isVertexManifold

Check if surface mesh is vertex-manifold

Since R2022b

Syntax

TF = isVertexManifold(mesh)

Description

TF = isVertexManifold(mesh) checks if the surface mesh is vertex-manifold. A mesh is vertex-manifold if faces with a common vertex form an open or closed fan.

Examples

Check If Surface Mesh Is Vertex-Manifold

Define mesh vertices and faces for the surface mesh.

vertices = [0 0 0; 0 0 1; 0 1 1; 0 0 2; 1 0.5 1];
faces = [1 2 3; 2 3 4; 2 3 5];

Create and display the surface mesh.

mesh = surfaceMesh(vertices,faces);
surfaceMeshShow(mesh)

Check if the mesh is vertex-manifold.

TF = isVertexManifold(mesh)

TF = logical
   1

Input Arguments

mesh — Surface mesh

surfaceMesh object

Surface mesh, specified as a surfaceMesh object.

Output Arguments

TF — Surface mesh is vertex-manifold

0 | 1

Surface mesh is vertex-manifold, returned as a logical 0 (false) or 1 (true). The function returns true when the mesh is vertex-manifold. Otherwise, it returns false.
