Track on surface to get closer to point.

Possible situations:

1. reached endpoint
2. reached edge (normal situation)
3. reached end of surface (edge on single face) Input:
starting position+triangle/edge/point (so has to be on surface!)
(optional) previous position+triangle/edge/point to prevent going back. Set index (of triangle/edge/point) to -1 if not used.
end position+triangle/edge/point (so has to be on surface!)
plane to follow. Has to go through end point! Returns:
true if end point reached (situation 1)
new position+triangle/edge/point Caller has to check for situation 3 by checking that triangle() is not set.
