Windows would need its own version of those tests, for now just
disabling them on that platform.

with 1023 symbols crashes Blender.
Usual lack of protection against buffer overflows when manipulating
strings.
Also add some basic tests for `BLI_path_rel`.

This was caused by a side-effect of our exporting code's memory
management (Alembic considers data "written" and "final" when its C++
objects go out of scope) in combination with my change in
rB65574463fa2d. I removed an "only export UVs on the first frame" clause
because it was unclear why this restriction was there. As it turns out,
it breaks the export of the 2nd and subsequent UV maps on an animated
mesh. Effectively, on every frame the Alembic library thought we want to
create a new UV map, instead of continuing to write a new frame of data
to the existing one.
This is resolved by keeping a reference to the C++ objects for the UV
maps in memory while the exporter is running.

When the Child Of constraint is owned by a bone, before the constraint is
run the matrix is converted from world to pose space. However, setting the
inverse should also take the armature object's transform into account.

Change the seed from 0 to 1, so BLI_ghash_performance_test doesn't

Blender was not configured to exit with non-zero return code on Python errors.
A bunch of tests worked around this but not all. This removes the need for such
workarounds.

We don't bundle cffi, rather the ffi library is used for ctypes. This test is
currently passing even when there are errors, that will be fixed next.

This uses the same framework as automated modifier tests. It adds a physics

In test harness for modifier testing, now run mesh validation

The test failure in T75491 only showed up in debug builds because
`BLI_assert()` is a no-op in release builds. This is now replaced by a
proper GTests call to `ADD_FAILURE()`, ensuring that the test fails
regardless of build mode.

Use BLI_path_ prefix, more consistent names:
BLI_parent_dir -> BLI_path_parent_dir

BLI_ensure_filename -> BLI_path_filename_ensure
BLI_first_slash -> BLI_path_slash_find

BLI_add_slash -> BLI_path_slash_ensure
BLI_del_slash -> BLI_path_slash_rstrip
BLI_path_native_slash -> BLI_path_slash_native
Rename 'cleanup' to 'normalize', similar to Python's `os.path.normpath`.
BLI_cleanup_path -> BLI_path_normalize
BLI_cleanup_dir -> BLI_path_normalize_dir
BLI_cleanup_unc -> BLI_path_normalize_unc
BLI_cleanup_unc16 -> BLI_path_normalize_unc16
Clarify naming for extracting, creating numbered paths:
BLI_stringenc -> BLI_path_sequence_encode
BLI_stringdec -> BLI_path_sequence_decode

NOTE: While most of the milestone 1 goals are there, a few smaller features and
improvements are still to be done.
Big picture of this milestone: Initial, OpenXR-based virtual reality support
for users and foundation for advanced use cases.
Maniphest Task: https://developer.blender.org/T71347
The tasks contains more information about this milestone.
To be clear: This is not a feature rich VR implementation, it's focused on the
initial scene inspection use case. We intentionally focused on that, further
features like controller support are part of the next milestone.
- How to use?
Instructions on how to use this are here:
https://wiki.blender.org/wiki/User:Severin/GSoC-2019/How_to_Test
These will be updated and moved to a more official place (likely the manual) soon.
Currently Windows Mixed Reality and Oculus devices are usable. Valve/HTC
headsets don't support the OpenXR standard yet and hence, do not work with this
implementation.
---------------
This is the C-side implementation of the features added for initial VR
support as per milestone 1. A "VR Scene Inspection" Add-on will be
committed separately, to expose the VR functionality in the UI. It also
adds some further features for milestone 1, namely a landmarking system
(stored view locations in the VR space)
Main additions/features:
* Support for rendering viewports to an HMD, with good performance.
* Option to sync the VR view perspective with a fully interactive,
regular 3D View (VR-Mirror).
* Option to disable positional tracking. Keeps the current position (calculated
based on the VR eye center pose) when enabled while a VR session is running.
* Some regular viewport settings for the VR view
* RNA/Python-API to query and set VR session state information.
* WM-XR: Layer tying Ghost-XR to the Blender specific APIs/data
* wmSurface API: drawable, non-window container (manages Ghost-OpenGL and GPU
context)
* DNA/RNA for management of VR session settings
* `--debug-xr` and `--debug-xr-time` commandline options
* Utility batch & config file for using the Oculus runtime on Windows.
* Most VR data is runtime only. The exception is user settings which are saved
to files (`XrSessionSettings`).
* VR support can be disabled through the `WITH_XR_OPENXR` compiler flag.
For architecture and code documentation, see
https://wiki.blender.org/wiki/Source/Interface/XR.

A few thank you's:
* A huge shoutout to Ray Molenkamp for his help during the project - it would
have not been that successful without him!
* Sebastian Koenig and Simeon Conzendorf for testing and feedback!
* The reviewers, especially Brecht Van Lommel!
* Dalai Felinto for pushing and managing me to get this done ;)
* The OpenXR working group for providing an open standard. I think we're the
first bigger application to adopt OpenXR. Congratulations to them and
ourselves :)
This project started as a Google Summer of Code 2019 project - "Core Support of
Virtual Reality Headsets through OpenXR" (see
https://wiki.blender.org/wiki/User:Severin/GSoC-2019/).

Use proper comparison to nullptr.
It is important to use nullptr since NULL is actually an integer,
which leads to another type of warnings.

Test specs are read from strings, and there was a comma instead
of a decimal point, and then an extra decimal point in the Quad0 test.
This test has been flaky on Windows buildbot. Perhaps this is why.

Fixed memory leak that showed up after the original issue (crash) had been fixed in 93ac4709ebe8. The fix ensures that light cache bakes free up GPU smoke textures and the smoke domain list correctly.
This commit also removes the workaround (f3a33a92987f) that disabled light cache bakes for fluid objects.

This allows fast access to various arrays in the Python API.
Most notably, `image.pixels` can be accessed much more efficiently now.
**Benchmark**
Below are the results of a benchmark that compares different ways to
set/get all pixel values. I do the tests on 2048x2048 rgba images.
The benchmark tests the following dimensions:
- Byte vs. float per color channel
- Python list vs. numpy array containing floats
- `foreach_set` (new) vs. `image.pixels = ...` (old)
```
Pixel amount: 2048 * 2048 = 4.194.304
Byte buffer size: 16.8 mb
Float buffer size: 67.1 mb
Set pixel colors:
byte - new - list: 271 ms
byte - new - buffer: 29 ms
byte - old - list: 350 ms
byte - old - buffer: 2900 ms
float - new - list: 249 ms
float - new - buffer: 8 ms
float - old - list: 330 ms
float - old - buffer: 2880 ms
Get pixel colors:
byte - list: 128 ms
byte - buffer: 9 ms
float - list: 125 ms
float - buffer: 8 ms
```
**Observations**
The best set and get speed can be achieved with buffers and a float image,
at the cost of higher memory consumption. Furthermore, using buffers when
using `pixels = ...` is incredibly slow, because it is not optimized.
Optimizing this is possible, but might not be trivial (there were multiple
attempts afaik).
Float images are faster due to overhead introduced by the api for byte images.
If I profiled it correctly, a lot of time is spend in the `[0, 1] -> {0, ..., 255}`
conversion. The functions doing that conversion is `unit_float_to_uchar_clamp`.
While I have an idea on how it can be optimized, I do not know if it can be done
without changing its functionality slightly. Performance wise the best solution
would be to not do this conversion at all and accept byte input from the api
user directly, but that seems to be a more involved task as well.

Skip light cache baking until T73921 is fixed. This should be fixed properly
but being able to run the tests at all is important now.

This moves the `alembic`, `avi`, `collada`, and `usd` modules into a common
`io` directory.
This also cleans up some `#include "../../{somedir}/{somefile}.h"` by
adding `../../io/{somedir}` to `CMakeLists.txt` and then just using
`#include "{somefile}.h"`.
No functional changes.

Introduce new IDTypeInfo structure.
Each ID type will have its own, with some minimal basic common info,
and ID management callbacks.
This patch only does it for Object type, for demo/testing purpose.
Moving all existing IDs is a goal of next "cleanup Friday".
Note that BKE_idcode features should then be merged back into BKE_idtype -
but this will have to be done later, once all ID types have been properly
converted to the new system.
Another later TODO might be to try and add callbacks for file read/write,
and lib_query ID usages looper.
This is part of T73719.
Thanks to @brecht for initial idea, and reviewing the patch.

If there were merged vertices, sometimes the output faces

The array giving original vertex indices should not contain
entries for newly created vertices. Added a test to check this.

This test is authored by Himanshi Kalra (calra).
It requires a new modifers.blend in the svn tests.

The 'random' unit tests and some examples from the new boolean code
triggered asserts and crashes. This fixes those.
There is a new flag in the input that optionally disables a pass
over input to snap segment edges to other segments.

This fixes {T70269}.
Before this commit there was complicated code to try and compute the
correct parent inverse matrix for the 'Child Of' and 'Object Solver'
constraints outside the constraint evaluation. This was done mostly
correctly, but did have some issues. The Set Inverse operator now defers
this computation to be performed during constraint evaluation by just
setting a flag. If the constraint is disabled, and thus tagging it for
update in the depsgraph is not enough to trigger immediate evaluation,
evaluation is forced by temporarily enabling it.
This fix changes the way how the inverse matrix works when some of the
channels of the constraint are disabled. Before this commit, the channel
flags were used to filter both the parent and the inverse matrix. This
meant that it was impossible to make an inverse matrix that would
actually fully neutralize the effect of the constraint. Now only the
parent matrix is filtered, while inverse is applied fully. As a result,
pressing the 'Set Inverse' matrix produces the same transformation as
disabling the constraint. This is also reflected in the changed values
in the 'Child Of' unit test.
This change is not backward compatible, but it should be OK because the
old way was effectively unusable, so it is unlikely anybody relied on
it.
The change in matrix for the Object Solver constraint is due to a
different method of computing it, which caused a slightly different
floating point error that was slightly bigger than allowed by the test,
so I updated the matrix values there as well.
This patch was original written by @angavrilov and subsequently updated
by me.

The 'Clear Inverse' operator didn't properly update the constraint, so
it didn't do anything until the entire depsgraph was updated. It's now
properly tagged for update.

In the collections unit test file developers can now disable layer
collections and declutter the 3D Viewport while working in
`constraints.blend`, without influencing the actual unit tests themselves.

Currently this only tests the Child Of constraint. My aim is to cover

There are two issues solved in this commit:
- Our Windows buildbot has slightly different floating point errors than
the Linux one, which meant a larger delta was required for float
comparisons.
- The test performs an export to a temporary Alembic file and
subsequently imports it. Deleting the temporary file was impossible on
Windows because it was still in use. This is now resolved by first
loading the default blend file before deleting the Alembic file.

The Alembic importer now works with local coordinates. Previously, the
importer converted transformations from Alembic to world coordinates
before processing them further; this processing often included
re-converting to local coordinates. This change made it possible to
remove some code that assumed that a child transform was only read after
its parent transform.
Blender's Alembic code follows the Maya convention, where in the zero
orientation the camera looks forward instead of down. This extra
rotation is now handled more consistently, and now also properly handles
children of cameras. This fixes T73269.
Unit tests were added to at least ensure that the importer and exporter
are compatible with each other, and that static and animated camera
transforms are handled in the same way.
|
|
This rename is to prepare for a future addition to the unit test file.
Currently it's named "import" and I will add an export test as well. The
rename is a separate commit to easily see the difference between the
rename and the addition of another test.
No functional changes.
