Hello,

I'm trying to rotate my 2D mesh by centroid of the object. (i.e. I'm yawing it 50 degrees)

surfaceTransformPoints -rollPitchYaw (0 0 50) old.stl new.stl

Unfortunately it rotates the object by global coordinate system. Here it is:

I tried to change relevant source code below, but it seems confusing:

    else if (args.optionFound("rollPitchYaw"))
    {
        vector v(args.optionLookup("rollPitchYaw")());

        Info<< "Rotating points by" << nl
            << "    roll  " << v.x() << nl
            << "    pitch " << v.y() << nl
            << "    yaw   " << v.z() << endl;


        // Convert to radians
        v *= pi/180.0;

        quaternion R(v.x(), v.y(), v.z());

        Info<< "Rotating points by quaternion " << R << endl;
        points = transform(R, points);
    }

If you have any idea, please do not hesitate to reply.
Thank you.
