Class DancerBezierPath

java.lang.Object
  net.cscott.sdr.calls.DancerBezierPath

All Implemented Interfaces:

Comparable<DancerBezierPath>

public class DancerBezierPath
extends Object
implements Comparable<DancerBezierPath>

Low-level version of DancerPath which explicitly represents the Bezier paths for the dancer to follow. This is more useful than the usual DancerPath, which is Position-based, when doing low-level affine path transformations like hexagon/octagon and size expansion, since it separates the direction from the location. DancerBezierPath compares to others based on start time, to make it easy to keep a list sorted by start time.
