Drawing Tablet Library For Processing

marcus • March 18th, 2008

libTablet aims at becoming a (cross-platform) Java drawing tablet library that plays nice with Processing. It gives you easy access to your tablets pressure, tilt and rotational data in your sketches/ Java applications.

Since my most immediate requirement currently is to have it working on Mac OS X, it is yet not really cross-platform. However the plan is to wrap JTablet on Windows to provide a common interface for easier development/ deployment across these systems.

Releases

version 0.1

first draft, mac os x only
» Tablet-0.1.zip

Source

You can get the latest version via mercurial with:

hg clone http://hg.infostuka.org/hg/libTablet/

Useage

Simply create a PTablet object before you initialize your sketch, which you can then use to query your tablet for: pressure, tiltX, tiltY, rotation etc.

import processing.opengl.*;
import infostuka.lib.tablet.p5.*;

PTablet tablet;

void setup ()
{
    // ATTENTION - new PTablet() HAS to be created before calling size()
    tablet = new PTablet(this);
    size(800, 600, OPENGL);
}

void draw ()
{
    if (mousePressed) {
        float brushSize = tablet.pressure * 100f;
    System.out.println("TILT " + tablet.tiltX + " " + tablet.tiltY + " ROT " + tablet.rotation + " THETA " + theta);
    ...
    your drawing commands here
    ...
    }
}
