Moving along a object.

[soshiant]

Hi!
Looking around to see if anyone has a clue on how to do the following:
I want my objects to be able to move along a surface.
Much like what happens using normal align but i dont want to align. I want
to be able to translate/move the object along the surface.
I'm going to use arbitary surfaces.

/Martinwhat kind of surfaces?

NURBS and Patches is easy. (surface ctrls )

Polygons impossible.( because every 3 points in space create a surface so the forth point might not be at the same surface, got it?)

Meshes, must do alot of computation.( you can find the Alg if you realy need it. ):)
