Longitude wrapping logic in the upload below was faulty and produced nonsensical graphics when the Sun moved into the geocentric northern celestial hemisphere last month.  Corrections to faulty logic are documented in the attached "R1" PDF which completely supersedes the "R0" draft uploaded last October.

Subject: Surface Map Terminator Graphics

ATIG Members-

A brief description of an algorithm plotting a terminator (day/night line) on a celestial body's surface is attached.  Because atmospheric and terrain effects are neglected, the algorithm assumes a spherical surface for simplicity.  Comments and questions on this topic are welcome.
