Computes and returns emission angle in degrees given the observer position.
Emission Angle: The angle between the surface normal vector at the intersection point and a vector from the intersection point to the spacecraft. The emission angle varies from 0 degrees when the spacecraft is viewing the sub-spacecraft point (nadir viewing) to 90 degrees when the intercept is tangent to the surface of the target body. Thus, higher values of emission angle indicate more oblique viewing of the target.

Computes and returns incidence angle in degrees given the sun position.
Incidence Angle: The incidence angle provides a measure of the lighting condition at the surface intersection point. The angle between the surface normal vector at the intersection point and a vector from the intersection point to the sun. The incidence angle varies from 0 degrees when the intersection point coincides with the sub-solar point to 90 degrees when the intersection point is at the terminator (i.e., in the shadowed or dark portion of the target body). Thus, higher values of incidence angles indicate the existence of a greater number of surface shadows.

Default occulsion implementation.
This method is originally copied from Sensor::SetLocalGround(bool backCheck). This version checks for the emission angle from the observer to be less than or equal to 90 degrees.
It is recommended that models derived from this base class reimplement this method if a more robust, efficent test can be made.
Note this implementation does not handle occlusion!
