Class PAPathParametric

java.lang.Object
net.paulhertz.pixelaudio.curves.PAPathParametric
public final class PAPathParametric extends Object
PAPathParametric Parametric view of a polyline path (e.g., polygonized Bezier). u ∈ [0,1] → (x(u), y(u)) For now, u is interpreted over the *index* of the point list: - u = 0 → first point - u = 1 → last point - intermediate u → linear interpolation between neighboring points This preserves any "bunching" of points in high-curvature regions produced by the polygonization.
