Implicit clipping plane and contour enhancement. Left: The implicit function evaluates the molecular surface (green). It takes into account only atoms that intersect the plane or lie in the half-space defined by the plane (arrows). Middle: Proteinase 3 is colored according to the amino acids, while for the clipped surface the flat shading model is employed. Right: An example of changing the width of contours.
