Sample app from the OpenGL ES for iOS 5 talk by Chris Miles at Swipe Conference 2012.

http://swipeconference.com.au/sessions#12-opengl-es-with-ios-5-part-1-learning-to-draw

The app demonstrates how to implement simple OpenGL ES rendering concepts using GLKit, such as:

  • Setup OpenGL ES scene using GLKViewController + GLKView
  • Rendering triangles (GL_TRIANGLES) and meshes made of triangles
  • Applying vertex colours, using GLKBaseEffect
  • Applying lighting, using GLKBaseEffect
  • Applying texturing, using GLKBaseEffect and GLKTextureLoader
  • Using Vertex Array Objects (VAO) and Vertex Buffer Objects (VBO)
  • Using interleaved vertex arrays (IVA)
  • Animating vertex positions (tap screen to animate between flat triangles and 3D open box shape)

The sample app is universal and supports all orientations.
