Opted to keep includes if they are used indirectly (even if removing is possible).

handling.
Most notably, BM_LOOP and BM_FACE index recompute should now be fully decoupled.

defaults in places),
add macros for initializing BMAllocTemplate's, also add assert on invalid use of bmesh_sfme()

vertex and edge),
also replace BM_face_create_quad_tri_v with BM_face_create_verts

add arguments to calculate normals when converting to bmesh:
BM_mesh_bm_from_me, DM_to_bmesh
This gives some speedup to undo (which didnt need to re-calculate vertex normals), and array modifier which doesnt need to calculate face normals at all
|
|
many modifiers were calculating normals, when those normals were ignored by the next modifier.
now flag normals as dirty and recalculate for modifiers that set use `dependsOnNormals()` callback.
Quick test on mesh with 12 modifiers (mostly build type), calculated normals 6 times, now it only runs once - so this will give some speedup too.

would be smart here).
also reserve the exact number of vert/face/edge/loops when creating a bmesh during undo.

faces since the loops are already in order, will speedup modifiers that use bmesh.
|

derivedMesh type isn't a CDDM.

unless they are needed.
configurable in 'Geometry Data' panel, will be added when running crease edges transform for example.

Issue was customdata wasnt being initialized for layers in the destination BMesh but not in the source data.
|
|
|
|
entering Edit Mode
DM_to_bmesh_ex could merge a 'dm' into an existing BMesh, in that case CD_ORIGINDEX values needed to be set to ORIGINDEX_NONE.
|
|
Thanks for Sergey for finding the bug & patching, This fix works a bit differently.
Theres no need to allocate the customdata in the first place - since its written into. So add a flag for vert/edge/face/loop creation functions so they can skip customdata creation.

- define array sizes for functions that take vectors.
- quiet some -Wshadow warnings.
- some copy/paste error in readfile.c made it set the same particle recalc flag twice.
|
|
saves running extra loop on vert/edge/face data if these values are needed after.

crash caused by own commit r50969, the fix exposed a crash in an area of code that must have never been used before.

Added missing CD_BWEIGHT layer for the modifier's DerivedMesh.
|
|
* Array modifier creates BMesh from DM; add missing CD_CREASE layer
for edge creases.
* With a modifier stack like mirror+subsurf+array, face normals were
wrong. Fix by removing CD_NORMAL layer from CCGDM output. Previously
the elements in this layer were simply copied, so they did not
reflect subdivision correctly.
* Minor style fixes in bmo_dupe.c.
Issues not yet addressed:
* Subsurf's optimal draw setting for hiding subdivision edges is not
respected by the array output.
* Slowdown issue; array modifier is much slower than in 2.62.

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.

the mouse was before a character it would select the previous, even if the cursor was closer to the space between the next 2 chars.
now find the closest point inbetween both chars.
|
|
Was caused by recent code cleanup.
|
|
|
|
- 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.
|
|
|
|
* add DM_to_bmesh_ex, DM_to_bmesh for converting a derived mesh to a BMesh (rather than a BMEditMesh)
* have a generic variable for allocsize: bm_mesh_allocsize_default, rather than copying the values about.
|
|
the input to be a CDDM.
remove conversions to CDDM for edge split and bevel (will give some
speedup).
|
|
These changes are to make the bmesh api more consistent and easier to learn, grouping similar functions which is convenient for autocomplete.
This uses similar convention to RNA.
* use face/loop/edge/vert as a prefix for functions.
* use 'elem' as a prefix too for functions that can take any type with a BMHeader.
* changed from camel case to underscore separated (like RNA).

replace 0/1 with TRUE/FALSE define.
|
|
increase is known ahead of time, will reduce reallocs and give some speedup.
|
|
- were tesselating 2 times and didnt need to.
also comment array modifier from flushing selection flags.
