Minimum distance in space
Sorry if this is really basic (it certainly does sound really basic to me), but I'm quite bad at maths: Given a plan with equation Ax + By + Cz + D = 0 and a point (x0, y0, z0), how do I find the minimum distance between both?

dx = Ax-x0
dy = By-y0
dz = Cz-z0

distance = sqrt(dx*dx+dy*dy+dz*dz)

I think that is what you are saying.
