Constructor Detail

ZoomPan

public ZoomPan()

Initializes the fields to: Velocity = 0.9f Roh = 1.4142f w0 = 50 w1 = 50 u0 = 0 s = 0 End = new Vector2f(1,1) Start = new Vector2f(0,0) And calculates additional Curve dependent fields

Method Detail

advance

void advance(float t)

Advances the curve by the timestep t

Parameters:

t - Timestep to calculate

calcParams

void calcParams()

This function precalculates the parameters that define the curve. See Paper for additional information.
