   Surface plane normal vectors

Question 

Given the X Angle and Y Angle from the Surface Plane tool, how do I find the surface normal vector?

Answer 

Sensor Model G2xxx, G3xxx
Firmware Version All
SDK Version n/a

The surface normal of a plane measured with the Surface Plane tool has the following vector:

nx -sin(Y_angle)
ny -sin(X_angle) * cos(Y_angle)
nz cos(X_angle) * cos(Y_angle)
