class piperabm.tools.mesh.triangle.Triangle(point_1: list, point_2: list, point_3: list, density: float = 1)

Bases: object

Represent a single triangle for meshing purpose.

Parameters:

• point_1 (list) – x and y coordinates of the vertice 1.

• point_2 (list) – x and y coordinates of the vertice 1.

• point_3 (list) – x and y coordinates of the vertice 1.

• density (float, default=1) – The higher the density is, the higher the chance of containing the point is.

property area

Calculate the area of the triangle.

random_point() → list

Generate a random point inside the triangle using Barycentric coordinates.

property weight: float

Both area and density are proportional to the probability of containing a point inside. Therefore, weight is defined as a more suitable parameter for point generation.

class piperabm.tools.mesh.patch.Patch

Bases: object

A group of triangles create a patch.

add(*triangles)

Add new triangle objects to the patch.

property indexes: list

Return the list of triangle indexes.

random_point()

Generate a random point inside the patch based on the weights.

property weights: list

Return a list of weights oeganized by triangle orders.
