An Introduction to SceneKit
SceneKit provides some functionality for creating scenes from scratch right in your code, but is primarily designed for working with 3D scene data exported from an external application like Maya, 3DS Max, Modo, LightWave, or Blender. SceneKit uses the Collada file format, which is supported by most (if not all) major 3D programs (though with some caveats I’ll discuss later). The Collada file format doesn’t support just 3D objects, it can store information about an entire 3D scene including lights and cameras as well as armatures and animation data for both simple object animation and complex skeletal animation.
