SPHEREMAP

THE BOX'S MAIN HELP:

This function returns UU and VV, the coordinates for spherical mapping.
The north pole is on Zaxis.
The point on the equator where UU equals 0 is mapped is at the X axis.

PP (input):

This is the point on surface to be projected. The default is P.

O (input):

This point represents the center of the spherical projection.
This must be a point. The default is point(0,0,0).

X (input):

This point represents the Xaxis of the spherical projection.
This must be a point. The default is point(1,0,0).

Y (input):

This point represents the Yaxis of the spherical projection.
This must be a point. The default is point(0,1,0).

Z (input):

This point represents the Zaxis of the spherical projection.
The north pole is on Zaxis.
This must be a point. The default is point(0,0,1).

UU (output):

This float is the "latitudinal" or "horizontal" mapping coordinate.
The north pole is on Zaxis.
The point on the equator where UU equals 0 is mapped is at the X axis.

VV (output):

This float is the "longitudinal" or "vertical" mapping coordinate.
The north pole is on Zaxis.
The point on the equator where UU equals 0 is mapped is at the X axis.
