Add check for merging vertices into vertices that are themselves
marked for merge, was already done for array eleements but not end
caps.
Fixes bug [#31695] Array Modifier: End Cap fails if all vertices are merged
Also corrected some reversed assert arguments.
Added four new functions as shortcuts to creating GHashes that use the
standard ptr/str/int/pair hash and compare functions.
GHash *BLI_ghash_ptr_new(const char *info);
GHash *BLI_ghash_str_new(const char *info);
GHash *BLI_ghash_int_new(const char *info);
GHash *BLI_ghash_pair_new(const char *info);
Replaced almost all occurrences of BLI_ghash_new() with one of the
above functions.
- remove recently added BM_mesh_select_flush_strip(), functions purpose wasn't clear.
- add BM_mesh_elem_hflag_disable_test(), BM_mesh_elem_hflag_enable_test()
to match existing BM_mesh_elem_hflag_enable/disable_all(), these take a hflag to test before editing each element.
This replaces the need for BM_mesh_select_flush_strip().
bug was introduced in r45297, which inadvertently broke testing for multiple flags at once.
added BM_elem_flag_test_bool() and BMO_elem_flag_test_bool() to get TRUE/FALSE results rather then the flag value.
The BMO_OPSLOT_TYPEINFO array was out of date, the last two entries
were off by one. Updated with correct values and added comments to
make it easier to match up in future.
Also changed the alloc string for mapping slot's ghash to something
more descriptive than "bemsh op".
- Edge rotate would leave verts selected, this would give problems because those selections would leave edges that would try to rotate when run again. now de-select old verts on edge rotate.
- Rotating into hidden verts gave odd results, now make sure hidden state is ok.
- BMO_slot_buffer_hflag_disable / BMO_slot_buffer_hflag_enable now have flushing for the hide flag too.
- BM_mesh_normals_update was looping over all faces to find the largest one, this is no longer needed.
- calculating a face normal was looping over every faces corners twice, now only once - using the loops directly (not an iterator).
- face vert locations were being copied an array, now use directly.
- calculating the normals would copy a float vector for the next point in the face, which was never used (only current and previous used).
- was copying vectors to compute the normal, now just assign the float pointers.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
* name bmesh operator func's BMO_slot_buffer_* rather then BMO_slot_* since it wasnt obvious some only dealt with buffer, some both.
* more typechecks and asserts of BMO_ functions (I lost some time calling a map with a buffer function that failed silently).
* small speedup for extrude check - test if the edge is wire _before_ doign a hash lookup.
* add extra argument to BMO_slot_map_to_flag() to filter by vert/edge/face
* made BMO_slot_map_* / BMO_slot_buffer_* functions stricter with type checking.
* made bmesh_structure.h function names more consistant.
* remove unused code in bmesh_structure.c
* removed 'Edge Flip' operator (missing from bmesh but looked into trunk feature and dont think its worth keeping).
* tagged some BMESH_TODO's
* 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.
* change BMO_elem_flag_* defines to inline functions.
* BMO_slot_map_insert() is too big for an inline function - un-inline it.
* remove redundant casts.
