Mesh
====
.. module:: ezdxf.entities
:noindex:
The MESH entity (`DXF Reference`_) is a 3D mesh similar to the :class:`Polyface` entity.
All vertices in :ref:`WCS` as (x, y, z) tuples
.. versionchanged:: 0.8.9
:class:`Mesh` stores vertices, edges, faces and creases as packed data.
======================== ==========================================
Subclass of :class:`ezdxf.entities.DXFGraphic`
DXF type ``'MESH'``
Factory function :meth:`ezdxf.layouts.BaseLayout.add_mesh`
Inherited DXF attributes :ref:`Common graphical DXF attributes`
Required DXF version DXF R2000 (``'AC1015'``)
======================== ==========================================
.. seealso::
:ref:`tut_mesh` and helper classes: :class:`~ezdxf.render.MeshBuilder`, :class:`~ezdxf.render.MeshVertexMerger`

MeshData
--------
.. class:: MeshData
.. attribute:: vertices
A standard Python list with (x, y, z) tuples (read/write)
.. attribute:: faces
A standard Python list with (v1, v2, v3,...) tuples (read/write)
Each face consist of a list of vertex indices (= index in :attr:`vertices`).
.. attribute:: edges
A standard Python list with (v1, v2) tuples (read/write). These list
represents the edges to which the :attr:`edge_crease_values` values
will be applied. Each edge consist of exact two vertex indices
(= index in :attr:`vertices`).
.. attribute:: edge_crease_values
A standard Python list of float values, one value for each edge. (read/write)
.. automethod:: add_face
.. automethod:: add_edge_crease
.. automethod:: optimize
