- use DummyRNA_NULL_items to replace empty enums.
- replace calloc with malloc in copy_dverts since its copied over after.
- add wmGesture->userdata, so operators that use gestures have somewhere to store their own data (not used yet).
- use 2 omp sections for vert -> (edge, face) selection flushing.
- dont use face-loop iterator for cddm_from_bmesh_ex conversion to give some speedup (some modifiers use this).
- use float(*)[3] for functions that return coords.
now blenlib/BLI doesn't depend on any blenkern/BKE functions,
there are still some bad level includes but these are only to access G.background and the blender version define.
scanfill remove-doubles pass assumes ordered edges (as with curves), otherwise it can hang.
workaround this problem by skipping removing-doubles for mesh ngons, since this isnt such a common case as it is with curves and we can just not support it.
reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
This uses the weighted average of polygon centroids based on area
It work well in most cases but will be slightly wrong when polygons have
many vertices.
ideally these would be used as generated coordinates, but this is tricly because cycles calculates its own orco's and doesnt know about curve settings.
Refactored code a bit to make naming a bit more clear and added a
function to create mesh from given display list rather than from
object's displist.
Tested using plain curves (which doesn't imply using derived meshes)
and curves with constructive modifiers (which are using derived meshed).
Issue was caused by do_versions being used pdata as reference for active/render/
stencil/clone layer indices instead of fdata.
Added some utility functions used only by do_versions to be sure this indices
are set from fdata for pre-bmesh files.
The issue was caused by CDDM_tessfaces_to_faces not dealing with CD layers.
There was already function BKE_mesh_convert_mfaces_to_mpolys which converted
mfaces to mpolys with converting all CD layers. Made it a bit more general so
it might work with given arrays of faces/polys and re-used it from CDDM module.
Checked with UV and sculpt data from Blender 2.61 and it loaded nice, so
hopefully there's no regressions in loading older files.
/* Return the index of the edge vert that is not equal to 'v'. If
* neither edge vertex is equal to 'v', returns -1. */
int BKE_mesh_edge_other_vert(const struct MEdge *e, int v);
