Manipulating Objects In 3D Space Using Touch With GLKit And OpenGL ES

I’ve previously mentioned some excellent tutorials on getting started with OpenGL ES 2.0, and maintain a list of GLKit tutorials and examples.

The idea of touching an object displayed on the screen in 3D seems simple enough – but unless you’re a graphics programmer requires you to think in a completely different manner.

Ray Wenderlich has created a guide – going through two different methods on how to rotate an object displayed in 3D using touch in OpenGL ES.

You can find the tutorial on Ray’s site here.

Example project included – so even if you can’t absorb everything you’ll have something you can use.
