"matereal" project moved its official site to http://mr.digitalmuseum.jp/.
"matereal" is a useful toolkit that allows to operate home-robots (like LEGO Mindstorm NXT, Roomba, NetTansor etc.) easily on Java/Processing environment. It runs on Windows, Mac OSX and hopefully on Linux(not tested). This project contains two sub-projects, "capture" and "napkit".
"capture" is a cross-platform library that uses DirectShow on Windows, QuickTime on Mac OSX and Java Media Framework on Linux to capture images with webcams. This library can be used independently without "matereal".
"napkit" is a wrapper library of NyARToolkit that can be easily used with "capture". Some part of this library is distributed under GPLv3 due to ARToolKit license restriction. This library also extends "matereal" to detect absolute positions of robots with visual markers.
