The 3D graphics world is definitely taking notice, since a lot of high-end software, including games, requires a three-button mouse or double thumbsticks to navigate their worlds. So far it’s not terribly interesting, which is why you’ll be adding the wow factor by implementing gesture recognizers! Gesture RecognizersĪny new iPhone/iPad user will have marveled at the smooth gestures that allow you to navigate the OS and its apps, such as pinching to zoom or swiping to scroll. The current model viewer is very simple, allowing you to view two different models in a fixed position. Have a look at MainViewController.m to see how everything works, and then build and run. However, the project has been refactored to present a neat and tidy GLKit View Controller class- MainViewController-that hides most of the OpenGL ES shader implementation and 3D model rendering. The iPhone/iPad Simulator can’t simulate all the gestures covered here.įirst, download the starter pack for this tutorial.Īs mentioned before, this is essentially the same project featured in our Blender to OpenGL ES tutorial series. Note: Since this is literally a “hands-on” tutorial that depends on gestures, you’ll definitely need an iOS device to fully appreciate the implementation.
