Structs

ChordAngle

ChordAngle represents the angle subtended by a chord (i.e., the straight line segment connecting two points on the sphere). Its representation makes it very efficient for computing and comparing distances, but unlike Angle it is only capable of representing angles between 0 and π radians. Generally, ChordAngle should only be used in loops where many angles need to be calculated and compared. Otherwise it is simpler to use Angle.

Constants

NEGATIVE

NEGATIVE represents a chord angle smaller than the zero angle. The only valid operations on a NegativeChordAngle are comparisons and Angle conversions.

RIGHT

RIGHT represents a chord angle of 90 degrees (a "right angle").

STRAIGHT

STRAIGHT represents a chord angle of 180 degrees (a "straight angle"). This is the maximum finite chord angle.
