boolean_union_mesh_mesh

compas.geometry.boolean_union_mesh_mesh(A, B)[source]

Compute the boolean union of two triangle meshes.

Parameters:

Atuple[sequence[point], sequence[[int, int, int]]]: The vertices and faces of mesh A.
Btuple[sequence[point], sequence[[int, int, int]]]: The vertices and faces of mesh B.

Returns:

tuple[list[point], list[[int, int, int]]]: The vertices and the faces of the boolean union.

Notes

This function is a “pluggable”. This means that it doesn’t provide an implementation, but receives an implementation from a corresponding “plugin”. To use the plugin implementation, you have to install it in the same environment as COMPAS. One such plugin is available in compas_cgal.

Examples

>>> from compas.geometry import Box, Sphere
>>> from compas.geometry import boolean_union_mesh_mesh     
>>> from compas.geometry import trimesh_remesh              
>>> from compas.datastructures import Mesh

>>> box = Box.from_width_height_depth(2, 2, 2)
>>> box = Mesh.from_shape(box)
>>> box.quads_to_triangles()

>>> sphere = Sphere([1, 1, 1], 1)
>>> sphere = Mesh.from_shape(sphere, u=30, v=30)
>>> sphere.quads_to_triangles()

>>> A = box.to_vertices_and_faces()
>>> B = sphere.to_vertices_and_faces()
>>> B = trimesh_remesh(B, 0.3, 10)                          

>>> V, F = boolean_union_mesh_mesh(A, B)                    
>>> union = Mesh.from_vertices_and_faces(V, F)
