Processing

Open Source software
Derived from Java
Many available examples
Many contributed libraries: for Arduino, 3DObject,
QRCode, Box2D for games, Open Computer Vision,
for Augmented Reality like NyAR4psg or NyAR2, etc.

U

Marker augmented reality
(NyAR4psg, NyAR2 libraries)
Loading 3D objects
Markerless augmented reality
(Saito OBJLoader library)
(OpenCV library)

Lego robots
(NTXcomm library)

QR code library

Data communication
(libraries for SMS,
SQL databases,…)

Games (pBox2D library)

Machine learning
(Gnet library)
Arduino library

We need extra libraries and programs to start executing
augmented reality code with Processing:
• Libraries
 GSVideo
http://sourceforge.net/projects/gsvide
o/files/gsvideo/1.0

• Programs
 QuickTime
http://www.apple.com/es/quicktime/d
ownload/

 OBJLoader

https://code.google.com/p/saitoobjloader/
 Nyar4psg-1.3.1

http://sourceforge.jp/projects/nyartoolkit/
releases/?package_id=8920

 WinVDIG

WHERE WE HAVE TO PUT THE
EXTRA PROGRAMS
Programs: At the same folder than processing
