From: \scene\language\trace2.pov
Add: #include "transforms.inc" // at the top of the scene
about line 64

    //cylinder {iPt, iPt + iNorm*PinHeight, 0.01}
    cylinder {0,<0,PinHeight,0>, 0.01
     Reorient_Trans(<0,1,0>, iNorm)
     translate iPt   //<iPt.x,iPt.y,iPt.z>
    }

I have replaced the original cylinder{} with one defined at the origin and
rotated to match the normal, then translated into place.

Is this what you where looking for?
