This is a simple app that demonstrates rendering a 3D scene on an iOS device so that it can be viewed on a stereoscopic viewer such as Google Cardboard.
It has very basic head tracking - no forward/backward movement yet but full 360 degree rotation for GLKit and SceneKit demo scenes.
GLKit demo is pretty basic - just a grid of cubes at the moment
SceneKit demo shows a cube of sheres all moving at different speeds
Both sampples render the scene twice and demonstrate rendering to texture techniques.
Also, have stereo image (side-by-side) support now. Supports both parallel viewing (cardboard) and cross-eye (manual) viewing. And allows you to capture your own 3D pictures).
To capture a 3D picture, first show the Stereo Image Viewer
- Click the Capture button. This will show the camera preview image in the left hand window.
- Click the Capture button again to take the left hand picture and it then shows the preview image in the right hand window
- Then, carefully, move your iPhone slightly to the right (approx 2-3cm) just enough to offset the image.
- Press the Capture button again to capture the right hand picture.

The SceneKit demo (currently looks a little complex but looks great when viewed with Cardboard!
The GLKit demo
BSD-style, with the full license available in LICENCE.
Download the project and run through Xcode on a device. It will run on the Simulator but the performance will be less than optimal, plus head-tracking will not work.
A big thanks for the following:
The perspective projection shader and texture rendering code was based on Brad Lawson's OculusRiftSceneKit demo (https://github.com/BradLarson/OculusRiftSceneKit)
The GLProgram wrapper was taken from Jeff LaMarche's Simple OpenGLES 2.0 Example (https://github.com/jlamarche/iOS-OpenGLES-Stuff)
