Create CANNON.RigidBody from THREE.Mesh or THREE.Geometry

Question

I am creating a THREE.Mesh object using a THREE.JSONLoader object like so:

// Create castle.
loader.load(\'/Meshes/CastleTower.js\'         


        

Answer 1

I had a similar issue and created the necessary "points" and "faces" (as described in Cannon docs) from the THREE.Geometry (called geometry here) with these two functions:

cannonPoints = geometry.vertices.map(function(v) {
    return new CANNON.Vec3( v.x, v.y, v.z )
})

cannonFaces = geometry.faces.map(function(f) {
    return [f.a, f.b, f.c]
})
