Is there any ready made class/formula somewhere I can use it for control my viewpoint by accelerometer's/compass's XYZ?

I want to achieve the same view control like acrossair uses.

I have the parts (OpenGL space, filtered accel-, compass values, and a cubic panoramic view mapped to a cube around my origin).

Can somebody suggest me where to start at least?
