Question

Bezier Curves. Write the properties of the Bezier curves, prove all properties. Discuss the Parametric Continuities and Geometric Continuities of Bezier Curves, with suitable expressions, equations and examples. Explain the purpose of control points in Bezier, a Cubic Bezier curve has control points P0 (0, 0); P1 (5, 40); P2 (40, 5); P3 (50, 15). Determine 2 more points on the same Bezier curve. Draw a rough sketch of the curve and show coordinates of various points on it?

Bezier Curves: Properties and Continuities

Properties of Bezier Curves:
1. Degree: The degree of a Bezier curve is one less than the number of control points.
2. Convex Hull: The curve is always contained within the convex hull of its control points.
3. Endpoint Interpolation: The curve starts at the first control point and ends at the last control point.
4. Affine Invariance: Bezier curves are invariant under affine transformations.
5. Local Control: Each segment of the curve is influenced only by a subset of the control points.
6. Smoothness: Bezier curves generally produce smooth curves with a single parametric _________ ___ ______ __________ __________ _____ _________ _______ ___.
