Attach a behavior to the node
defines the behavior to attach

the current Node
Adds a rotation step to the mesh current rotation. x, y, z are Euler angles expressed in radians. This methods updates the current mesh rotation, either mesh.rotation, either mesh.rotationQuaternion if it's set. This means this rotation is made in the mesh local space only. It's useful to set a custom rotation order different from the BJS standard one YXZ. Example : this rotates the mesh first around its local X axis, then around its local Z axis, finally around its local Y axis.
mesh.addRotation(x1, 0, 0).addRotation(0, 0, z2).addRotation(0, 0, y3);
Note that addRotation() accumulates the passed rotation values to the current ones and computes the .rotation or .rotationQuaternion updated values.
Under the hood, only quaternions are used. So it's a little faster is you use .rotationQuaternion because it doesn't need to translate them back to Euler angles.
