Use function style casts in C++ headers & source.
|
|
To use function style cast '(unsigned char)x' can't be replaced by
'unsigned char(x)'.
|
|
The `frame_offset` used for creating `TimeSamplings` when exporting was
being clamped, which would make subframe sampling potentially fail, or
get out of sync.

Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses

While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
use different header conventions.
doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.
See P2788 for the script that automated these edits.

Use "filepath" which is the current convention for naming full paths.
- Main use "name" which isn't obviously a file path.
- BlendFileData & FileGlobal used "filename" which is often
used for the name component of a path (without the directory).

This reverts a part of rBd3960164163c910d5031a8f076c41b39e0a5503d.
It is not a `std::shared_ptr` but a `boost::shared_ptr`.
This could probably be fixed differently, but `NOLINT` is fine now.

Replace nested `namespace blender { namespace io { namespace alembic {`
with `namespace blender::io::alembic {`.
No functional changes.

Some Windows-specific code needed adjustment after 2917df21adc8a1ce.

The Alembic exporter has been restructured by leverages the
`AbstractHierarchyIterator` introduced by the USD exporter. The produced
Alembic files have not changed much (details below), as the Alembic
writing code has simply been moved from the old exporter to the new. How
the export hierarchy is handled changed a lot, though, and also the way
in which transforms are computed. As a result, T71395 is fixed.
Differences between the old and new exporter, in terms of the produced
Alembic file:
- Duplicated objects now have a unique numerical suffix.
- Matrices are computed differently, namely by simply computing the
evaluated transform of the object relative to the evaluated transform
of its export-parent. This fixes {T71395}, but otherwise should
produce the same result as before (but with simpler code).
Compared to the old Alembic exporter, Subdivision modifiers are now
disabled in a cleaner, more efficient way (they are disabled when
exporting with the "Apply Subdivisions" option is unchecked). Previously
the exporter would move to a new frame, disable the modifier, evaluate
the object, and enable the modifier again. This is now done before
exporting starts, and modifiers are only restored when exporting ends.
Some issues with the old Alembic exporter that have NOT been fixed in
this patch:
- Exporting NURBS patches and curves (see T49114 for example).
- Exporting flattened hierarchy in combination with dupli-objects. This
seems to be broken in the old Alembic exporter as well, but nobody
reported this yet.
