Drawing Stage3D to a BitmapData? Software: Away3D 4.x

loungelizard, Newbie Posted: 27 February 2012 11:31 AM Total Posts: 14 Is it possible? Or does Away3D provide a means to reach the Stage3D render buffer to draw it onto a BitmapData? The reason is that I’m writing a screenshot util for AIR and when capturing the stage, any stage3D content is not captured since it’s not on the AS3 display list. Please tell me there is a way to do that because if not that would suck immensely! o_O
loungelizard, Newbie Posted: 27 February 2012 01:17 PM Total Posts: 14 [ # 1 ] Ok, a step further ... I’m trying to use `stage.stage3Ds[i].context3D.drawToBitmapData(image)` But getting a Exception fault: Error: Error #3692: All buffers need to be cleared every frame before drawing. at flash.display3D::Context3D/drawToBitmapData() I guess it’s better not to tamper with the buffer where Away3D should handle this stuff. Question is now whether Away3D has a way to draw the render buffers to bitmap?

Baush, Sr. Member Posted: 19 October 2012 09:47 PM Total Posts: 135 [ # 7 ] As this seems to be an often requested question, perhaps it would be useful to add a getBitmapData() method to the renderer class..
Mr Margaret Scratcher, Sr. Member Posted: 19 February 2014 11:17 PM Total Posts: 344 [ # 8 ] In case anyone else is looking for this - it has now changed, actually a little more simple… `var stageBMD:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight); var stageBitmap:Bitmap = new Bitmap(stageBMD); view.renderer.queueSnapshot(stageBMD);`
Mr Margaret Scratcher, Sr. Member Posted: 25 February 2014 12:12 AM Total Posts: 344 [ # 9 ] Hmm, might have spoken too soon - I’m having difficulties posting this data onto anything else… Weird bitmap data problem…
Francesco, Newbie Posted: 24 January 2015 08:54 PM Total Posts: 4 [ # 10 ] John Brookes - 01 March 2012 05:34 AM _view.renderer.swapBackBuffer = false; _view.render(); _view.stage3DProxy.context3D.drawToBitmapData(bitmapHolder.bitmapData); _view.renderer.swapBackBuffer = true; I have this problem using your code: 1119: Access of possibly undefined property swapBackBuffer through a reference with static type away3d.core.render:RendererBase. Any suggestion
rdoi, Member Posted: 26 January 2015 05:38 PM Total Posts: 86 [ # 11 ] I think the method posted by Brookes (RIP) was deprecated. In Away 4.1x, try using the one proposed by “@Mr Margaret Scratcher” 2 replies above yours.
