Class methods
distanceWithFirstPoint:secondPoint:
|
+ (double)distanceWithFirstPoint:(nonnull MMKPoint *)firstPoint |
Calculate the great-circle distance between two points on a sphere with a radius equal to the Earth's radius using the haversine formula described here: http://en.wikipedia.org/wiki/Haversine_formula
This formula is numerically better-conditioned for small distances, according to http://en.wikipedia.org/wiki/Great-circle_distance
closestPointWithPoint:segment:
|
+ (nonnull MMKPoint *)closestPointWithPoint:(nonnull MMKPoint *)point |
Find the point on a given segment (great-circle arc or shorter arc) that is closest to a given point.
pointOnSegmentByFactorWithSegment:factor:
|
+ (nonnull MMKPoint *)pointOnSegmentByFactorWithSegment: |
Find a point X on a given segment AB such that d(AX)/d(AB) = factor, where factor is a given number in [0, 1].
courseWithFirstPoint:secondPoint:
|
+ (double)courseWithFirstPoint:(nonnull MMKPoint *)firstPoint |
Calculate the course (bearing) between two points in degrees in the range [0, 360].
