public class Visualizer
extends com.cycling74.max.MaxObject

This class encapsulates a graphical animation that provides a visualization of a single particle moving around a space. The visualization relies on the client to dictate the position of the particle. The animation is driven by the client successively updating the particle's position.

Constructor Detail

Visualizer

public Visualizer(int horizontalDimension,
                  int verticalDimension)

Method Detail

inlet

public void inlet(java.awt.Point p)

Specify the next position of the particle and redraw the canvas.

Parameters:

p - the next position of the particle.

setColor

public void setColor(java.awt.Color c)

chooseColorFromSpectrum

public static java.awt.Color chooseColorFromSpectrum(float normalizedHueAngle)

Returns a color from the spectrum that spans from red to violet. A value of 0 returns red. The intermediate values span red, orange, yellow, green, blue, indigo. A value of 1 returns reddish-indigo (but mostly reddish). Hue angle in the HSV color model ranges over [0,2*Math.PI] in radians or [0,360] in degrees. See the HSV model illustration in wikipedia entry [http://en.wikipedia.org/wiki/HSL_and_HSV]. This method accepts a value over the interval [0,1].

Parameters:

normalizedHueAngle - a float on the closed interval [0,1]

Returns:

a color, as described above
