Multiple view port working? Software: Away3D 4.x

forest, Newbie Posted: 06 August 2014 05:34 PM Total Posts: 6 Hi there. I’m testing en example with four view ports of the same scene: http://www.flashmagazine.com/tutorials/detail/away3d_4_basics_-_the_view_and_the_scene/ on a Galaxy Note2. Only the top left view port shows. All four view ports show on desktop Please help Thanks

Take a look in the Stage3DProxy class and the use in the docs. So you may change the view instances with: view.shareContext= true; view.stage3DProxy= yourStage3DProxy;
forest, Newbie Posted: 30 September 2014 02:58 AM Total Posts: 6 [ # 2 ] Thanks. I tried the sharedContext but had quite a few roadblocks few weeks ago: 1) picking throws exception 2) I setup context3d.setRenderToTexture() to some texture. But view.render() eventually sets render target to the default back buffer again. And frankly, I don’t know how to correctly replicate Opengl’s glViewPort() in stage3d. For stereo rendering, I did something akin to context3d.configureBackBuffer( myStage.stageWidth/2, myStage.stageHeight); myStage.x=0; view.render(); myStage.x = myStage.stageWidth/2; view.render(); But only one view.render() call produces visible results.

Anyway, if you intent to render multiple views/scenes, you need multiple views instances, all sharing the same Stage3D (and its backbuffer, etc). So just create 2 view3d instances, share the same proxy, and place them side-by-side in the flash stage. In the proxy enterframe, just render both. The stage3D is like an empty canvas, where you just go rendering things layer by layer. Here is a little test: package { import away3d.containers.View3D; import away3d.core.managers.Stage3DManager; import away3d.core.managers.Stage3DProxy; import away3d.events.Stage3DEvent; import away3d.primitives.WireframeCube; import away3d.primitives.WireframePrimitiveBase; import away3d.primitives.WireframeTetrahedron; import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; [SWF(backgroundColor="#0055aa", frameRate="30", width="1024", height="720")] public class MultiViewTester extends Sprite { private var leftView : View3D; private var rightView : View3D; private var stage3DProxy : Stage3DProxy; private const cube : WireframePrimitiveBase= new WireframeCube(100,100,100,0xff0000); private const tetra : WireframePrimitiveBase= new WireframeTetrahedron(100,100,0x00ff00); // Construtor public function MultiViewTester() { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; var stage3DManager : Stage3DManager = Stage3DManager.getInstance(stage); stage3DProxy = stage3DManager.getFreeStage3DProxy(); stage3DProxy.color= 0x004080; stage3DProxy.addEventListener(Stage3DEvent.CONTEXT3D_CREATED, onContextCreated); } private function onContextCreated(event : Stage3DEvent) : void { leftView= new View3D(); leftView.shareContext = true; leftView.stage3DProxy = stage3DProxy; leftView.width= stage.stageWidth * .5; leftView.scene.addChild(cube); addChild(leftView); rightView= new View3D(); rightView.shareContext = true; rightView.stage3DProxy = stage3DProxy; rightView.x= rightView.width= stage.stageWidth * .5; rightView.scene.addChild(tetra); addChild(rightView); stage3DProxy.addEventListener(Event.ENTER_FRAME, onFrame); } private function onFrame(event : Event) : void { cube.rotationX+= 2; cube.rotationZ-= 2; tetra.rotationX-= 2; tetra.rotationY+= 2; leftView.render(); rightView.render(); } } }
