I've seen the comp.graphics.algorithm FAQs on how to get the shortest

distance from a point to a line, but that method applies to 2d space. Could

anyone assist me in obtaining an algorithm that works in 3d space?

Thank you,

1. Q: Point on line segment closest to a 2D/3D point

just wondering if anyone had any quick way of finding out a point on a

line segment that lies closest to a separate point in 3d space (and also

a method for 2d space)? i'm having to do it with integers, and it's part

of an inner loop, so i don't want to mess around with normalising vectors

etc if possible. i realise that it would be possible to find the closest

point on the infinite line on which the line segment lies, and then test

whether it sits inside the line segment, but that's probably a bit too

expensive.
