Intermediate Topic 27 of 49 Graphics, Vision & Media

Bézier Curves and Splines

Smooth curves defined by control points.

How it works

A cubic Bézier is defined by 4 control points via Bernstein polynomials or de Casteljau's algorithm; splines join curves smoothly (B-splines, Catmull-Rom).

Where it is used

Fonts, vector paths, animation curves.

Common pitfall

Continuity (C0, C1, C2) at joins matters for smoothness.

Where it fits in the course

Bézier Curves and Splines is topic 27 of 49 in Graphics, Vision & Media, rated Intermediate. It follows Global Illumination. The next topic is Mesh Simplification.
