module Geom2D

Geom2D - Objects and Algorithms for 2D Geometry in Ruby ↑

This library implements objects for 2D geometry, like points, line segments, arcs, curves and so on, as well as algorithms for these objects, like line-line intersections and arc approximation by Bezier curves.

Public Class Methods

Point(x, y = nil) click to toggle source

Creates a new Point object from the given coordinates.

See: Point.new

# File lib/geom2d.rb, line 31
def self.Point(x, y = nil)
  if x.kind_of?(Point)
    x
  elsif y
    Point.new(x, y)
  else
    Point.new(*x)
  end
end
Polygon(*vertices) click to toggle source

Creates a new Polygon object from the given vertices.

See: Polygon.new

# File lib/geom2d.rb, line 58
def self.Polygon(*vertices)
  Polygon.new(vertices)
end
PolygonSet(*polygons) click to toggle source

Creates a PolygonSet from the given array of Polygon instances.

See: PolygonSet.new

# File lib/geom2d.rb, line 65
def self.PolygonSet(*polygons)
  PolygonSet.new(polygons)
end
Segment(start_point, end_point = nil, vector: nil) click to toggle source

Creates a new Segment from start_point to end_point or, if vector is given, from start_point to start_point + vector.

See: Segment.new

# File lib/geom2d.rb, line 45
def self.Segment(start_point, end_point = nil, vector: nil)
  if end_point
    Segment.new(start_point, end_point)
  elsif vector
    Segment.new(start_point, start_point + vector)
  else
    raise ArgumentError, "Either end_point or a vector must be given"
  end
end
