- Restored BLI_pbvh_grids_update stuff;
- Marc all nodes as changes in ED_sculpt_modifiers_changed, so
draw_buffers would be keept correct.

the two files mikktspace.h and mikktspace.c. These are standalone files
which can be redistributed into any other application and regenerate the
same tangent spaces. The implementation is independent of the ordering
of faces and the vertex ordering of faces.

Used a crazyspace approach (like in edit mode), but only modifiers with
deformMatricies are allowed atm (currently shapekeys and armature modifiers only).
All the rest modifiers had an warning message that they aren't applied because
of sculpt mode. Deformation of multires is also unsupported.
With all this restictions users will always see the actual "layer" (or maybe
mesh state would be more correct word) they are sculpting on.
Internal changes:
- All modifiers could have deformMatricies callback (the same as deformMatriciesEM but
for non-edit mode usage)
- Added function to build crazyspace for sculpting (sculpt_get_deform_matrices), but it
could be generalized for usage in other painting modes (particle edit mode, i.e)
Todo:
- Implement crazyspace correction to support all kinds of deformation modifiers
- Maybe deformation of multires isn't so difficult?
- And maybe we could avoid extra bad-level-stub for ED_sculpt_modifiers_changed
without code duplicating?

- move GS() define into DNA_ID.h
- add BLI_utildefines as an automatic include with makesrna generated files.
|
|
MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.

Added a call to flush sculpting face grid changes out to ccgsubsurf's
other data (in particular, to edge grids)
Hopefully correct fix this time :)

Root cause is that some drawing modes don't work with PBVH
drawing. Worked around by adding a call to update mesh normals from
the PBVH so that sculpted changes appear correctly in those
"unsupported" modes. (They'll still draw much more slowly than solid,
but should at least appear correct now.)

reopening #22634 (sculpting/multires and wireframe display mode glitches)
* Reverting my earlier changes to subsurf edge drawing; seems to be causing more bugs than the minor bug it fixed.

object mode."
* Re-added code to draw loose edge

|
Fixed bug #22634, sculpting/multires and wireframe display mode glitches
* Changed ccgdm edge drawing to always use face griddata rather than edge data, since edge data is not updated during sculpting.

- omit render code from this warning (cmake only), until render branch is merged.
- moved -Wunused-parameter warning to apply to all C code in blender (not just ./source/blender), (cmake only).

This is a more general problem that drawing functions would skip faces when the original index could not be found, screw result for example wasnt visible in editmode too.
Fixed by adding a material set argument to DerivedMesh->drawMappedFaces(), this was already being done in some of the other drawing functions.

- fix for own mistake used madd_v3_v3fl rather then mul_v3_v3fl, r32241.

modifiers (VBOs)
Was actually a couple bugs:
* VBO bug was that hidden faces weren't being skipped correctly. Fixed that and rewrote this bit of VBO drawing code more clearly (less duplication, less unecessary state, and comments even)
* Second bug was that CCGDerivedMesh wasn't outputing ORIGINDEX data for faces. (it's not doing it for edges or verts either, but I don't know that we need it to.) At any rate, we do need this data for faces so that additional DerivedMeshes on top of subsurf know what faces in the editmesh are hidden.

Fixes various crashes and redraw problems, most noticeable new feature
is that you can now sculpt on a multires mesh with deforming modifiers
preceding it.
I've left out support for sculpting on multires with enabled modifiers
following it, in this case only the base mesh can be sculpted now. The
code changes needed to do this are just too ugly in my opinion, would
need a more torough redesign which I don't think we should try now. In
my opinion this is also not really an important case, since it's going
to be incredibly slow anyway to run a modifier on a high res mesh while
sculpting.
So, to summarize current state:
* Fastest sculpting: base mesh with no modifiers or multires with only
modifiers preceding it.
* Slower sculpting: base mesh with modifiers, depends on the speed of
the modifiers.
* Not supported: multires mesh with modifiers following it.

- link now brings up a search box so when there are 100's of groups its less annoying.
- utility functions for id-enums so only local objects can be displayed in a search list (used for group_link)
- renamed operator properties from typle to scene, group, action etc.

* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.

is displayed in the 3d view instead of only rendering, see panel in the scene

Most file changes were to make scene available in the isDisabled modifier
callback function.

Fix #20516: subsurf modiefier+pressing add for smoke sims results in crash.
Fix retopo not working correct on subsurf mesh.
Various deforming modifiers were not correctly taking into account that a
derivedmesh is not necessarily a CDDerivedMesh, made utility functions for
this now.

Also fixes:
* Weight paint subsurf drawing.
* Missing pointer endian conversion in paint brushes.
* Use of unitialized variable in screen version patch.
* Multires modifier without mdisps layer crash.
|
|
* Smooth brush works again for multires.
* Optimal Display option for multires modifier, same as subsurf.
|
|
* Multithread parts of multires and subsurf. Only loops working on
face grid data and do no memory allocation have been multithreaded,
others would be more complicated.
* Force some CCGSubsurf functions to be inlined, gives a small overall
speedup in subsurf code.
* Fix sculpting not working correct with transformed objects.
* Fix a few cases of "spikes" on lower level multires levels. There's
still cases where it happens, usually on boundary cornders. The
problem is that in such cases the limit surfaces can be very different
from the low res surface, so the tangent space is very different too..
* Fix crash deleting multires higher levels with level set to 0.
* Fix crashes that happened sometimes when adding faces in editmode.

level when rotating/panning/zooming the viewport, and only draw the full thing
at the end, to make the viewport more interactive.

* PBVH can now be created contain both from face grids or standard
meshes. The former is much quicker to build for high res meshes.
* Moved some drawing code into pbvh (mostly for the frustum test).
* Moved ray intersection code into pbvh.
* GPU buffers also can be built from either mesh or grids now.
* Updated sculpt code to work with this. The ugly part is that there
is now a macro for iterating over vertices, to handle both cases,
and some duplicated code for e.g. undo.
* Smooth brush does not work yet with grids.
|
|
* Now uses the CCG DerivedMesh also in object mode, used to be edit mode only.
* Create CD_ORIGINDEX layer on demand, to save memory.
* Removed ss_to_cdderivedmesh function, and instead create ccgdm and then
convert that to cddm, to avoid code duplication.
* Added and implement DerivedMesh interface functions to obtain face grids.
* Store edge/face flags more memory efficient.
* Export CCGDerivedMesh struct in BKE_subsurf.h

* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
