Thanks very much Gunnar :

  Much appreciated ! Seems I have a knack for discovering very
cool stuff that is not documented in the RS manual . Using the
essential java search engine turned up nothing for 'Displacer'
but there were results in the Reference Manual .

  Same with the 'Constructor Field' on a the 'Spec' tab for an
SDS object . Nothing in the Manual but a very brief explanation
in the reference manual .

  There is actually an example in the menu 'Samples/Displacer'
and it shows it working , This very cool tool deserves a spot
in the Manual , I think . (the scripting example at bottom)

 Thanks again for your reply . Hope others have learned some-
thing too , about these awesome modeling methods .

cheers

function applyNoise(obj)
    {
        // create new vector object
        p = new r3Vect();

        // fetch the number of geometry points in the given object
        pcount = obj.GetPointCount();

        for(i = 0; i < pcount; i++) {
            // fetch the current value of the point 'i' 
            obj.GETPOINT(p, i);

            // displace the point using fractal noise 
            p2 = p.noise(3, 4);
            p2.fmul(0.1);
            p.fadd(p2);
            
            // set displaced point back to the object
            obj.SETPOINT(i, p);
        }
    }
