Spline curve can be either
WebThe curve is parametrisized along its length. So the curves are not separate they do not interpolate form 0 to 1 on each span like Beziers do. Instead the underlying curve has a cusomizable parameter range. The parameter is stored in something called a knot, and each knot can have a arbitrary increasing value in the sequence. Web9 Dec 2014 · A spline has variable curvature that changes as the user wants it to change, and can flip convexity from one side to the other. You can assign tangency at the end of a …
