Mesh3D.remove_degenerate_triangles() -> flat triangle not taken into account

• I'm submitting a ...

  • bug report
  • feature request

• What is the current behavior?
  I have a triangle from a STL with 3 points aligned and it is not delete by remove_degenerate_triangles method

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem Avoid reference to other packages

Those are my points aligned:
point1: Point3D(-0.6205590209960937, 0.349411376953125, 0.17962226867675782)
point2: Point3D(-0.6205590209960937, 0.349411376953125, 0.407595458984375)
point3: Point3D(-0.6205590209960937, 0.349411376953125, 0.384592529296875)

• What is the expected behavior?
  Aligned point to be deleted OR method Mesh3D.to_triangles3d to not fail because of those three aligned points

• What is the motivation / use case for changing the behavior?
  Customer

• Possible fixes
  Check with normalize vector in order to verify that they are not aligned

• Please tell us about your environment:

  • branch: master
  • commit: latest
  • python version: 3.9.13

Another possiblity is to put a try except:
def to_triangles3d(self):
"""
Export the mesh faces as Triangle3D objects.

    :return: The triangles comosing the mesh.
    :rtype: list[Triangle3D]
    """
    # pylint: disable=import-outside-toplevel, cyclic-import
    from volmdlr.faces import Triangle3D

    triangles3d = []
    for vertex1, vertex2, vertex3 in self.remove_degenerate_triangles(tol=1e-6).triangles_vertices():
        point1 = volmdlr.Point3D(*vertex1)
        point2 = volmdlr.Point3D(*vertex2)
        point3 = volmdlr.Point3D(*vertex3)

        try:
            triangles3d.append(Triangle3D(point1, point2, point3))
        except ZeroDivisionError:
            continue

    return triangles3d
