These functions are almost identical, the main difference being
BLI_join_dirfile didn't trim existing slashes when joining paths
however this isn't an important difference that warrants a separate
function.

The exporters already had Preset functionality, but the importers
did not.

Requested in D16095 proposal - also USD & Alembic have import scale

We now import and apply custom normals using a similar strategy
to the STL importer. We store custom normal data for each loop
as we read each MPoly and then apply it to the mesh after
`BKE_mesh_calc_edges()` is called.
The new behavior is optional and may be disabled in the Collada import
UI. When disabled, we use the old behavior of only using normals
to determine whether or not to smooth shade an MPoly.
----
Patch as requested in {T49814}.
The Collada import UI now has an additional checkbox, similar to the glTF and FBX import UIs:
{F13428264}
Here is a test Collada file with a simple test cube with flipped custom normals:
{F13428260}
{F13428282}
And a sphere where the two halves are disconnected geometry, but has custom normals that make the halves appear to be connected:
{F13436363}
{F13436368}
I've tested it on a number of my own meshes, and the custom normals appear to be imported
correctly. I'm not too sure about how I've plumbed the option down, though, or whether this
is the most proper way to apply custom normals.

Implement import & export support for "PBR extensions" in .mtl files
(T101029, also fixes T86736).
Newly supported parameters:
- Roughness (Pr, map_Pr)
- Metallic (Pm, map_Pm)
- Sheen (Ps, map_Ps)
- Clearcoat thickness (Pc) and roughness (Pcr)
- Anisotropy (aniso) and rotation (anisor)
- Transmittance (Tf / Kt)
Exporter has an option to enable these additional PBR parameters
export; defaults to off since not all software understands that.
Exporter UI tweaked and all material-related options were put into
their own separate box.
Added/extended test files in Subversion repository for test coverage.

These changes were implemented by Sonny Campbell.
Fixed the first issue by freeing the operator customdata when the import

By mode
A couple years ago D8598 made it so that C++ operators generally
should use "default" sort mode, which remembers previously used sort
setting. Back then all the places that needed it got changed to use
this "default" one, but since then some more IO code landed, where
seemingly by accident it used "sort by file name":
- USD importer,
- Grease Pencil exporter,
- OBJ importer & exporter,
- STL importer.

Implement ideas from T96297:
- Fix "invalid axis settings" (both forward & up along the same
direction) validation: now similar to the Python based code, when
invalid axis is applied, the other axis is changed to not conflict.
- Make axis enums be expanded inside the row, similar to Collada UI.
- Move "selected only" near the top, similar to how it's in Collada,
USD, FBX and glTF export UIs.
- Move animation export options to the bottom.

ED_fileselect_ensure_default_filepath
Follow up to D15904, a bunch of places had exact same logic for
"is filepath set? if not, set some default one", so factor all that out
into a separate ED_fileselect_ensure_default_filepath function.
|
|
Most/all C++ based IO code had a pattern of doing using
RNA_struct_property_is_set to check whether a default path needs to
be set. However, it returns false for properties restored from
"previous operator settings" (property restoration code sets
IDP_FLAG_GHOST flag on them, which "is set" sees and goes
"nope, not set").
The fix here is to apply similar logic as 10 years ago in the
T32855 fix (rBdb250a4): use RNA_struct_property_is_set_ex instead.

For SVG is very convenient to be able to import several SVG in one operation. Each SVG is imported as a new Grease Pencil object.
Also, now the SVG file name is used as Object name.
Important: As all SVG imported are converted to Grease Pencil object in the same location of the 3D cursor, the SVG imported are not moved and the result may require a manual fix of location. The same is applied for depth order, the files are imported in alphabetic order according to the File list.

Removes the following macros for scene/render frame values:
- `CFRA`
- `SUBFRA`
- `SFRA`
- `EFRA`
These macros don't add much, other than saving a few characters when typing.
It's not immediately clear what they refer to, they just hide what they
actually access. Just be explicit and clear about that.
Plus these macros gave read and write access to the variables, so eyesores like
this would be done (eyesore because it looks like assigning to a constant):
```
CFRA = some_frame_nbr;

The old Python OBJ importer had a (somewhat confusingly named) "Keep
Vertex Order -> Poly Groups" option, that imported OBJ groups as
"vertex groups" on the resulting mesh. All vertices of any face were
assigned the vertex group, with a 1.0 weight.
The new C++ importer did not have this option. It was trying to do
something with vertex groups, but failing to actually achieve
anything :) -- the vertex groups were created on the wrong object
(later on overwritten by "nomain mesh to main mesh" operation);
vertex weights were set to 1.0/vertex_count, and each vertex was only
set to be in one group, even when it belongs to multiple faces from
different groups. End result was that to the user, vertex groups were
not visible/present at all (see T98874).
This patch adds the import option (named "Vertex Groups"), which is
off by default, and fixes the import code logic to actually do the
right thing. Tested on file from T98874; vertex groups are imported
just like with the Python importer.

Adds support for vertex colors to OBJ I/O.
Importer:
- Supports both "xyzrgb" and "MRGB" vertex color formats.
- Whenever vertex color is present in the file for a model, it is
imported and a Color attribute is created (per-vertex, full float
color data type). Color coming from the file is assumed to be sRGB,
and is converted to linear upon import.
Exporter:
- Option to export the vertex colors. Defaults to "off", since not
all 3rd party software supports vertex colors.
- When the option is "on", if a mesh has a color attribute layer,
the active one is exported in "xyzrgb" form. If the mesh has
per-face-corner colors, they are averaged on the vertices.
Colors are converted from linear to sRGB upon export.

This is a partial fix for T90535.
Added Material Name Collision USD import menu option, to specify
the behavior when USD materials in different namespaces have the
same name.
The Material Name Collision menu options are
- Make Unique: Import each USD material as a unique Blender material.
- Reference Existing: If a material with the same name already
exists, reference that instead of importing.
Previously, the default behavior was to always keep the existing
material. This was causing an issue in the ALab scene, where
dozens of different USD materials all have the same name,
usdpreviewsurface1, so that only one instance of these materials
would be imported.

New OBJ exporter is missing "Path Mode" setting for exporting .mtl
files. The options that used to be available were: Auto, Absolute,
Relative, Match, Strip Path, Copy. All of them are important. The new
behavior (without any UI option to control it) curiously does not match
any of the previous setting. New behavior is like "Relative, but to the
source blender file, and not the destination export file".
Most of the previous logic was only present in Python based code

Continued improvements to the new C++ based OBJ importer.
Performance: about 2x faster.
- Rungholt.obj (several meshes, 263MB file): Windows 12.7s -> 5.9s, Mac 7.7s -> 3.1s.
- Blender 3.0 splash (24k meshes, 2.4GB file): Windows 97.3s -> 53.6s, Mac 137.3s -> 80.0s.
- "Windows" is VS2022, AMD Ryzen 5950X (32 threads), "Mac" is Xcode/clang 13, M1Max (10 threads).
- Slightly reduced memory usage during import as well.
The performance gains are a combination of several things:
- Replacing `std::stof` / `std::stoi` with C++17 `from_chars`.
- Stop reading input file char-by-char using `std::getline`, and instead read in 64kb chunks, and parse from there (taking care of possibly handling lines split mid-way due to chunk boundaries).
- Removing abstractions for splitting a line by some char,
- Avoid tiny memory allocations: instead of storing a vector of polygon corners in each face, store all the corners in one big array, and per-face only store indices "where do corners start, and how many". Likewise, don't store full string names of material/group names for each face; only store indices into overall material/group names arrays.
- Stop always doing mesh validation, which is slow. Do it just like the Alembic importer does: only do validation if found some invalid faces during import, or if requested by the user via an import setting checkbox (which defaults to off).
- Stop doing "collection sync" for each object being added; instead do the collection sync right after creating all the objects.
Cleanup / Robustness:
This reworking of parser (see "removing abstractions" point above) means that all the functions that were in `parser_string_utils` file are gone, and replaced with different set of functions. However they are not OBJ specific, so as pointed out during review of the previous differential, they are now in `source/blender/io/common` library.
Added gtest coverage for said functions as well; something that was only indirectly covered by obj tests previously.
Rework of some bits of parsing made the parser actually better able to deal with invalid syntax. E.g. previously, if a face corner were a `/123` string, it would have incorrectly treated that as a vertex index (since it would get "hey that's one number" after splitting a string by a slash), instead of properly marking it as invalid syntax.
Added gtest coverage for .mtl parsing; something that was not covered by any tests at all previously.

shouldn't be used for tooltips of boolean properties. In this case
"When checked" was the redundant language that was implied by

Also change a few conjugations to the imperative and simplify

color attribute system.
This commit removes sculpt colors from experimental
status and unifies it with vertex colors. It
introduces the concept of "color attributes", which
are any attributes that represents colors. Color
attributes can be represented with byte or floating-point
numbers and can be stored in either vertices or
face corners.
Color attributes share a common namespace
(so you can no longer have a floating-point
sculpt color attribute and a byte vertex color
attribute with the same name).

The logic in the code was _completely different_ from the documentation

"export material groups" meant "append material name to the object name",
and was only ever kicking in when the "export object groups" option was
also checked. But the proper behavior (as in 3.0 exporter & the online docs),
is to emit g objectname_materialname before each usemtl line. Which is something entirely else.
