Scythe Physics Editor

Scythe is a free software physics modeling program. It allows the merging of physics and graphics content in one package. It provides native support for modeling the rigid body physics for the Newton Game Dynamics, the Open Dynamics Engine and PhysX engine. The Physics Abstraction Layer also provides support for the Scythe format.

History
The Scythe Physics Editor was first developed as closed source software in 2006. It was released as open source software with a GNU General Public License in September 2007, after the developers decided to focus activities on a new game.
