Yes, I was trying to figure out a robust as well as efficient method to do that numerically, as you are right the analytical solution doesn't exist and the problem is : the only numerical way known...

I wouldn't have come to this forum if it was that simple. I could figure out that much myself. The problem is: to find the minimum t, I have to equate the derivate of this distance to zero, which...

How to find closest distance of a point P(Px, Py) from a bezier curve given by four control points A, B, C and D?

I was studying Frenet trihedron (or frenet frames/frenet vectors) for a project and came need to somehow use the term torsion = - N x B'

where N is the unit normal vector and B' is the...
