sample apps run, but no AR happens

I installed the QCAR SDK and compiled 2 different sample apps (Dominoes and Image Target). They built successfully in XCode and ran on my iPad2. The camera turned on, but nothing ever appeared. In Dominoes, it displayed the Clear and Run buttons, but I could not get it to display any dominoes no matter how many times I tried to draw a line on the screen. Then with Image Target, I printed out the stones image and pointed the camera at it, but it never displayed the teapot. Any suggestions? I'm developing on a Mac Mini running 10.6.8, and XCode 4.0.2.

Hi proteus7, 1) are you using the release version (reports "INFO: QCAR SDK version 1.0.0" in the log)? 2) make sure the target is fully visible in the camera - try from above, and hold the camera steady. 3) It can help to switch the Scheme to be using a Release build. Let us know if you are still

Actually, no, I didn't realize (or 'realise') that Dominoes needs the stones target. That was it! It works now! Image Target did not work, but that's OK, I just wanted to make sure that it could be done before I spent any time learning it. Good job moderating, Moderator!
