Best Physics library?
nattydread commented on 7 March 2017 at 1:02 pm UTC

I am thinking about writing some code for 3D rag-dolls. Does anyone here have experience with physics libraries? What are the pro's and cons? Do you know of example projects or source code? I'm considering bullet or ODE, are they any good?

Thank you for your question I've always been curious about physics simulation.

Have never integrated a physics engine myself, but it seems to require some pretty solid understanding of the specific math behind it an many floating point precision issues.

From what I have gathered over the years from various discussions is that ODE is a bit easier to integrate initially, but bullet works better once you have it running.

If you just want ragdolls, a full physics simulation is overkill by the way. The Sauerbraten game includes a simplified ragdoll simulation code that works great and is very fast.

Hi Julius,
Thanks for your reply, I'll take a look at the Sauerbraten code, I hadn't realised that there were any open-source games with rag-dolls yet.

I'll explore ODE a bit more too, I am interested in the full physics.
Or I might write my own code from scratch, I found a good book
"Game Physics Engine Development How to Build a Robust Commercial-grade Physics Engine for Your Game"


Ian Millington

that includes a bare source code to build upon.

I'll update if I make any serious progress!

Thanks again,
