boundary_vertices

boundary_vertices(F)

Given a triangle mesh with face indices F, returns the indices of all boundary vertices. Works only on manifold meshes.

Parameters:

Name Type Description Default
F (m,3) numpy int array

face index list of a triangle mesh

 required

Returns:

Name Type Description
bV (bv,) numpy int array

list of indices into F of boundary vertices

Examples:

from gpytoolbox import read_mesh, boundary_vertices
v,f = read_mesh("test/unit_tests_data/bunny_oded.obj")
bv = boundary_vertices(f)
