BM_ELEM_INTERNAL_TAG flag wasn't ensured to be cleared.
|
|
no functional changes.
|

|
|
Saves 8 bytes per vert/edge/face.
Gives overall ~20-25% memory saving for dyntopo sculpting
and modifiers that use BMesh.
|
|
Avoids -1 all over.

code.
C++ does not allow the assignment of a void pointer to a typed pointer without
explicit casting. Since we use a generic macro in bmesh for iterators we only
ever get a void* back and cannot cast it to the target type. However, casting
the target to a void* as well solves that issue.
This tweak is #ifdef'd to be used in C++ code only.

|
|
note, this is for C++ code which expects a cast, (will be added later)
also add a macro for nop-expressions (EXPR_NOP),
when we never want an expression to be evaluated, but it should still be valid.

Store PBVH node ID in CustomData. This avoids a number of hash deletions
and checks/insertions on big hashes.

* Merely a re-implementation of core split algorithm for BMesh, taking advantage of topological data available.
* This code needs valid loop indices, so added BM_LOOP support to BM_mesh_elem_index_ensure() & co.

since enough bmesh operations can also take advantage of direct index lookups on verts/edges/faces.
developers note:
- EDBM_index_arrays_init/ensure/free -> BM_mesh_elem_table_ensure/init/free
- EDBM_vert/edge/face_at_index -> BM_vert/edge/face_at_index
- EDBM_uv_element_map_create/free -> BM_uv_element_map_create/free
- ED_uv_element_get -> BM_uv_element_get

rename DM_OMP_LIMIT to BKE_MESH_OMP_LIMIT and set to 0 when in debug mode, same for BM_OMP_LIMIT.
|
|
- add missing headers from cmake (own omission)
- quiet rna_test.c unused define warnings.
- minor style edits
- spelling corrections and ignore all uppercase words with spell checking script.
|
|
add filter function (not used yet).
|
|
also remove 'Vertex ' prefix for items in the vertex menu.
|
|
asserts instead).
temp set BM_OMP_LIMIT to zero for better testing before release.
|
|
|
|
- without python builds without warnings.
- replace MAXFLOAT -> FLT_MAX in some areas, MAXFLOAT overflows (lager then float range).
- add cmake option WITH_GCC_MUDFLAP to enable libmudflap use.

threads (which can be slow)

|
|
failed with no UV layer.
also add some safety checks for BM_ELEM_CD_GET_* macros.
|
|
unless they are needed.
configurable in 'Geometry Data' panel, will be added when running crease edges transform for example.
|
|
|
|
these cases more easily (will change before release).
|
|
BM_OMP_LIMIT may need tweaking.
|
|
- BM_mesh_elem_toolflags_ensure / bmo_flag_layer_alloc / bmo_flag_layer_free / bmo_flag_layer_clear
- BM_mesh_select_flush
- EDBM_index_arrays_init
notes:
- mostly use openmp `sections` to split operations on vert/edge/face since this is a fairly minor change.
- split tool flag pool in 3, this means we can allocate exact sizes needed and iterate on them in threads without alloc'ing.

add type checking for element buffers, there was nothing stopping python from passing any element type into an argument when in some cases only verts/edges/faces were expected.
now operator args define which types they support.
|
|
modifiers that dont use bmesh operators can skip allocating it.
|
|
being padded up anyway, added static assert to make sure it stays <=16 bytes.
|
|
to avoid many small malloc's by passing a fixes size stack variable instead.
Will give some speedup to edge-split modifier and bevel.
|
|
checking >= 0.
also remove unused bmesh decimator code.
|
|
- don't collapse boundary verts into non boundary edges (was ugly causing spikes)
- handle degenerate cases better, rather then removing double edges after collapse, check before collapsing that there won't be any degenerate faces/edges.

bmesh regression where the edge-draw flag was cleared when bmesh modifiers were used.
|
|
- memset(..., -1) is used incorrectly even though it worked: MOD_solidify.c - thanks Halley from IRC for noticing this. use fill_vn_i() instead.
- quiet warnings in editmesh_slide.c
- cleanup comments in bmesh and some other minor comment additions.

next/prev to avoid confusion.
|

BMEditMesh already stores an object pointer.
also fix for own mistake with mesh conversion refactor, shape key index was off by 1 when switching editmode.
|
|
|
|
- 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.
|
|
also correct bad assert() in previous commit.
|
|
also have doxygen ignore *.py files and fix some warnings.
