Problem with stage3D and away3D

2017-04-26T07:19:12+00:00

Ok that is so strange it make like 3 hour i try to figure this out. First… everything was working correctly so i don’t know what i change or if i updated to new code for starling or away3d and i dont think so.

I use the standard code to create a stage3DProxy

/**
   * will start the engine
   */
  public function StartUpEngine():void {
 
   // Define a new Stage3DManager for the Stage3D objects
   stage3DManager = Stage3DManager.getInstance(stage);
 
   // Create a new Stage3D proxy to contain the separate views
   stage3DProxy = stage3DManager.getFreeStage3DProxy();
   stage3DProxy.addEventListener(Stage3DEvent.CONTEXT3D_CREATED, onContextCreated);
   stage3DProxy.antiAlias = 8;
   stage3DProxy.color = 0xff0000;
 
  }
 
  private function onContextCreated(event : Stage3DEvent) : void {
 
   stage3DProxy.removeEventListener(Stage3DEvent.CONTEXT3D_CREATED, onContextCreated);
 
   stage3DProxy.width = stage.fullScreenWidth;
   stage3DProxy.height = stage.fullScreenHeight;
 
   //Init everything
   InitAway3D();
   InitStarling();
   InitListeners();
 
  } 

all was working.. now… away3D is working but i can’t get starling to render… it’s clearly there when i trace it.

I do have a enter_frame event that do a nextFrame()

private function InitListeners():void {
    stage3DProxy.addEventListener(Event.ENTER_FRAME, onEnterFrame);
  }
 
  private function onEnterFrame(e:Event):void {
 
   //render starling and away3d
   away3DInstance.render();
   starlingInstance.nextFrame();
 
  } 

all pretty standard and it worked!

if i just disable the proxy and do a normal starling instance it’s working.

i swear all was working yesterday i just don’t get it. i trie dto just disable the away3D and starling still not render. it’s like the proxy wasn’t working but IT WAS working before…

Anyone got a hints ? it make 3 hours i’m searching and i’ve tested every options.

Away3D questions

2017-04-12T09:26:06+00:00

Hi guys, I am starting to work with Away3D and I will have few questions in an upcoming days for those who already worked with it.

Question: Is it possible to decrease the number of polygons on the external model without editing the model in some 3D graphic software? I have bought human model made in 3D Max but it is so complex

Artifacts when change properties of CylinderGeometry?

2016-05-17T21:55:52+00:00

If I create a cylinder geometry by doing
var cyl:CylinderGeometery = new cyl:CylinderGeometery()
cyl.topRadius = 5; // Or any other property change

Then I see the correct shape, but I also see an artifact that looks like a piece of the side of the original cylinder.

But if I pass in all the properties when I create the cylinder, e.g.
var cyl:CylinderGeometery = new cyl:CylinderGeometery(5, etc)

then it renders correctly. Is this a bug, or do I need to do something to clear the geometry before or after I change its properties?
Thanks!

3d renders

“Hi guys,
I have a question. Do you make 3d renders of your projects in-house or use outsource visualization company?”

Strange behavior when calling consecutive transform within an event

2014-04-10T13:58:34+00:00

Basically, you can’t access a sceneTtransform and set an unrelated object.transform within an event…?

private function initCameraListener() : void {
   view.camera.addEventListener(Object3DEvent.SCENETRANSFORM_CHANGED, onCameraChange);
  }

  private function onCameraChange(event : Object3DEvent) : void {
   const camera : Camera3D = (event.target as Camera3D);
   const obj : Object3D = new Object3D();

   // ********************************************************
   // Does nothing, purposely. Just to force a getter call.
   camera.sceneTransform;

   // This affects the camera hover!
   // Comment out this line, or the above one to get the expected result
   obj.transform = new Matrix3D();
   // ********************************************************
  }
  // // // // // // ////////////////////////////////////////// 

I’ve attached a full code for an example of this strange behaviour.

I speculate that it is caused by parallel access of statics consts like Matrix3DUtils.RAW_DATA_CONTAINER and others.

I understand that it optimizes the memory access avoiding constant memory allocation, but it may cause some weird problems when running in asynch codes.

Possible Memory Leak in Away3D OpenFL in removeChild() method

2015-03-08T02:01:49+00:00

I have already made a post on GitHub about this issue here. This post is just to submit some code demonstrating the issue I am experiencing and to see if anyone knows what I am doing wrong, or if this is really a memory leak in Away3D.

DelaunayMesh - BUG

2012-07-13T00:33:25+00:00

I am playing with Delaunay extrusion and it is not drawing my mesh correctly. I tried same coordinates with Linear Extrude and it works fine. Here is example

var vec= new Vector.<Vector3D>;
vec.push(new Vector3D(4,0,-534.6));
vec.push(new Vector3D(1338.4,0,-534.6));
vec.push(new Vector3D(1338.4,0,-4));
vec.push(new Vector3D(914.4,0,-4));
vec.push(new Vector3D(914.4,0,-170.6));
vec.push(new Vector3D(4,0,-170.6));

var plane= new DelaunayMesh(mat, vec, DelaunayMesh.PLANE_XZ, false,false, true ); 

I hope this is easy to resolve.

Screenshot does not work on multiply views

2015-01-28T01:45:07+00:00

Hi,

The problem is shat queueSnapshot does not work on multiply views and the reason is the code in RendererBase.as:

if (!_shareContext) {
                if (_snapshotRequired && _snapshotBitmapData) {
                    _context.drawToBitmapData(_snapshotBitmapData);
                    _snapshotRequired = false;
                }
            } 

Any workaround?
