collapsible

property Halfedge.collapsible

Topological state.

A edge joining non-boundary vertices of a triangle mesh is collapsible if the neighborhoods of origin and target vertex intersect in the two vertices opposite the query edge. The test tries to handle meshes with higher valence faces but may not always give a correct answer.

Type:

bool

Note

For technical reasons, boundary halfedges are always classified as non-collapsible.
