This is great!! I’ve been looking for a lightweight format to bring models+animation in from Maya and I was going to use the PowerVR POD format, but this is great because md2 can also be used on other devices (on android, for example) that don’t use the PowerVR chipset. Thanks!!

I’m glad you found it useful. It’s also worth noting that the original Quake 2 implementation faked lighting of MD2 models via vertex color however I simply used GL lighting in the iPhone project. The article linked at the bottom of the post show’s the fake lighting implementation if you’re interested.

Thank you for posting this code because it aided me in getting depth to work on my own application.
I was actually doing things right but after implementing your camera code, I realised I was simple not putting the square somewhere where I could see it.
Now I’m going past squares and into proper rendering.
