isOrientable

Check if surface mesh is orientable

Since R2020b

Syntax

TF = isOrientable(mesh)

Description

TF = isOrientable(mesh) checks if the surface mesh is orientable. The orientation of a mesh is given by the cyclic order of its vertices. A mesh is orientable if all its face normals point outside.

Check If Surface Mesh Is Orientable

Open Live Script

Read a surface mesh from an STL file.

fileName = fullfile(toolboxdir("lidar" ),"lidardata", ...
                  "surfaceMesh","mobius.stl");
mesh = readSurfaceMesh(fileName);

Display the surface mesh

surfaceMeshShow(mesh,Title="Input Mesh")

Check if the mesh is orientable.

TF = isOrientable(mesh)

TF = logical

Input Arguments

`mesh` — Surface mesh
`surfaceMesh` object

Surface mesh, specified as a surfaceMesh object.

Output Arguments

collapse all

`TF` — Surface mesh is orientable
`0` | `1`

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