c++ - What exactly are knots (b-spline) -


knots things make curve continuous, in bezier curves, line segment mid point control point have have same tangent , length , if bezier curves c-continuous.

so, knots have read parameters of spline handle start , end points hence c-continuosity of curve.

so, knot data type ?

any idea's?

a b-spline piecewise polynomial, , knots points pieces meet. knot have same type argument polynomials. supply value @ each knot, , either control point between each consecutive pair or first derivative. say, smoothness depends on function , derivatives being continuous @ knots.
