sample is. Uses either face normal, edge normal or point normal (non-trivial). Uses triangle::classify.

static

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.

void track	(	const triSurface &	s,

static

Track from edge to edge across surface. Uses trackToEdge.

Not really useful by itself, more example of how to use trackToEdge. endInfo should be location on surface. hitInfo should be initialised to starting location (on surface as well). Upon return is set to end location.
