Attributes
---------
points: tuple or list of tuples
Points defining stroke lines.
style: str
Single character defining style of stroke. Default values are:
'm' for mountain creases
'v' for valley creases
'e' for edge borders
Extra possible values:
'u' for universal creases
's' for semicreases
'c' for kirigami cuts
angle: float
From 0 to 180 degrees, converted to an opacity level from 0 to 1. This is how OrigamiSimulator encodes maximum
fold angles
closed: bool
Tells if desired path should contain a last stroke from the last point to the first point, closing the path
radius: float
If only one point is given, it's assumed to be a circle and radius sets the radius
Methods
---------
invert(self)
Inverts path
Overloaded Operators
---------
__add__(self, offsets)
Adding a tuple to a Path returns a new path with all points having an offset defined by the tuple
__mul__(self, transform)
Define multiplication of a Path to a vector in complex exponential representation
Static Methods
---------
draw_paths_recursively(path_tree, group, styles_dict)
Draws strokes defined on "path_tree" to "group". Styles dict maps style of path_tree element to the definition
of the style. Ex.:
if path_tree[i].style = 'm', styles_dict must have an element 'm'.
generate_hgrid(cls, xlims, ylims, nb_of_divisions, style, include_edge=False)
Generate list of Path instances, in which each Path is a stroke defining a horizontal grid dividing the space
xlims * ylims nb_of_divisions times.
generate_vgrid(cls, xlims, ylims, nb_of_divisions, style, include_edge=False)
Generate list of Path instances, in which each Path is a stroke defining a vertical grid dividing the space
xlims * ylims nb_of_divisions times.
generate_separated_paths(cls, points, styles, closed=False)
Generate list of Path instances, in which each Path is the stroke between each two point tuples, in case each
stroke must be handled separately
reflect(cls, path, p1, p2)
Reflects each point of path on line defined by two points and return new Path instance with new reflected points
list_reflect(cls, paths, p1, p2)
Generate list of new Path instances, rotation each path by transform
list_rotate(cls, paths, theta, translation=(0, 0))
Generate list of new Path instances, rotation each path by transform
list_add(cls, paths, offsets)
Generate list of new Path instances, adding a different tuple for each list
list_mul(cls, paths, transf)
Generate list of new Path instances, multiplying a different tuple for each list
list_simplify(cls, paths)
Gets complicated path-tree list and converts it into
a simple list.
list_invert(cls, paths)
Invert list of paths and points of each path.
debug_points(cls, paths):
Plots points of path tree in drawing order.

<label>"Waterbomb tessellation" creates a simple tessellation pattern repeating the Waterbomb base, with a half-step phase shift between each line.
The Magic ball is a different design that inverts both the upper half of the first line and the bottom half of the last line.</label>
