spherical2cartesian
Converts a set of spherical coordinates into cartesian.
Inlets
frac32 radius
frac32 inclination: angle with the z axis (0 = 0 degrees; 64 = 180 degrees)
frac32 azimuth: angle with the x axis on the xy projection (0 = 0 degrees; 64 = 360 degrees)
Outlets
frac32 x coordinate
frac32 y coordinate
frac32 z coordinate
