The Technology Behind Mammoth

■ Written completely in Java (5.0). Most developers use Eclipse to work on Mammoth.

Build is managed by Ant.

■ Code is store in a SVN repository Automated build validation using CruiseControl

■ Many existing libraries are used to simplify Mammoth development: JMonkeyEngine / FengGUI

Pastry / Scribe (in development)

JTS Topology Suite

JGraphT

Triangles

Log4J
