Alembic's "inherits transform" flag wasn't taken into account when
constructing the parent object relations.
|
|
|
|
|
|
Implemented workaround for use with the legacy depsgraph.
|
|
It tried to assert that
addons/io_blend_utils/blender_bam-unpacked.whl/__init__.py was loaded when
the io_blend_utils module was imported. However, this happens only on
demand, and not directly when importing the add-on.
|
|
This is more efficient, and this use case is exactly what the else clause
is for.
|
|
|
|
Noisy change, but safe, and better do it sooner than later if we are to
rework copying code. Also, previous commit shows this *is* useful to
catch some mistakes.

Currently only find-nearest, ray-casting needs to be added.
|
|
|
|
|
|
It's now less confusing (for example, using nr_of_samples directly,
instead of using 1 / 1 / nr_of_samples). Might also have fixed a bug.
Also added unittests.
|

Houdini writes vertex data in a different format than Blender does; Houdini
uses "face-varying scope", which means that the vertex colours are indexed
by an ever-increasing number over all vertices of all faces instead of the
vertex index.
I've also merged the read_custom_data_mcols() and read_mcols() functions,
because the latter was only called from the former, and the changes in this
commit would add yet more function parameters to pass.

Also added a unit test for exporting & importing very long names.

By mistake, the code relied on ALEMBIC_ROOT_DIR being defined by the user
running the tests. Now CMake macros are used to correctly find the Alembic
root directory.
|
|
Similar to previous commit for Gflags.
|
|
This allows, for example, the path of an Alembic file to be changed from
absolute to relative, without having to reconstruct all object paths.
|
|
It is disabled by default, so should not affect existing configurations.
Main benefits of this goes as:
- Linux distros can use that to avoid libraries duplication and link
blender package against gflags package from the system.
- It it easier to test whether Blender works with updated version of
Gflags prior to re-bundling the library.
|
|
When the Alembic import is finished, all imported objects are selected.
|
|
It only tests the presence of the objects and their parent/child pointers.
Matrix and animated properties should be done in a later test.

The ABC_export and ABC_import functions both take a as_background_job
parameter, and return a boolean.
When as_background_job=true, returns false immediately after scheduling
a background job. This was the old behaviour of this function, which makes
it very hard for scripts to do something with the data after the import
or export completes.
When as_background_job=false, performs the export synchronously, and
returns true when the export was ok, and false if there were any errors.
This allows further processing.
The Scene.alembic_export() function is deprecated, and will be removed from
Blender 2.8 in favour of calling the bpy.ops.wm.alembic_export() operator.
As such, it has been hard-coded to the old background job behaviour.
|
|
The export is still slower than needed, as the particle systems themselves
aren't disabled during the export. It's only the writing to the Alembic
file that's skipped.

Curve resolution isn't natively supported by Alembic, hence it is stored
in a user property "blender:resolution". I've looked at a Maya curves
example file, but that also didn't contain any information about curve
resolution.

This allows specifying test names on the CLI, in order to run only one
of the tests.
|
|
The order number written to Alembic is the same as we use in memory, so
the +1 wasn't needed, at least according to the reference Maya exporter
maya/AbcExport/MayaNurbsCurveWriter.cpp, function
MayaNurbsCurveWriter::write(), in the Alembic source code.
Furthermore, when writing an array of nurb orders, the curve type should
be set to kVariableOrder, otherwise the importer will ignore it.

This test checks that a set of cubes are exported with the correct
transform, both with flatten=True and flatten=False.
This commit also adds an easy to use superclass for upcoming Alembic
unit tests.

The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

Support Python's buffer protocol for ID-properties.
|

SOlves the test false-positively failing in 32 bit environment.

I've moved EXPECT_M3_NEAR from abc_matrix_test.cc to testing.h, as that's
a more suitable location.
|
|
and more:
Also replaced the bool param "to_yup" with "AbcAxisSwapMode mode", so that
it's more explicit that axes are swapped.
Also added unittests for create_swapped_rotation_matrix.

No need for redundant ID's and correct arg order
|

There weren't any convenient ways to join multiple paths in C
that accounted for corner cases.
|

Utility to get a file/dir in the path by index,
supporting negative indices to start from the end of the path.
Without this it wasn't straightforward to get
the a files parent directory name from a filepath.
