Knot Definition and what do they actually do
I have been looking at spline's and limier interpolation. Thus far I have figured that a simple mesh can be used as a set of control points. And that another object can be created from the control points by interpolating the control points and then creating a new object from the interpolation. But I have not yet understood what the knots are and what they are supposed to do. So, what are knots and what do they do ? Rob . . .
