boundary_edges

boundary_edges(F)

Given a triangle mesh with face indices F, returns all unique oriented boundary edges as indices into the vertex array. 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
bE (be,2) numpy int array.

indices of boundary edges into the vertex array

Examples:

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