Class BezierInterpolation

java.lang.Object
toxi.math.BezierInterpolation
All Implemented Interfaces:
InterpolateStrategy
public class BezierInterpolation extends Object implements InterpolateStrategy
Bezier curve interpolation with configurable coefficients. The curve parameters need to be normalized offsets relative to the start and end values passed to the interpolate(float, float, float) method, but can exceed the normal 0 .. 1.0 interval. Use symmetrical offsets to create a symmetrical curve, e.g. this will create a curve with 2 dips reaching the minimum and maximum values at 25% and 75% of the interval...

BezierInterpolation b=new BezierInterpolation(3,-3);

The curve will be a straight line with this configuration:

BezierInterpolation b=new BezierInterpolation(1f/3,-1f/3);
