Simulate a panorama. Only works with mc_sensorposition and mc_backward. With mc_backward, the user decides what area of the full 4$ \pi$ globe is simulated. The first dimension gives $ \theta$ and goes linearly from 0 (zenith) to 180 (nadir), while the second dimension gives $ \phi$ and goes from 0+$ \epsilon$ to 360-$ \epsilon$ . 0 means north/south/east/west here.
