Basic heli 6DOF movement using the Metal API.
Boilerplate Xcode Metal project showing how to do basic heli 6DOF movement without gimbal lock. Also, the infamous XFile.cpp makes it to the net. This is not (the beginning of) a port of R/C Sim Sikorsky to Metal.
Explaining gimbal lock.

This project started as a port of https://github.com/haroldserrano/renderingTextUsingOpenGLiniOS to Metal but turned into something completely different. Only the font atlas remains...
The complete tutorial on how to render Text using OpenGL can be found here: http://www.haroldserrano.com/blog/rendering-text-using-opengl-es
