in my Priithon project I the got from this

Hi,
A background in linear algebra helps. I just came up with this method
(which, because I thought of it 5 seconds ago, I don't know if it works):
Line p1, p2
Point v
costheta = normalize(p2-p1) dot normalize(v-p1)
dist = length(v-p1)*sin(acos(costheta)

Here's a good list of basic geometry algorithms:

supose you have a line defined by two points and a point. you want the distance
what are easiest possibilities? i am doing it, but its nasty'n ugly
