These c2 interpolating splines yield only "global control" moving any one joint (or control point) changes the entire curve! global control is problematic: • makes splines difficult to design • makes incremental display inefficient there's a fix, but nothing comes for free. two choices: • b splines • keep c2 continuity • give up. Continuity. • parametric continuity coordinate functions. (c) of spline is continuity of. f1’(1) = f2’(0) geometric continuity (g) is continuity of the curve itself. f1’(1) = k f2’(0) for some k. derivatives have same direction, but may have diff magnitude. generally g is less restrictive than c.
