ladybug_geometry.util module

Utility functions used by several different geometry methods.

ladybug_geometry.util.coordinates_hash(point, tolerance)

Convert XY coordinates of a Point2D into a string useful for hashing.

Points that are co-located within the tolerance will receive the same string value from this function, which helps convert line segments that contain duplicated vertex references them into a singular network object where co-located vertices are referenced only once.

Parameters:

• point – A Point2D object.

• tolerance – floating point precision tolerance.

Returns:

A string of rounded coordinates.

ladybug_geometry.util.coordinates_hash_3d(point, tolerance)

Convert XY coordinates of a Point3D into a string useful for hashing.

Points that are co-located within the tolerance will receive the same string value from this function, which helps convert line segments that contain duplicated vertex references them into a singular network object where co-located vertices are referenced only once.

Parameters:

• point – A Point3D object.

• tolerance – floating point precision tolerance.

Returns:

A string of rounded coordinates.
