Babylon seems to be left handed like DirectX, cannon is right handed like openGL, how is this working ?

[altreality]

In the babylon.physicsEngine.js file I see that the z and the y have been interchanged. I guess thats because cannon has z axis up and not y axis like Babylon. 

 

But shouldnt  z or y have their sign changed also to take care of the handedness.

 

I ask because cannon has added heightmap support and I want to adapt the following code for supporting the heightmaps in babylon from cannon :

 

 CannonJSPlugin.prototype._createConvexPolyhedron = function (rawVerts, rawFaces, mesh, options) {            var verts = [], faces = [];            mesh.computeWorldMatrix(true);            for (var i = 0; i < rawVerts.length; i += 3) {                var transformed = BABYLON.Vector3.Zero();                BABYLON.Vector3.TransformNormalFromFloatsToRef(rawVerts[i], rawVerts[i + 1], rawVerts[i + 2], mesh.getWorldMatrix(), transformed);                verts.push(new CANNON.Vec3(transformed.x, transformed.z, transformed.y));            }            for (var j = 0; j < rawFaces.length; j += 3) {                faces.push([rawFaces[j], rawFaces[j + 2], rawFaces[j + 1]]);            }            var shape = new CANNON.ConvexPolyhedron(verts, faces);            if (!options) {                return shape;            }            return this._createRigidBodyFromShape(shape, mesh, options.mass, options.friction, options.restitution);        };

Hello from the test I did inverting y and z was enough

 

Is it not working for you? (Happy to see heightmap support added:))
