Without this, there was no way of finding out which object, modifier
combination caused the error, making the logs not very useful
for debugging.

This removes `foreachObjectLink` from `ModifierTypeInfo`, `GpencilModifierTypeInfo`
and `ShaderFxTypeInfo`. There is no need to have both, `foreachObjectLink` and `foreachIDLink`.
There is not code that actually depends on `foreachObjectLink`.

Remove the workaround for T59395 that increases the minimal refinement to 2
to work around an OpenSubdiv bug. This bug appears to be fixed in the latest
OpenSubdiv version we are using.
Problem found by Piotr Ostrowski.

As noted in T80164, there are quite a few area of Blender where the
"Reset to Default Value" operator in button context menus doesn't work.
Modifiers are one of them, because the DNA defaults system was never
set up for them.
Additionally, this should make modifier versioning easier. Whenever a
new field is added it should be automatically initialized to the
default value.
I had to make some ordering changes in the following modifiers to work
around an error with `-Wsign-conversion` in the macros:
- Solidify Modifier
- Corrective Smooth Modifier
- Screw Modifier
Some modifiers are special cases and are skipped in this commit:
- Data Transfer Modifier
- Cloth Modifier
- Fluid Modifier
- Softbody Modifier

The convention is to keep inactive settings editable even if they are grayed
out for having no effect due to other settings.
|
|
This adds the option to either smooth the entire boundary, or to keep
corners sharp, for the Subdivision Surface and Multiresolution modifiers.
This mainly helps with compatibility with other software. The default
behavior remains to smooth the entire boundary.

This makes subdivision surfaces compatible with the old subdivision
surface modifier and other applications that do not use the limit surface.
This option is available on the Subdivision Surface modifier.

For modifier shortcuts we added a "custom_data" field to panels.
This commit uses the same system for accessing the list data that
corresponds to each panel. This way the context is only used once
and the modifier for each panel can be accessed more easily later.
This ends up being mostly a cleanup commit with a few small changes
in interface_panel.c. The large changes in the UI functions are due
to the fact that the panel custom data is now passed around as a
single pointer instead of being created again for every panel.
The list_index variable in Panel.runtime is removed as it's now
unnecessary.

These changes are smaller, made based on feedback and a pass on all
the layouts for clarity and consistency. The Multires modifier UI will
be addressed in a separate patch. Here is an overview of the changes:
Renaming Options:
- Build: "Start" -> "Start Frame"
- Curve: "From Radius" -> "Size from Radius"
- Screw: "Calc Order" -> "Calculate Order"
- Displace, Warp, Wave: "Texture Coordinates Object" -> "Object"
Move Mode Toggle to Top & Expand:
- Bevel, Boolean, Normal Edit, Subdivision
Use Columns for Tighter Spacing:
- Displace, Explode, Ocean, Particle Instance, Remesh, Shrinkwrap,
Solidify, Warp, Weighted Normal, Wave
Misc:
- Bevel: Set inactive properties for vertex bevel
- Mesh Sequence Cache: Remove box for cache file
- Skin: Don't align "Mark Loose" and "Clear Loose"
- Array: Expand relative offset subpanel by default
- Array: Move start cap, end cap to a new subpanel
- Bevel: Move width type above width

This is part of a greater blenloader decentralization effort (T76372).
For modifiers the goal is that fewer files have to be modified when
a new modifier is added.
This patch just adds the `blendWrite` and `blendRead` callbacks to
`ModifierTypeInfo` but does not change any other code yet. In the next
steps, modifier specific code will be moved from `writefile.c` and
`readfile.c` into their corresponding `MOD_*` files.

This patch implements the list panel system D7490 for modifiers.
It also moves modifier drawing to a callback in ModifierTypeInfo
in line with the extensible architecture refactoring goal T75724.
This adds a PanelRegister callback and utilities for registering
panels and subpanels. It also adds the callbacks for expansion saving
and drag and drop reordering described in D7490.
These utilities, callbacks, and other common UI elements shared
between modifiers live in MOD_ui_common.c.
Because modifier buttons are now in panels, we can make use of
subpanels for organization. The UI layouts also use the single
column layout style consistently used elsewhere in Blender.
Additionally, the mode-setting buttons are aligned and ordered
consistently with the outliner.
However, the large number of UI changes in this patch may mean
that additional polishing is required in master.
Thanks to William Reynish (@billreynish) who did a fair amount of the
layout work and to Julian Eisel (@Severin) for consistent help.

There is no user visible difference in standard builds, as there are no
volume modifiers yet. When using WITH_NEW_OBJECT_TYPES some deform only
modifiers are now available for hair and pointcloud objects.

Show control edges stores the control edges in the mesh which is
picked up by the draw manager. When applyng a subsurf (or multires) we
don't want that data present in the base mesh. Any rebuilding of the mesh
would overwrite the data anyway.
This patch introduces a new flag for applying modifiers
that can be checked to ignore storing display specific data in
the base mesh.

The issue was caused by crazy space distortion orientation happening
for subsurf modifier.
Solved by making it so subsurf only deforms the surface but keeps
matrices as-is. This is not fully mathematically correct, but is better
that the fall-back solution which was doing wrong matrices anyway.
Also, this is closer to have subsurf was handled prior to the
related changes.

Currently unused but the intention is to use this to hook up these
modifiers to a generic deformed PBVH to make it easier to sculpt or
paint on a subdivided mesh.

This is something where there is no single correct behavior,
sometimes it's needed to ignore the crease to make mesh more
smooth. But sometimes crease is to be considered after first
subdivision surface: for example, when adding extra subdivisions
for render-time displacement.
Made it an option whether modifier needs to take crease into
account or not.
Existing files should be openable in the 2.7 compatible way,
to re-create an old behavior the options is to be manually
disabled in the modifier settings.

The general idea of this change is to have a runtime data pointer
in the ModifierData, so it can be preserved through copy-on-write
updates by the dependency graph.
This is where subdivision surface modifier can store its topology
cache, so it is not getting trashed on every copy-on-write which
is happening when moving a vertex.
Similar mechanism should be used by multiresolution, dynamic paint
and some other modifiers which cache evaluated data.
This fixes T61746.
Thing to keep in mind, that there are more reports about slow
subdivision surface in the tracker, but that boils down to the
fact that those have a lot of extraordinary vertices, and hence
a lot slower to evaluated topology.
Other thing is, this speeds up oeprations which doesn't change
topology (i.e. moving vertices).

BLI should always comes first, before DNA, BKE etc. And
`BLI_utildefines.h` should come before any other BLI (since it's some
sort of system include really, among other things...).
Thisi should help to reduce the noise in patches when adding stuff
like uint64_t members to DNA structs... ;)

This commit makes it so both Subdivision Surface and Multiresolution
modifiers are caching OpenSubdiv topology. This cuts down evaluation
time quite a bit, especially for meshes which don't have many extra
ordinary verticies.
Only working for animation. Other modifications like edit mode needs
more work to make topology cache preserved by copy-on-write.

Developers should add non license comments as separate comment blocks.

This is often invalid, outdated or misleading

It's more useful to git-blame to find out who has developed the code.

Any time a modifier data has non-ID pointer, it should have own copy
function (and also take care of proper init/reset in its init callback).

This is actually a workaround for the crash in OpenSubdiv.
Topology refiner will have a crash when special conditions
are met:
- Refiner is configured to use infinitely sharp patches.
- Refinement happens for the level 1 (which we call Quality 1 on
Blender side).
- Mesh has non-quad faces.
The workaround is to force refinement to happen to level 2 (or
quality 2 on Blender side) when those conditions are met.
Later on with the next OpenSubdiv update we can remove this
workaround, since there was work done on OpenSubdiv side to
deal better with such configurations.
The modifier will now be somewhat slower, but this will be
compensated with upcoming topology cache enabled by default.
The workaround is done when initializing settings, so the
comparison of topology refiner settings is happening without
any extra workarounds there.

This commit makes it so OpenSubdiv's topology refiner is kept
in memory and reused for until topology changes. There are the
following modifications which causes topology refiner to become
invalid:
- Change in a mesh topology (for example, vertices, edges, and
faces connectivity).
- Change in UV islands (adding new islands, merging them and
so on),
- Change in UV smoothing options.
- Change in creases.
- Change in Catmull-Clark / Simple subdivisions.
The following limitations are known:
- CPU evaluator is not yet cached.
- UV islands topology is not checked.
The UV limitation is currently a stopper for making this cache
enabled by default.

This seems to be a bug in OpenSubdiv. For now simply use Catmark
subdivision scheme with infinitely sharp edges.
Later on it's either gets fixed in OpenSubdiv or we do bilinear
subdivision on our side.

This commit makes it so that subsurf/multires modifiers will respect
the WITH_OPENSUBDIV option. The WITH_OPENSUBDIV_MODIFIER option is
now gone.
For artists it mean that subsurf modifier will behave same as it is
planned for 2.80. Multires will now support sculpting, but it has some
known limitations. Those will be worked on before the final release.
If OpenSubdiv is disabled, no subsurf/multires functionality will
present.

Only affects internal API, bout could be exposed as an option for
the compatibility reasons with other software.
Is a part of some ongoing development of multires, but might or

Was only used by subsurf in the past years, it is unlikely
other modifiers will every need this any time soon.
|

Those were used for partial updates during edit mode, which will
not be possible anymore with OpenSubdiv.
Optimization for OpenSubdiv would be to re-use topology refiner
if topology does not change. But this is something to be done
for both edit and object modes, no need to have separate code
paths for those.
This commit makes OpenSubdiv to properly work in edit mode.

Was happening when using OSD for modifiers.

The main goal of this patch is to cleanup the interface of every modifier. More specifically the interface of modifiers should be DerivedMesh-free.
Internally some modifiers still use DerivedMesh. However I think it is better when the wrappers are in the modifiers so that higher level functions can use the simplified interface.
This patch removes the applyModifier_DM and applyModifierEM_DM functions. In a previous patch (rB3614d9d) the other functions that used DerivedMesh have been removed.

Attempts to substitude CCGDM with an OpenSubdiv based structure
which has less abstraction levels. The missing part in this
substitude is a face pointers which old CCGDM/multires code was
using to stitch faces (averaging boundaries).
Another curial bit missing: "reshaping" of multires CD_MDISPS
to the state of new PBVH grids.
The new code is only available when OpenSubdiv modifier is
enabled (WITH_OPENSUBDIV_MODIFIER=ON) and with debug value of
128. This is so this WIP code is not interfering with current
production machines in the studio.
