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

svn co http://svn.infostuka.org/rep/libTablet/trunk/

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.

    if (mousePressed) {
        float brushSize = tablet.pressure * 100f;
    System.out.println("TILT " + tablet.tiltX + " " + tablet.tiltY + " ROT " + tablet.rotation + " THETA " + theta);

libCollada 0.2 released

marcus • September 22nd, 2007

libCollada now does colors!

the library is getting nearer to being actually useful. it now creates new collada materials and effects for you as needed without writing a line of extra code.

libCollada 0.1 released

marcus • September 14th, 2007

finally i found some time to finish a first release of my collada library for processing today.

it’s still quite basic and only exports triangles without any material information. however there have been major refactorings under the hood that will allow to add new features much easier.

it might output garbage when you try to do something clever but give it a go
- your comments & critics are appreciated!

Collada Export Plugin for Processing

marcus • August 8th, 2007

libCollada allows you to easily export 3D geometry and material data in the COLLADA 1.4.1 format from your processing applications. Although processing’s drawing methods and COLLADA’s scenegraph based, more complex 3D description format, do not match directly – the library attempts to do a reasonable conversion, requiring no extra API to learn.

Releases

version 0.2

now creates materials & effects generated from standard p5 drawing commands
» collada-0.2.zip

version 0.1

first public release with examples and packaged for p5
» collada-0.1.zip

version 0.01 (08/06/07)

a first rather rough version that can export basic geometry data.
