CYLINMAP

THE BOX'S MAIN HELP:
This function returns UU and VV, the coordinates for cylindrical mapping.
The central axis is along Z.
The point on the equator where (UU,VV) equals (0,0) 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 origin of the cylindrical projection.
This must be a point. The default is point(0,0,0).

X (input):
This point represents the Xaxis for the cylindrical projection.
This must be a point. The default is point(1,0,0).

Y (input):
This point represents the Yaxis for the cylindrical projection.
This must be a point. The default is point(0,1,0).

Z (input):
This point represents the Zaxis for the cylindrical projection.
This must be a point. The default is point(0,0,1).

UU (output):
This float is the "latitudinal" or "horizontal" mapping coordinate.
The central axis is along Z.
The point on the equator where (UU,VV) equals (0,0) is at X.

VV (output):
This float is the "vertical" mapping coordinate.
The central axis is along Z.
The point on the equator where (UU,VV) equals (0,0) is at X.
