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?
I've got into the problem since, so the posts about the steps of the solution can be followed here:
