Bullet (Bullet Physics SDK) is an Open Source collision detection and rigid body dynamics library. The Library is free for commercial use and open source under the ZLib License.

From Bullet's main project page:

Bullet 3D Game Multiphysics Library provides state of the art collision detection, soft body and rigid body dynamics.

  • Used by many movie and game companies in AAA titles on Playstation 3, XBox 360, Nintendo Wii, PC and iPhone
  • Modular extendible C++ design with hot-swap of most components
  • Optimized back-ends for pthreads/Win32 Threads multi-threading and PS3 Cell SPU
  • Preparation for OpenCL data parallel optimizations for upcoming Bullet 3.x

Bullet Collision Detection can be used on its own as a separate SDK without Bullet Dynamics

  • Discrete and continuous collision detection (CCD)
  • Swept collision queries
  • Ray casting with custom collision filtering
  • Generic convex support (using GJK), capsule, cylinder, cone, sphere, box and non-convex triangle meshes.
  • Support for dynamic deformation of non-convex triangle meshes, by refitting the acceleration structures

Multi-physics support including:

  • Rigid body dynamics including constraint solvers, generic constraints, ragdolls, hinge, ball-socket
  • Support for constraint limits and motors
  • Soft body support including cloth, rope and deformable
  • Bullet is integrated into Cinema 4D, Lightwave, Blender and Carrara, and plugins for Maya, Houdini and 3ds Max are available
  • Serialization of physics data in the cross-platform binary .bullet file format

The Library is free for commercial use and open source under the ZLib License.

Apply physics to player using bullet physics

So I've had a lot of problems trying to properly get physics applied to the play by using bullet physics. I've tried kinematic bodies to an unsuccess. I am now trying now trying to use a rigid body I've had little successfully. Pasted below is the…

Bullet Physics - cutting a hole in the geometry

I have a static rigid body created with btBvhTriangleMeshShape. This rigid body will be a room. Now I'm making a portal (teleport) on the floor. Due to this portal there should be a hole in the geometry of the static object. I dont know if it is…

How would I go about applying physics to the player with bullet?

I've been trying to apply physics to the player controlled character and have come up with nothing. I've followed the demo and have created a character controller. From here though updating my camera's position and the controller's doesn't seem to…

Character stuck underneath world

So I've been able to use bullet physics to bind a rigid body to a cube and have it fall while being rendering, but when I tried to "attach" a rigid body to the player it got the player stuck underneath the world, unable to move. I was originally…

Is physics simulation really faster on GPU?

From what i have observed, havok does a significantly better job for rigid simulation than Physx, especially their new Havok Physics 2013. Im not very familiar with how state of the art physics engine works, but by testing alone i cannot get a very…

JOGL Jar runs fine on my development machine, but slowly on others? Even if they have better hardware

I am currently messing around with JOGL and JBullet with some success. I'd like to share what I've created with my friends. I created a jar file and a .bat to open it with the argument -Dsun.java2d.noddraw=true. The jar runs perfectly on my machine.…

What replaced BulletSharp.ContactAdded?

I recently updated my project's physics library (BulletSharp) from 2.80 to 2.82 and I was left with a bunch of invalid calls (had around 20 build errors in the debug drawer). I've fixed nearly all of them apart from a collision detection call. From…

Extremely bizzare issue with Bullet physics

I am using bullet physics with my project. I used to compile it and my project with Visual C++, and everything worked fine. But I'm getting an extremely bizzare issue when now using Code::Blocks instead. When I switched over, I rebuilt the bullet…
