    I have been using Chimera to generate the Connolly surface for several
different proteins and saving the surface information in X3D format. I was
wondering what algorithms are used in the Connolly surface generation. Is it
the same approach that Michael Connolly had come up with in his 1983 paper
on Analytical Molecular Surface Calculation, or is it a variation of his
    Also, when the surface information is saved by Chimera, it breaks the
surface into triangular faces. I noticed that the  coordinates of the points
comprising the triangles are completely different from the atomic
coordinates. I am interested in learning more about how Chimera creates the
    If you could direct me to a link or paper that would help me better
understand the algorithms involved in these two processes, that would be
