Use of control points and ways of specifying spline curve
Illustrate use of control points and ways of specifying spline curve?
Expert
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.
