Open Dynamics Engine
Overview
 
The Open Dynamics Engine (ODE) is a physics engine
Physics engine
A physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics , soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film. Their main uses are in video games , in which case the...

 in C/C++. Its two main components are a rigid body dynamics
Rigid body dynamics
In physics, rigid body dynamics is the study of the motion of rigid bodies. Unlike particles, which move only in three degrees of freedom , rigid bodies occupy space and have geometrical properties, such as a center of mass, moments of inertia, etc., that characterize motion in six degrees of...

 simulation engine and a collision detection
Collision detection
Collision detection typically refers to the computational problem of detecting the intersection of two or more objects. While the topic is most often associated with its use in video games and other physical simulations, it also has applications in robotics...

Free software
Free software, software libre or libre software is software that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with restrictions that only ensure that further recipients can also do...

ODE was started in 2001 and has already been used in many applications and games, such as BloodRayne 2
BloodRayne 2
BloodRayne 2, developed by Terminal Reality, is a third-person horror-themed action-adventure video game and the second game in the BloodRayne series. It does not follow on directly from where BloodRayne finished; instead, it takes place 60 and 70 years later in a contemporary 2000s...

X-Moto
X-Moto is a free and open source 2D motocross platform game developed for Linux, FreeBSD, Mac OS X and Microsoft Windows, where physics play an all important role in the gameplay. The basic gameplay clones that of Elasto Mania, but the simulated physics are subtly different. The project was started...
