   I debugged the issue.

   1. Not sure this is a problem, but in SimpleVisualizationController.mm, I was getting cautions so renamed this method:
      - (void)buildProjectionMatrix:(Matrix33)cameraMatrix screenWidth:(int)screen_width screenHeight:(int)screen_height projectionMatrix:(Matrix44&) projectionMatrix

   2. In ViewController.mm, frameSize is not correctly being evaluated and returns (0,0):

   self.visualizationController = [[SimpleVisualizationController alloc] initWithGLView:self.glview
                                                                                calibration:camCalib
                                                                                  frameSize:frameSize];
   

   To fix this fast: Just change frameSize parameter to CGSizeMake(640,480) (which is the correct video dimensions as the entire project revolves around that resolution preset in VideoSource).

   To fix this correctly: Implement a notification to get the correct frameSize when the camera is ready. The problem is in VideoSource.mm getFrameSize returning 0,0 because its not ready. Here is a link to implementing that notification: http://stackoverflow.com/questions/26175409/cmformatdescriptionref-and-cmvideoformatdescriptiongetdimensions
