this.visible) this.visible = false;
return;
}
if(!this.visible) this.visible = true;
scale = camera.lens.getPerspective(sourceProjection.z);
viewMatrix.identity();
viewMatrix.rawData = camera.viewMatrix.rawData;
viewMatrix.prepend(flipY);
overlayMatrix.identity();
overlayMatrix.prepend(viewMatrix);
overlayMatrix.prepend(object3D.sceneTransform);
scale = camera.lens.getPerspective(sourceProjection.z);
overlayMatrix.appendScale(scale,scale,1);
overlayMatrix.appendTranslation(sourceProjection.x,
sourceProjection.y, 0);
this.transform.matrix3D = overlayMatrix;
}
}
}
I really need help with this, I just have no more ideas what can be
wrong
