Use of control points and ways of specifying spline curve

Question

Illustrate use of control points and ways of specifying spline curve?

Answer 1

Spline curve can be precise by providing a set of coordinate positions known as control points, which indicates general shape of curve, which can specify spline curve.

The ranges of ways of specifying spline curve are:-

• Using a set of boundary conditions that are imposed on the spline.

• Using the state matrix that characteristics the spline.

• Using a set of blending functions that calculate the positions along the curve path by specifying combination of geometric constraints on the curve.
