Visualization of graph components. Left: The iso-surface point (the black circle), obtained during ray-casting, is evaluated against the distance (the dashed line) to the graph component (the black line). Right: An example of graph component visualization in the context of the molecule. When a graph component is shown, the coloring is applied only to points that lie within distance Dg = 3R from the graph. We employ flat shading for surface points lying beyond Dg. The boundary of Dg is shown as a black contour on the surface. The graph component is displayed using line segments (edges) and spheres (nodes).
