Just started to realize an augmented reality based project, got GPS location, heading, and the two missing variable to manipulate virtual camera is Pitch/Roll.
I'm wondering if there is a ready-made formula I can merge into the project. Could spare me a lot of time. Thanks in advance.
I've got into the problem since, so a realy detailed post about the solution can be read here:
