This option is needed when vertex groups are used for both armature
deformation and the other purpose such as influence of mesh modifier.
Thanks to Campbell for code review!

functions.
|

to check on the active group or all groups.
notes:
- vertices with zero weights are considered the same as vertices outside of a group.
- currently these show black but this can be made a theme color.
- multi-paint overrides this option (noted in description)
|
|
|
|
- free_dverts -> BKE_defvert_array_free
- copy_dverts -> BKE_defvert_array_copy
also move the functions from BKE_mesh into BKE_deform
|
|
- replace ngon_fake_area() with generic call to BM_face_calc_area().
- add defvert_find_shared() utility function.

- added select similar direction (Y axis)
|
|
from Felix Schlitter (dalai)
made some changes to select length measurement.
|
|
add optional flag to ignore hidden elements.
also remove loop mask flag - since it wasnt used and vert/edge/face is enough.
|
|
right groups to merged vertices, only one. This made the result asymmetric,
now merged vertices will be part of both groups with half weight.
|
|
without the underscores these clogged up the namespace for autocompleation which was annoying.

This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.

use more api functions more (some vertex group editing functions were copied about), also make some functions int oapi calls.
- remove defgroup_find_index(), use BLI_findlink instead since they both work the same way.
- move static function getNearestPointOnPlane() to BLI_math api function closest_to_plane_v3()
- ED_vgroup_give_parray() added option to return an array where unselected verts are NULL (simplifies code & works for lattice when it didn't before).
- more consistant error checking of ob->actdef.
|
|
clamped when used as an array index.
|
|
- defvert_remove_index's index wasnt used anywhere, rename to defvert_remove_group
- defvert_add_to_group was local in MOD_weightvg_util.c, moved to deform.c and renamed to defvert_add_index_notest
real fix coming next...
|
|
deform.c, was local in modifier code.
|
|
|
|
|
|
- now works in vertex select + weight paint mode.
- added option not to mirror all vertex groups.
|

- the invert flag was only being used for multi-modifier, but there is no reason not to use this in normal cases as well.
- Armature modifier RNA name 'vertex_group' was incorrectly named 'vertex_group_multi_modifier' (own fault), confusion was caused by 'invert_vertex_group_multi_modifier' which was correct.
|
|
|
|
replace with defgroup_find_name() and BLI_findstring()
|
|
|
|
144 vertex groups which got quite tedious to look through.
|
|
- use mirror when the option is enabled in editmode.
- fliped group names are used when they exist.
- only the setting that is edited will be applied to the mirrored verts group.
- copy value is applied to all mirrored verts of the selection.
- normalize normalizes all vgroups and mirrors.
utility functions defvert_sync and defvert_sync_mapped, similar to defvert_copy but does not remove existing groups and optionally creates groups as needed.
defvert_sync_mapped uses a an int array for mapping the flipped values.

blender supports type changing for textures in a way that python doesnt.
add a new general function.
Example usage:
tex = bpy.data.textures.new("Foo")
tex.type = 'IMAGE'
tex = tex.recast_type()
Macro to give the number of users accounting for fake user.
ID_REAL_USERS(id)
Use this so you can remove a datablock if it has a fake users as well as apply transformations to it in the 3D view.
Move api function bpy.data.add_texture() --> bpy.data.textures.new()/remove()
|

- particle set weight operator (Shift + K) and from the menu.
- mirror vertex groups operator can also flip weight group names.
a number of utility functions for weight groups added
int *get_defgroup_flip_map(struct Object *ob);
void flip_vertexgroup_name (char *name_r, const char *name, int strip_number); // moved from modifier.c
void copy_defvert (struct MDeformVert *dvert_r, const struct MDeformVert *dvert);
void flip_defvert (struct MDeformVert *dvert, int *flip_map);

it was supposed to: needed WM_jobs_stop_all rather then WM_jobs_stop because it ends the thread rather then just setting 'stop'.
- gpl header + warning fix
|
|
Warnings still exist in the following places:
* places (exotic.c, etc.) where format strings still use 'longs' but datatype is uintptr_t (i.e. resulting from the win64 changes)
* shrinkwrap.c - a few "incompatable type" warnings
|
|
CHanged the BENCH functions to use: gettimeofday (wall time) instead of clock (cpu time)
This was to test if the openmp was working right.
|
|
*Fixed a few UI things
*Make SimpleDeform and Shrinkwrap to use vertexgroup_get_vertex_weight, a similar function
"static float vert_weight(MDeformVert *dvert, int group)" existed on modifier.c, changed
it a bit and moved into BKE_deform.h
|

blocks that were previously missed; and b) greatly increase my
ohloh stats!

It is now possible to use the geometry of Meshes and/or Lattices as the target of a constraint. All you need to do, is to create a new Vertex-Group and assign all the points that you wish to use as the target, then type that name into the VG: field for the relevant constraints.
One of the cases where this is beneficial is when you need to copy the location of a vertex. Now you don't need to make extra vertex-parents for that.
Additional Notes:
* The code takes the average of the locations of the nominated vertices, and puts that in world-space for constraint solving (and regular space-conversion stuff).
* Currently, rotation and scaling of points is not taken into account. The rotation/scaling used is from the object's matrix. Hopefully, this will only be a temporary problem (will be fixed soon)

Previous versions of Blender allowed Vertex Groups to be nameless, which
shouldn't be allowed. This caused problems with rigs from previous versions of Blender being loaded in 2.43+ versions, as the new VGroup feature for the
Armature modifier mis-identified these nameless group(s) as being the Vertex Group
to be used. As well as the checks done when renaming VGroups (from another commit), files created prior to and in 2.43 will have all such groups given default
names.
Code notes:
* I've moved the unique_vertexgroup_name function from src to blenkernel like for
constraints
* Formatting in deform.c tidied up a bit

- removed {lattice,curve}_modifier functions
- changed render code to use displist for curve rendering
instead of making its own. required adding a bevelSplitFlag
field to DispList. I also fixed the bevel face splitting
which did not work correctly in many situations.
- changed so all curve data creation happens in makeDispListCurveTypes,
includes making bevel list and filling polys
- changed render code to use displist for surface rendering
- removed Curve.orco variable, built as needed now
- removed stupid BLI_setScanFill* functions... why use a function
argument when you can use a global and two functions! Why indeed.
(this fixed crash when reloading a file with filled curves and
toggling editmode)
- bug fix, setting curve width!=1 disabled simple bevel for no
apparent reason
- cleaned up lots and lots of curve/displist code (fun example:
"if(dl->type==DL_INDEX3 || dl->type==DL_INDEX3)"). Hmmm!
- switched almost all lattice calls to go through lattice_deform_verts,
only exception left is particles
- added DBG_show_shared_render_faces function in render, just
helps to visualize which verts are shared while testing (no
user interface).
- renamed some curve bevel buttons and rewrote tooltips to be
more obvious
- made CU_FAST work without dupfontbase hack
Also by the way I wrote down some notes on how curve code
works, nothing spiffy but it is at:
http://wiki.blender.org/bin/view.pl/Blenderdev/CurveNotes

but including "virtual" modifiers (for example, an object skel-parented
to a lattice has a virtual first lattice modifier)
- removed mesh_modifier(), all functionality has been incorporated into
modifier stack (well, keys still don't exist as a modifier, but I am
not sure if they should).
- added interface option to convert a virtual modifier into a real modifier
- added option to parent to lattice object or lattice with deform
- bug fix, patch of hook indices patched all hooks (oops) not just ones
for edited mesh
NOTE: Files saved with 2.38 that include an object parented to a lattice
will not load correctly, because it will look like the object is parented
only to the object (i.e. without deform). Can be simply fixed by reparenting
or adding a lattice modifier. Older files are handled automatically.
