This addresses warnings from Clang-Tidy's `readability-else-after-return`

No functional changes.

Clang Tidy reported a couple of false positives. I disabled
those `NOLINTNEXTLINE`.

- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.

Reported by @sybren on IRC, thanks.
Should be safe for 2.80.

Source (i.e. other) mesh should not be modified in any case in modifier
evaluation case (this is forbidden by design and can lead to all kind of
threaded locks and crashes), and doing so even in operator case was
never a good idea either.
Now that we can specifically request needed data (poly and/or loop
normals) from evaluation code, we can finally get rid of those
computations inside data transfer/mesh remapping area.
This is hopefully the last remaining bit of this 'bad crashing code' in
datatransfer area.

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

Just use common API func to get evaluated mesh of other object in
modifiers, instead of doing our own cooking. ;)

of my attempts.
Issue was a concurrent modification of an evaluated mesh by two
other meshes using it as source for custom normals data transfer.
Note that this fixes the crash (modifiers are strictly forbidden to modify
any data besides their own!), but now will have to add a new CD type to
be able to specifically request 'computed' clnors data layer, and not
only 'encoded' one, for source mesh...

While \file doesn't need an argument, it can't have another doxy

source data layers.
Originally, when transferring all source data layers to destination
meshes, code would abort in case destination did not have all needed
layers, and creating them was not allowed.
Now, it will instead transfer data to layers that exists, merely
skipping source ones for which it cannot find a matching destination.

Move \ingroup onto same line to be more compact and

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Move all mask-related fields from Object and OperationDepsNode
to Object_Runtime and IDDepsNode. Auto-apply DEG_TAG_GEOMETRY
if the mask changes after DEG rebuild. Update DEG API and all
code that uses it.
This fixes "source mesh data is not ready" errors from Data
Transfer modifier when parameters are changed in the UI after
the recent mesh_get_eval_final fix.

It can't be used during modifier evaluation, and rna
enum code should access the evaluated objects.

That area is now officially purged from the Devil.. errr... DerivedMesh!
|
|
Not needed anymore, we only actually need to know wether it's orig mesh
or eval one in a few places...
|
|
Removing that stuff should be valid with new depsgraph/modifiers stack
evaluation system... BUT it might not be, so rather have those in
separate own well-isolated commit.
|
|
This was actually rather hairy, this code is huge and complicated, easy
to make mistakes...
Good thing is, it will allow for significant simplification and more
(name) cleanup in following commits ;)
|

The function definitions still reside in DerivedMesh.c. Once we're done
porting all the DerivedMesh use to Mesh, we'll move the still-relevant
functions to mesh_runtime.c. This move is now cumbersome due to shared
statically-declared utility functions in DerivedMesh.c
|
|
The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

2.8x branch added bContext arg in many places,
pass eval-context instead since its not simple to reason about what
what nested functions do when they can access and change almost anything.
Also use const to prevent unexpected modifications.
This fixes crash loading files with shadows,
since off-screen buffers use a NULL context for rendering.
|
|
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.

Data transfer was not checking if the required geometry existed, thus
causing a segfault when it didn't. This adds the required checks, and
reports errors if geometry is missing.
This also replaces instances of the words "polygon" and "loop" in error
messages with "face" and "corner" respectively, to be consistent with
the rest of the existing UI.

freestyle data.
Freestyle edge/face marks are (afaik) our only actual customdata bitflags... Original work
kinda assumed we had no such things. :P

There is no real elegant solution here, ideally a modifier shall never *modify*
a source DM, but that would imply much better ways to ensure required data
is available in that source DM, which we do not have currently.
So instead, let's use brute force solution for now and always create a local copy
of our source DM, that we can modify to our heart content!
|
|
The final stage of the process (copying/interpolating new dst cddata from src cddata)
was simply broken in normal case, where we need to convert from source to destination
object space.
This patch is a bit verbose, but I cannot see how to avoid it really.
To think this code is in master since over 6 months and it only gets reported now... :/

shapekey.
Title says pretty much everything, we now have BKE and RNA funcs to get vertex, poly and
loop normals of a given shapekey.
This will be used e.g. in FBX exporter (shapekeys need normal data too).

matches best the source one.
This allows to match and transfer data between two meshes with similar shape but complete arbitrary different transform.
Note that the result will be best if the meshes (more precisely, their vertices) are exact copies of each other.
Otherwise, method used can only perform an approximated best match, which means you'll likely get better
results if you 'visually' make them match in 3D space (and use 'Object Transform') instead.
