Ok, some math following:
we'll start with a simplified case, mapping a line to a circle in 2D space.
suppose we have a line given by a point o_ and a directlional vector y_
which we conveniently normailse to have a length of 1: |y_|=1. The equation
for the line is then
x1_ = o_ + a * y_. (1)

It's done like this. Take a mathematical representation of the sphere with 2
parameters. Use for example polar coordinat
I have a local coordinate system that lies in just the XY plane. I want
that coordinate system mapped onto the surface of a sphere... I want to be
able to pick any point on the surface of the sphere, then translate the
origin of my local coordinate system to that location (the plane would be a
