    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.

    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)

    Check if the mesh is orientable.

    TF = isOrientable(mesh)
    TF = logical
   0

    Input Arguments

    Surface mesh, specified as a surfaceMesh object.

    Output Arguments
