I'm looking for a physics engine to use in an XNA project (2D or 3D). Because it's for XNA, it needs to fulfill some requirements:

  1. Not necessarily free, but close to it is obviously preferred
  2. Managed code only (or it won't run on the 360)

For 3D I know of - BulletX (It works, and I'm using it now, but it's not active and could use more work)

For 2D I know of - Farseer

2D

  • Farseer is based on box2d but has lot of its own improvements and innovations.
  • Box2Dx & Box2D.Xna are both ports of box 2D
  • i think theres a port of chipmunk physics out there, but i cant find the link

3D

  • JigLib one of the earliest 3d physics engines for xna, been used quite a bit
  • Jitter Quite a new engine, but more per formant than JigLib
  • Henge3D A newer engine to the scene, impressive multi-threading

I've used Farseer for XNA and it worked great. Comes with lots of example code as well so you can see it in action and has pretty good documentation.

Somehow managed to miss that in your list. –  Casey Jul 15 '10 at 0:16

For a 3D physics library, BEPU physics has just recently became free for both commercial and non-commerical use.

+1, BEPU is excellent now that it's open source. –  Olhovsky Jun 6 '11 at 1:32

Henge3D has been my library of choice. What sold me was the price (free) and the multi-threading capabilities.

There is a Box2D C# version called Box2DX. Since it's free and I know Box2D is good, it is probably worth it to check out.
