Physics And Dynamics Links
From K-3D
Open Dynamics Engine
ODE is a free, industrial quality library for simulating articulated rigid body dynamics - for example ground vehicles, legged creatures, and moving objects in VR environments. It is fast, flexible, robust and platform independent, with advanced joints, contact with friction, and built-in collision detection.
Bullet Continuous Collision Detection and Physics Library
Bullet is an alternative to ODE.
Yet Another Dynamics Engine
Yade is an extensible GNU/GPL framework designed with dynamic libraries in a way that it is easy to add new numerical models and objects. Another possible alternative to ODE.
Virtual Terrain Project
The goal of VTP is to foster the creation of tools for easily constructing any part of the real world in interactive, 3D digital form.
The Gerris Flow Solver
Gerris is an Open Source Free Software library for the solution of the partial differential equations describing fluid flow.
Gmsh
A three-dimensional finite element mesh generator with built-in pre- and post-processing facilities
Atmosphere
A fascinating page devoted to realistic rendering of the sky.
