Exact visibility calculation for space-filling molecular models.
The visible portion of two intersecting atoms is exactly calculated to be bounded by a circular arc and an elliptic arc. The elliptic arc can be approximated either by a circular arc or by a cubic Bezier curve. Using one shaded template for each atom type and stamping the templates in a mask bitmap delineated by these curves, images are generated rapidly.
