plcurve: Piecewise-Linear Curves (a.k.a. Polygons)¶
The PlCurve class¶
-
class
libpl.plcurve.PlCurve¶ It’s a PlCurve.
Create a new PlCurve, optionally with empty components described by
component_spec.If it is not
None,component_specis a sequence of the form (int num_vertices, bool open, int num_colors).-
add_component(component)¶ Add a component to this PlCurve.
-
center_of_mass¶ Center of mass.
-
fix_wrap()¶
-
gyradius¶ Gyradius of this PlCurve.
-
num_edges¶ Number of edges in this PlCurve.
-
num_vertices¶ Number of vertices in this PlCurve.
-
perturb¶ Randomly perturb this PlCurve
-
pointset_diameter¶ Diameter of the points
-
projection_to_PlanarDiagram(RandomGenerator rng) → new PlanarDiagram¶ Creates a new PlanarDiagram from a projection of this PlCurve.
-
random_closed_plane_polygon(int n_edges, RandomGenerator rng) → PlCurve¶ Create a random closed plane polygon.
-
random_closed_polygon(int n_edges, RandomGenerator rng) → PlCurve¶ Create a random closed polygon.
-
random_equilateral_closed_polygon(int n_edges, RandomGenerator rng) → PlCurve¶ Generate a random equilateral polygon using the CSU algorithm.
-
random_equilateral_open_polygon(int n_edges, RandomGenerator rng) → PlCurve¶ Create a random equilateral open polygon.
