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

Is this possible?

I understand this reasoning for javax.media.j3d.* classes, but I'm more
concerned with not having getters and setters for the guys like
] why aren't javax.vecmath.* classes Java beans?
Probably because of safty. They have to be immutable to garantee safe
execution. The same as strings.

Yeah I'm not getting it. How many Quaternions will you have? Do you
build one for each axis (x,y,z)? Once you have them, how d

Think the earth. I've got two points on the Earth, the upper left and lower
right of a rectangle (think square, not box). Now those two points lie on a
plane. I know which plane because a vector from the center of the earth
