Away3D Forum Render Bitmap with multiple views

Render Bitmap with multiple views Software: Away3D 4.x

Beek, Member Posted: 03 March 2015 11:56 PM Total Posts: 67 Hi, I’m attempting to render a bitmap using Stage3dProxy with multiple views. `view.renderer.queueSnapshot(bm)` Works fine without a stage3Dproxy, however with a proxy it doesn’t render anything until the proxy is removed, and the normal rendering loop is called. I’ve seen this https://github.com/away3d/away3d-core-fp11/issues/714 Which appears to be a new bug, and I’ve tried to fix it by implementing the queueSnapshot procedure in Stage3DProxy.as, as described, by adding `if (_snapshotRequired && _snapshotBitmapData) { _context3D.drawToBitmapData(_snapshotBitmapData); _snapshotRequired = false; }` into the onEnterFrame loop, however it’s just rendering an empty bitmap. Has anyone any idea how to render a bitmap with stage3dproxy?
Beek, Member Posted: 04 March 2015 04:23 AM Total Posts: 67 [ # 1 ] I’m close with 2 attempts: This is 2 views for side by side VR. 1. Remove SharedContext, render and put it back `view.shareContext = false; view.render(); transitionBitmap.bitmapData = bitmapData; transitionBitmap.bitmapData.merge(bitmapData, new Rectangle(0,0,width/2, height),new Point(width/2,0),256, 256, 256, 256); stage3DProxy.clear(); view.shareContext = true;` This generates the image, but when the loading is done and the image is taken away, the right hand view is white, and it won’t come back unless I reinitialize the side by side view, which is expensive. 2. using the fix suggested on github, by editing Stage3dProxy var bm:BitmapData = new BitmapData(width/2, height, false,0xffff90); view.render(); view.stage3DProxy.addEventListener("snapshotReady", function(){ transitionBitmap.bitmapData = bm; transitionBitmap.bitmapData.merge(bitmapData, new Rectangle(0,0,width/2, height),new Point(width/2,0),256, 256, 256, 256); transitionBitmap.blurSlowly(0.2); }); view.stage3DProxy.queueSnapshot(bm); view.render(); And adding the function to the render loop `if (_snapshotRequired && _snapshotBitmapData) { _context3D.drawToBitmapData(_snapshotBitmapData); _snapshotRequired = false; dispatchEvent(new Event("snapshotReady")); }` This seems to work, however the captured bitmap is black, but it doesn’t destroy the side by side view. Anyone any ideas!?

I’m not an expert but the order of your clear(), render() and present() calls looked flawed. it should be something like that: `//Prepare Stage3D for render operations stage3DProxy.clear(); //Render all views view.render(); iinterfaceView.render(); //Present everything stage3DProxy.present();`
