Beginning OpenGL

It has been a long time since my last update, but I have finally found the time to start learning OpenGL. There seems to be very few online tutorials directed at Objective-C specifically, so I have had to cobble together information from many different sources. However, I have now managed to create a very simple application that draws an OpenGL scene and updates it 60 times a second. Behold the rotating triangle:

Using this framework, I can now use general OpenGL tutorials. Soon, I hope to post experiments with more complicated meshes.
