Away3D Forum Detect software or hardware mode

Detect software or hardware mode Software: Away3D 4.x

Felix af Ekenstam, Newbie Posted: 16 January 2012 05:25 PM Total Posts: 7 Hi, What is the best way to detect if the user is running in hardware or software mode in Away3d 4? I want to be able to for off all effects to make software mode possible. I tried to check view.stage3DProxy.context3D.driverInfo directly after creating my view but that gives me the classic error: TypeError: Error #1009: Cannot access a property or method of a null object reference. I guess the stage3DProxy is not initiates yet or something. Should i listen for some event before calling this?

Just put a listener on the main stage3D object and request a new context (or wait until Away 3D does) and it will fire an event when the context is created. And that context contains info about render state etc. var hwCheck = stage.stage3Ds[0]; // listen to the context creation event hwCheck.addEventListener(Event.CONTEXT3D_CREATE, check); var isHardware function check(e=null){ hwCheck.removeEventListener(Event.CONTEXT3D_CREATE, check); var context3D:Context3D = hwCheck.context3D; // hardware of software ? var isHardware= context3D.driverInfo.toLowerCase().indexOf("software") == -1; context3D=null } // request the 3d context hwCheck.requestContext3D(Context3DRenderMode.AUTO);

Felix af Ekenstam, Newbie Posted: 17 January 2012 12:17 PM Total Posts: 7 [ # 4 ] Yes I use that one, but it has the same problem. I still don’t know when it is ready to tell me this info. From what I understand i basically returns _views[0].renderer.stage3DProxy.context3D that would be null until the context is created. I need to know before I start creating my scene if it is hardware or software so that I can adjust my setting accordingly. In that case my above code works well. It would be nice if View3D did dispatch an event when the context is created though. Maybe it does?
