Geometry.CircularStringZ
(Geometry v1.2.0)
View Source
A circular-string struct, representing a 3D curve.
A non-empty circular-string requires at least three coordinates. In a sequence of arcs the end point of the previous arc is the start point of the next arc, just like the segments of a LineString. This means that a CircularString must have an odd number of points greater than 1.
Summary
Functions
Creates an empty CircularStringZ.
Creates a CircularStringZ from the given Geometry.PointZs.
Types
@type t() :: %Geometry.CircularStringZ{arcs: Geometry.arcs(), srid: Geometry.srid()}
Functions
@spec new() :: t()
Creates an empty CircularStringZ.
Examples
iex> CircularStringZ.new()
%CircularStringZ{arcs: [], srid: 0}@spec new([Geometry.PointZ.t()], Geometry.srid()) :: t()
Creates a CircularStringZ from the given Geometry.PointZs.
Examples
iex> CircularStringZ.new(
...> [PointZ.new(1, 2, 3), PointZ.new(3, 4, 5), PointZ.new(5, 6, 7)])
%CircularStringZ{arcs: [[1, 2, 3], [3, 4, 5], [5, 6, 7]], srid: 0}
