Node.js bindings to Bullet Physics through node-ffi

node-bullet

Node.js bindings to Bullet Physics through node-ffi.

These bindings are automatically generated via node-ffi-generate from the Bullet C API header file (Bullet-C-Api.h). They have a 1:1 mapping with the existing Bullet C API documentation.

Installing this library via NPM

Currently, this library is not published to npm. However, you can use it in npm projects by adding it to your package.json using a git url:

"dependencies": { 
  "bulletphysics": "git://github.com/psigen/node-bulletphysics.git"
}

Example Usage

var bullet = require('bulletphysics').bullet;
var sdk = bullet.plNewBulletSdk();
...
console.log('Doing Bullet stuff...');
...
bullet.plDeletePhysicsSdk(sdk);

Compilation notes

• By default, BT_DOUBLE_PRECISION is enabled, because I need it. It can be disabled by editing the defines in (binding.gyp)[binding.gyp].
• During node-gyp, the tarball in src is extracted to src/bullet. If you want to mess with the bullet source before compiling, just put your own source code in that directory.
• Some functions from the C API were removed, as they had no actual implementation in the source code. They are commented out in bulletphysics.js
• GPU accelerated functions were not compiled, since they add a dependency on OpenCL that I didn't want to handle.
