Method Detail

cubicInterp

public static float cubicInterp(float p0,
                                float p1,
                                float p2,
                                float p3,
                                float t)

Evaluate a cubic bezier with the given four control points. The time argument should be between 0 and 1, inclusive.

cubicDeriv

public static float cubicDeriv(float p0,
                               float p1,
                               float p2,
                               float p3,
                               float t)

Evaluate the derivative of a cubic bezier with the given four control points.

quadInterp

public static float quadInterp(float p0,
                               float p1,
                               float p2,
                               float t)

Evaluate a quadratic bezier with the given three control points. The time argument should be between 0 and 1, inclusive.
