Open Source Java Physics Software

Multibody dynamics simulation package with frictional contact and collision detection

Create a sun, spin some asteroids around it, and watch them collide and form planets. An N-Point Gravity Simulator is a realistic simulation in which all points attract each other: even the smallest asteroid has its own gravitational field that can affect even a large sun far away from it. Can be reused as a library for making games. If used as library, license is GNU LGPLv3, otherwise it's GNU GPLv3.

Worldlines visualizes special relativity, as particles near lightspeed trace paths in a 3D slice of 4D Minkowski spacetime. Scenes illustrate time dilation, the twin paradox, length contraction, and Bell's spaceship paradox.

Physics simulation toys in Java. The focus is on systems simulation:mostly guidance/navigation systems, but also including hydraulic, electrical and life-support.

Bloft (BLObby and sOFT) is a real-time soft-body physics simulator optimized for real-world mobile phones. It is written in Java and uses fixed-point math only. Memory allocations are minimized to suite the needs of JVMs in older mobile phones.

JOODE, the Java Object Orientated Dynamics Engine. This project is a port of the popular open source physics engine ODE. see http://www.javagaming.org/forums/index.php?board=11.0

JPhysics is library for simulation physics written in Java.

With Physicssite one can build two-dimensional, rigid-body-physics-based simulations. It's written in Java and uses the physics engine JBox2D.

This is the Official Software of the Pi-Space Physics Theory created by Martin Brady. I have a B.Sc. in Computer Applications from Dublin City University and I have an interest in software implementation of Physics. The Theory includes a Quantum Theory of Gravity as well as a reworking of Classical versions of Newton's Formulas. The Theory is based on a set of Relativistic Diagrams called Pi-Space Diagrams for those new to the Theory.

A Java library that works with Java3D to simulate and visualize, in real-time, dynamics of multiple rigid bodies that are restricted by implicit and explicit constraints (e.g., robotics); designed for efficiency, ease-of-use, and extensibility.

Simulation of star movements with great visualizations of flights through star fields.

The Vehicle Maneuver Simulator lets you simulate the maneuvering of simple and complex vehicles with different numbers of wheels, axles and joints.

A web-distributed 3D virtual universe for modellers, developers, scientists, gamers and social networkers. Pluggable visualization engines, navigation (vehicle/avatar) controls, model editors, scene editors, messaging.

You play a 2d blob that reshapes to grab bend bounce and swing on objects floating in midair (like a platformer game), except acrobaticly your view spins when your blob does. I'm planning a huge multiplayer world, some blobs played by people holding a bendable loop game controller (tape a 1 meter cut of thick extension cord into a loop) in front of webcam and bend it to bend your blob on screen, and other blobs controlled by AI. This is a game for general AI research in a fun way people can do together. The physics and vision algorithm is half working in version 0.3.0. The gameplay is better experienced in 0.2 which is controlled with the mouse so you dont have enough freedom of movement compared to webcam. This small file contains its own source code including occamserver, a tiny general java server I built which I'll adjust to allow http streaming connections to stay open for faster ajax than a new web call each time. The reshaping and bouncing physics is by springs.
