The main goal of GLKit is to simplify many repetitive and error prone tasks that developers face when building OpenGL code. It supports: texture loading, view and view controller integration of OpenGL content, OpenGLES effects and a OpenGLES 1.1 effect compatibility kit for OpenGLES 2.0 apps.
GLKit offers a convenient way of loading images as GL textures -- both synchronously and asynchrously. The GLKit.GLTextureLoader can load textures and cube maps from MonoTOuch.CoreGraphics.CGImage objects, in-memory binary data, files and arbitrary Foundation.NSUrl locations. The textures are returned as GLKit.GLKTextureInfo objects.
It is now very easy to blend OpenGL content with Views and ViewControllers using GLKit.GLKView and GLKit.GLKViewController.
The GLKit.GLKBaseEffect class contains the most commonly used OpenGLES 1.1 effects for use in 2.0 applications. These include lightning, materials, multi-texturing, fog, constant color and transformations.
Other effects part of GLKit include GLKit.GLKSkyboxEffect and GLKit.GLKReflectionMapEffect.
