It works. But it...

Hi, I'm playing with OpenGL ES on iPhone and I'm trying to rotate a model by panning with the finger. I discovered the open source app Molecules that let's you do that and I'm looking at that code, but when it comes to rotate a model of mine I'm able to rotate it only around a point distant in the space (like it was in orbit as a satelli...

Don't Allow / Allow" If the user tapped "Allow," it would auto-fill their email address (the one they have configured in Ma...
