Build Status

ode4j is a Java port of ODE.

ODE is an open source, high performance library for simulating rigid body dynamics. It is fully featured, stable, mature and platform independent with an easy to use C/C++ API. It has advanced joint types and integrated collision detection with friction. ODE is useful for simulating vehicles, objects in virtual reality environments and virtual creatures. It is currently used in many computer games, 3D authoring tools and simulation tools.

The latest released version of ode4j is 0.4.0, but the master branch contains numerous fixes and improvements. Version 0.2.4 up to 0.2.9 are ports of ODE 0.12.1, Version 0.3.1 is a port of ODE 0.13.1. Release 0.4.0 Contains most changes between 0.13.1 and 0.16.0.

ode4j contains also some features that are not present in ODE, such as a ragdoll and heightfields with holes. See Wiki.

The ODE forum is useful for questions around physics and general API usage:

There is a new Discord channel around ode4j/Java.

The ode4j forum is for problems and functionality specific to ode4j/Java.

There is also the old website, including some screenshots.

The following artifact contains the complete physics engine (examples etc are not included):



2019-01-03: Release 0.4.0. This release contains most of the changes that happened between ODE 0.13.1 and ODE 0.16.0, plus some original features:

  • Java 9 / modularization (generated jar files are Java 7) (io7m)
  • Implemented/migrated multi-threading for the stepper (Pjotr)
  • SAP-Space optimization: Avoid collision detection for immobile bodies (Pjotr)
  • New BVH tree for better scalability with 10'000 bodies or more, ported from the Turbulenz Engine (Pjotr)
  • Fixed javadoc to compile without warnings

2018-03-26: Snapshot release 0.4.0

  • Java 9 / modularization (generated jar files are Java 7) (io7m)

2017-11-16: Snapshot release 0.4.0

2017-10-06: Release of ode4j 0.3.1

  • Numerous bugfixes and improvement, see CHANGELOG
  • This is the last release built with Java 6.
