Hi all, im in need of an equation that works out the distance between two points in 3d space, using x1,y1,z1 & x2,y2,z2 as coordinates. I had a go but its been so long ive totally forgotten it. Any help is appreciated.

Cheers

IIRC...

deltaX# = x1 - x2
deltaY# = y1 - y2
deltaZ# = z1 - z2

distance# = sqr((deltaX#*deltaX#)+(deltaY#*deltaY#)+(deltaZ#*deltaZ#))

I've seen this question come up before and people posting more elegant solutions, so this topic is worth searching the forums for.
