also remove large, duplicate comments from sunsky.h

* C: BM_vert_separate(...)
* py: bmesh.utils.vert_separate(vert, edges)
This splits off regions around the vertex, splitting on connected edges passed in a sequence.
also made minor changes
- rename python api functions _rip to _separate
- fixed bmesh iterator being iterable its self (some parts of python expect this)
- fix memory leak in bmesh python api.

when rotating multiple edges.
Now create the rotate edge in advance and copy its customdata (before joining the faces).
This commit also fixes an annoyance where tryangulating faces could create duplicate edges.

On a user level, edge rotate now works better with multiple edges selected, it wont make zero area faces or rotate edges into existing ones.
With a single edge selected - rotate is less strict and will allow ugly resulting faces but still checks on duplicate edges.
API:
* BM_edge_rotate now takes a flag, to optionally...
** check for existing edge
** splice edge (rotate and merge)
** check for degenerate resulting faces (overlapping geometry, zero area)
** beauty - only rotate to a better fit.
... this allows it to still be used as a low level API function since all checks can be skipped.
* BM_edge_rotate() now works a bit different, it find the new edge rotation before joining the faces - exposed by BM_edge_rotate_calc().
* Added api call bmesh_radial_faceloop_find_vert() - Radial Find a Vertex Loop in Face

'bpy' module.
we cant ensure buildinfo to have utf8 encoding so access it as bytes via python - a different workaround then this patch made.
also use C style string formatting for sys_info.py
|
|
and had bad string formatting in exception.
|
|
* add BLI_rfindlink for reverse index lookup (used so bm.select_history[-1] doesn't have to loop the entire list twice).
* add bm.select_history.active so you can get the last selected item or None without having to check seq length.

if blender freed the BMesh before python was finished (on exit editmode for eg), python would attempt to access the bmesh to clear python pointers in it.
|

added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count

Thanks to Campbell for fix, adding an & to an arg.
Also needed to negate the sense of a later test.

On a place, Ctrl+T, Fkey would create a quad overlapping the 2 Tris.
Now this case is checked for in a general way - if the bounds of the face are already filled in with faces (that _only_ use these edges-verts), then dont create the face.
This is an option for the 'edgenet_fill' operator, since creating the face isnt incorrect, just not-what-you-want mostly.
added functions
* BM_edge_share_vert - returns shared vert between 2 edges.
* BM_face_exists_multi, BM_face_exists_multi_edge - check if existing faces fill the edge bounds.
* also add BM_ELEM_INTERNAL_TAG so low level functions can tag without conflicting with higher level functions that also rely on tagging elements.
|
|
* bmesh pu api __repr__ functions for mesh data.
* correct py hash defines.

BMVert.copy_from_vert_interp(vert_pair, fac)
|

already did this).
|
|
* BMLoop attributes link_loop_next/prev
* BMVert.copy_from_face_interp
|
|
* better type safety for BM_elem_flag_* and BM_elem_index_* functions.
* add BMElem type to be used where BMFace/Edge/Vert/Loop can be interchanged.
* fix bug in select manifold, found when making functions more strict.
|
|
spelling 'impliment' -> 'implement'
|
|
|
|
* BMFace.copy_from_face_interp(face)
* BMLoop.copy_from_face_interp(face, vert=True, multires=True)
These are important for rebuilding geometry from existing faces without loosing UV's, vcols etc.
|
|
also fix py api: bmesh.utils.face_split(face, v1, v2)
|

bm.verts.get(verts) / bm.faces.get(verts)

* remove 'select' and 'hide' from BMLoop
* remove BMesh.update
* add BMesh.normal_update(skip_hidden=False)
* add BMElemSet.index_update(), eg: bm.verts.index_update()
bmesh api
* BM_mesh_normals_update() now takes skip_hidden as an argument
(previously this was default behavior), however this isnt good when
using BMesh modifiers, where you want all normals to be recalculated.
* add bm_iter_itype_htype_map[], to get the iter type from a BMesh
iterator.

all elements could free them for eg.
|
|
bmesh.utils.face_join(faces)
added a utility function for converting a list of python BMesh elements into a C array.
use for this face_join as well as BMesh.faces.new()
|
|
also improved docstrings.
