Leap Motion library for Processing including gesture support

LeapMotionP5

A Leap Motion Library for Processing

Working with all Processing versions and all operating systems (OSX, Windows), with the newest version of the leap motion sdk. Moreover it is including a variety of gestures. Just download the library archive at the bottom of this readme and extract it into the libraries folder of your processing sketchbook and your're ready to go.

Check http://www.onformative.com/lab/leapmotionp5 for additional information about the library.

Download

Download from here https://github.com/mrzl/LeapMotionP5/archive/master.zip extract the folder in the archive into your processing libraries folder and rename it from LeapMotionP5-master to LeapMotionP5. After that restart Processing and the library should be included. Check the examples within the library.

Examples

Basic Example

import com.onformative.leap.LeapMotionP5;
import com.leapmotion.leap.Finger;

LeapMotionP5 leap;

public void setup() {
  size(500, 500);
  leap = new LeapMotionP5(this);
}

public void draw() {
  background(0);
  fill(255);
  for (Finger finger : leap.getFingerList()) {
    PVector fingerPos = leap.getTip(finger);
    ellipse(fingerPos.x, fingerPos.y, 10, 10);
  }
}

public void stop() {
  leap.stop();
}
