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.

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