Remarks

The RollAngle represents the angle, in degrees, of the camera about the line of sight between the observer and target. Angles will be reported in the range >=0 and <360. Angles can be given outside of this range but will be 'wrapped' to the equivalent value in the 0 to 360 range. For example -1 is the equivalent of 359 and 361 is the equivalent of 1.

A RollAngle of 0.0, the default, is straight up relative to the Z axis in the scene. Increasing the RollAngle will tilt the camera clockwise about the line of sight.
