Intro
|
||||
-----
|
||||
|
||||
This API gives access the blenders internal mesh editing api, featuring geometry connectivity data and
|
||||
access to editing operations such as split, separate, collapse and dissolve.
|
||||
|
||||
The features exposed closely follow the C API,
|
||||
giving python access to the functions used by blenders own mesh editing tools.
|
||||
|
||||
For an overview of BMesh data types and how they reference each other see:
|
||||
`BMesh Design Document <http://wiki.blender.org/index.php/Dev:2.6/Source/Modeling/BMesh/Design>`_ .
|
||||
|
||||
|
||||
.. note::
|
||||
|
||||
**Disk** and **Radial** data is not exposed by the python api since this is for internal use only.
|
||||
|
||||
|
||||
.. warning::
|
||||
|
||||
This API is still in development and experimental, while we don't expect to see large changes,
|
||||
many areas are not well tested yet and so its possible changes will be made that break scripts.
|
||||
|
||||
*Campbell Barton, 13, March 2012*
|
||||
|
||||
|
||||
.. todo::
|
||||
|
||||
* add access to BMesh **walkers**
|
||||
* add access selection history (readonly access done)
|
||||
* add a way to re-tessellate an editmode bmesh.
|
||||
|
||||
|
||||
Stand-Alone Module
|
||||
^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The bmesh module is written to be standalone except for :mod:`mathutils`
|
||||
which is used for vertex locations and normals.
|
||||
|
||||
The only other exception to this are when converting mesh data to and from :class:`bpy.types.Mesh`.
|
||||
|
||||
|
||||
Mesh Access
|
||||
-----------
|
||||
|
||||
There are 2 ways to access BMesh data, you can create a new BMesh by converting a mesh from
|
||||
:class:`bpy.types.BlendData.meshes` or by accessing the current edit mode mesh.
|
||||
see: :class:`bmesh.types.BMesh.from_mesh` and :mod:`bmesh.from_edit_mesh` respectively.
|
||||
|
||||
When explicitly converting from mesh data python **owns** the data, that is to say - that the mesh only exists while
|
||||
python holds a reference to it, and the script is responsible for putting it back into a mesh data-block when the edits
|
||||
are done.
|
||||
|
||||
Note that unlike :mod:`bpy`, a BMesh does not necessarily correspond to data in the currently open blend file,
|
||||
a BMesh can be created, edited and freed without the user ever seeing or having access to it.
|
||||
Unlike edit mode, the bmesh module can use multiple BMesh instances at once.
|
||||
|
||||
Take care when dealing with multiple BMesh instances since the mesh data can use a lot of memory, while a mesh that
|
||||
python owns will be freed in when the script holds no references to it,
|
||||
its good practice to call :class:`bmesh.types.BMesh.free` which will remove all the mesh data immediately and disable
|
||||
further access.
|
||||
|
||||
|
||||
Keeping a Correct State
|
||||
-----------------------
|
||||
|
||||
When modeling in blender there are certain assumptions made about the state of the mesh.
|
||||
|
||||
* hidden geometry isn't selected.
|
||||
* when an edge is selected, its vertices's are selected too.
|
||||
* when a face is selected, its edges and vertices's are selected.
|
||||
* duplicate edges / faces don't exist.
|
||||
* faces have at least 3 vertices's.
|
||||
|
||||
To give developers flexibility these conventions are not enforced,
|
||||
however tools must leave the mesh in a valid state else other tools may behave incorrectly.
|
||||
|
||||
Any errors that arise from not following these conventions is considered a bug in the script,
|
||||
not a bug in blender.
|
||||
|
||||
|
||||
Selection / Flushing
|
||||
^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
As mentioned above, it is possible to create an invalid selection state
|
||||
(by selecting a state and then de-selecting one of its vertices's for example), mostly the best way to solve this is to
|
||||
flush the selection after performing a series of edits. this validates the selection state.

||||
