Hello list,
I had a doubt, will try to explain.
I wanted to define a line in a 3d space through 2 points, and be able to
find out the distance from another point to that line. Since I'm very
bad at math, I wanted to know if anyone has done something similar, or
knows how to get to it.

first example on the page, you just need to clamp u to [0..1] if you
want to make it work for a line segment instead of an infinite line.
it looks interesting, and I also checked for more content with a similar title.
the thing is, my math/geometry skills are too bad, and I don't understand where
they get the formulas for the points and lines. I'll keep watching the links,
but I might not get it in time for the purpose I was looking for.
thanks anyway,
João
