public static com.jme3.math.Transform convert(com.bulletphysics.linearmath.Transform in,  com.jme3.math.Transform out) {
        convert(in.origin, out.getTranslation());
        convert(in.basis, out.getRotation());
        return out;
    }
Nice convenience methods for conversion between javax.vecmath and com.jme3.math
Objects, also some jme to jbullet mesh conversion.
