Also apply 2D clamping for other tools when the option is set.
|
|
Allows for editing outlines w/o pushing geometry towards/away from
the view.

This makes brush influence into a tube instead of a sphere.
It can be used along the outline of a mesh to adjust it's silhouette.
Note that all this takes advantage of changes from vertex paint,
from testing this seems useful so exposing from the brush options.
|
|
This behavior makes more sense for sculpt, less so for painting.
Restores non PBVH behavior, adding `BKE_pbvh_find_nearest_to_ray` -
similar to ray-cast except it finds the closest point on the surface.
|
|
Prepare to add code that stores distance to the ray, avoid confusion.
|
|
Merged with soc-2016-pbvh-painting, no longer needed.

Notes:
- Changes in paint_vertex.c were simple to merge, mainly related on passing
evaluation context.
- Conflicts in EditDM and drawmesh.c are solved using code from blender2.8
branch. Those areas are deprecated and not to be used in final release.
However, it's possible that some reference code from master is lost, so
keep attention when adding alpha support for vertex painting.
|
|
Also use 'const' for brush.
|
|
This makes vertex paint match image painting more closely.
- Add falloff shape option sphere/circle
where sphere uses a 3D radius around the cursor and
circle uses a 2D radius (projected), like previous releases.
- Add normal angle option so you can control the falloff.
- Add Cull option, to paint onto faces pointing away.
Disabling normals, culling and using circle falloff
allows you to paint through the mesh.
|
|
No functional changes.

- Mirrored painting and radial symmetry, like in sculpt mode.
- Volume based splash prevention,
which avoids painting vertices far away from the 3D brush location.
- Normal based splash prevention,
which avoids painting vertices with normals opposite the normal
at the 3D brush location.
- Blur mode now uses a nearest neighbor average.
- Average mode, which averages the color/weight
of the vertices within the brush
- Smudge mode, which pulls the colors/weights
along the direction of the brush
- RGB^2 color blending, which gives a more accurate
blend between two colors
- multithreading support. (PBVH leaves are painted in parallel.)
- Foreground/background color picker in vertex paint

Mainly when object origin is not at the geometry bounding box center.
Seems to be straightforward to fix, hopefully it doesn't break some obscure case
where this was a desired behavior.

When calling sculpt from Python,
setting 3D 'location' but not 2D 'mouse' stopped working in 2.78.
Now check if the operator is running non-interactively and
skip the mouse-over check.
|
|
Note that some little parts of code have been dissabled because eval_ctx
was not available there. This should be resolved once DerivedMesh is
replaced.
|
|
Support using full material shading in sculpt & paint modes mode.
Access 'Full Shading' from the display panel when in paint modes.

BKE_depsgraph.h
This removes BKE_depsgraph.h and depsgraph.c

mesh gets modified
Do a "full" update on leaving sculpt mode, so we are sure scene will be brought
to a consistent state.
Ideally we'll only do that when there are objects which depends on geometry
without re-calculating self geometry, but that's a bit tricky currently.

Part of T49042.

Temporary solution by Sergey Sharybin, it needs further investigation.
This should not be necessary, specially since this works fine in master.

- Remove 'rotate_m2', unlike 'rotate_m4' it created a new matrix
duplicating 'angle_to_mat2' - now used instead.
(better avoid matching functions having different behavior).
- Add 'axis_angle_to_mat4_single',
convenience wrapper for 'axis_angle_to_mat3_single'.
- Replace 'unit_m4(), rotate_m4()' with a single call to 'axis_angle_to_mat4_single'.

This should make it easier to sculpt in high resolutions, downside is that the new way to calculate maximum edge length is a bit less intuitive. Maximum edge length used to be calculated as blender_unit * percentage_value, now it's blender_unit / value.
Reused old DNA struct member, but had to bump subversion to ensure correct compatibility conversion. Also changed default value slightly (would have had to set to 3.333... otherwise).
Was Requested by @monio (see https://rightclickselect.com/p/sculpting/zpbbbc/dyntopo-better-scale-input-in-constant-detail-mode) and I think it's worth testing.

Auto-enabling dyntopo w/ mode switching leaked memory when undo was used.
|
|
This can be used to re-allocate bmesh data with/without tool flags.
Needed for Symmetrize since it uses bmesh operators from dyntopo.
|
|
|
|
When no triangulation runs we can skip re-calculating normals.
|
|
|
|
Saves 8 bytes per vert/edge/face.
Gives overall ~20-25% memory saving for dyntopo sculpting
and modifiers that use BMesh.
|
|
|
|
Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.
This also fixes a bug where undo would loose key-index data.
Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.
|
|
Having to change this with the slider each time isn't so convenient
and invert in this case does nothing.
|
|
|
|
Previously the grab brush could only move ourwards when normal aligned.
|
|
This is an attempt to solve the issue by doing clip test on the original
side of the stroke. Some extra testing is required.
|

Basically, the 'fake undo' restoring orig coordinates in this case cannot work with dyntopo,
since it assumes nothing was added/removed.
For now, just prevent this 'restoration' when dyntopo is used, this is no ideal solution
from user PoV - but it's better than plain ugly crash!
Complete solution seems much more involved and outside of scope of bug handling, added a TODO note:
