.. py:module:: rhino3dm

.. py:class:: MeshVertexList

   .. py:attribute:: UseDoublePrecisionVertices

      bool: Set to True if the vertices should be stored in double precision

   .. py:method:: SetCount()

      [todo] add documentation

   .. py:method:: __getitem__()

   .. py:method:: Clear()

      Clears the Vertex list on the mesh.


      :rtype: void

   .. py:method:: Destroy()

      Releases all memory allocated to store faces. The list capacity will be 0 after this call.
      Subsequent calls can add new items.


      :rtype: void

   .. py:method:: Add(x, y, z)

      Adds a new vertex to the end of the Vertex list.

      :param float x: X component of new vertex coordinate.
      :param float y: Y component of new vertex coordinate.
      :param float z: Z component of new vertex coordinate.

      :return: The index of the newly added vertex.

      :rtype: int

   .. py:method:: IsHidden(vertexIndex)

      Gets a value indicating whether or not a vertex is hidden.

      :param int vertexIndex: Index of vertex to query.

      :return: True if the vertex is hidden, False if it is not.

      :rtype: bool

   .. py:method:: Hide(vertexIndex)

      Hides the vertex at the given index.

      :param int vertexIndex: Index of vertex to hide.


      :rtype: void

   .. py:method:: Show(vertexIndex)

      Shows the vertex at the given index.

      :param int vertexIndex: Index of vertex to show.


      :rtype: void

   .. py:method:: HideAll()

      Hides all vertices in the mesh.


      :rtype: void

   .. py:method:: ShowAll()

      Shows all vertices in the mesh.


      :rtype: void

   .. py:method:: CullUnused()

      Removes all vertices that are currently not used by the Face list.

      :return: The number of unused vertices that were removed.

      :rtype: int

   .. py:method:: CombineIdentical()

      Merges identical vertices.

      :param bool ignoreNormals: If true, vertex normals will not be taken into consideration when comparing vertices.
      :param bool ignoreAdditional: If true, texture coordinates, colors, and principal curvatures \
         will not be taken into consideration when comparing vertices.

      :return: True if the mesh is changed, in which case the mesh will have fewer vertices than before.

      :rtype: bool
