Elliptic geometry calculations using the disk model. Includes scripts for: Finding the point antipodal to a given point; drawing the circle with given center through a given point; measuring the elliptic angle described by three points; measuring the elliptic distance between two points; drawing the elliptic line, the elliptic line segment, and the elliptic semiline defined by two points; drawing the perpendicular to a line through a point off the line; and drawing the perpendicular to a line through a point on the line.
