WebComputer Graphics WS07/08 – Splines More on Continuity • at one point: • Geometric Continuity: – G0: curves are joined – G1: first derivatives are proportional at joint point, same direction but not necessarily same length – G2: first and second derivatives are proportional • Parametric Continuity: – C0: curves are joined WebGeometric continuity is a bit less restrictive, it means that the derivatives must have the same direction, but may have a different magnitude. Next we will see how to achieve a better continuity (or smoothness) for our splines. ... A very important curve in computer graphics is a Bezier curve.
