Vuforia SDK Version: ios 7.0.43 -
Description with steps to reproduce: In the sample code function
[code]
- (CGRect)getCurrentARViewFrame
{
CGRect screenBounds = [[UIScreen mainScreen] bounds];
CGRect viewFrame = screenBounds;
// If this device has a retina display, scale the view bounds
// for the AR (OpenGL) view
if (YES == vapp.isRetinaDisplay) {
viewFrame.size.width *= [UIScreen mainScreen].nativeScale;
viewFrame.size.height *= [UIScreen mainScreen].nativeScale;
}
return viewFrame;
}
[/code]
The lines
[code]
if (YES == vapp.isRetinaDisplay) {
viewFrame.size.width *= [UIScreen mainScreen].nativeScale;
viewFrame.size.height *= [UIScreen mainScreen].nativeScale;
}
[/code]
seem to be unnecessary. In the case of a retina display, iOS already doubles the backing store, so there's no need to double the size of the frame. I removed these lines and all the samples I tried still worked fine. -
