   Does anyone here have experience getting Qualcomm's QCAR SDK working with Cocos3D?
   I'm working on this now, and have made a great deal of progress; but would love some tips.

   Brief background:
   The QCAR SDK consists of a library, and a bunch of exposed classes.
   It boils down to a state machine which is woven across the classes. They poke the state machine from various points in their ViewController and View; and their state machine calls a bunch of delegates they've also included in the Views. You can subclass their views to make the magic happen.

   Their SDK is pretty nice; you give it some target images; and they let you know when they've spotted one of them and where it is in 3D space.

   I want to draw some complicated 3D scenes, and would therefore like to use Cocos3D! The artist gave me a POD file, which is displaying quite nicely.

   My problem in a nutshell is that I'm not seeing the video from the QCAR library. The QCAR lib controls the camera and calls my "renderFrameQCAR" delegate method many times/second. I'm expected to do my openGL drawing within that method. Within that method, I can make a call back into their library, and if the openGL state is setup to their liking; they draw the camera input as a texture.

   I know the camera is running because I see from DBG output that my image is recognized when I point at it.

   I'm using QCAR v1.5. Any tips would be greatly appreciated!

   Read this post https://ar.qualcomm.at/arforums/showthread.php?t=980&highlight=models they talk about the methods of running video background. Can you post some code about your work integrating cocos3d and qcar. Thanx.

   The CCDirector class cluster controls updating and rendering. Have a look at the CCDirectorIOS drawScene method. You may be able to delegate to that method from your QCAR renderFrameQCAR method.

   But caveat emptor. I've never tried such a feat.

   I have the following problem. I created a cocos3d app and add de qcar api into it. I can run Multlitarget sample if I use a custom EAGLView (say AREAGLView) that not subclass cocos EAGLView. But if I subclass my AREAGLView from cocos EAGLView i can't see the qcar camera background, but I can track successfully the trackable object. Any advice? Thanks in advance.

   You can try to use CC3EAGLView with a CCNodeController that has the isOverlayingDeviceCamera property set to YES.

   To see this in action in the CC3DemoMashUp demo app, in the CC3DemoMashUpAppDelegate applicationDidFinishLaunching: method, add the following line after the lines that create the viewController:

   viewController.isOverlayingDeviceCamera = YES;

   Were you able to properly connect it? Im trying to do the same but I don't really know where to start. How should I properly rename the EAGLview classes (in which files). I read the thread in that link that mkotliarov posted but I'm still confused. And also, is it better to add Cocos3d files to qcar template, or the other way around.

   Any help is much appreciated and thank you in advance.
