This is required for Cycles to report a meaningful error message when it fails to load a PTX module

Porting fix for SDL 2 audio formats from audaspace upstream.

Issue was introduced in 7bb3d9787ead with new Mantaflow files from 61280e5af3da.
|
|
Includes changes for particle skipping during advection.
|
|
structure
Issue was being caused by a particle offset which was random but the same for every particle.
|
|
Update includes new grid helper functions and some cleanups.
|
|
Do not use sort-includes in Manta source files for now when applying clang-format. Too many conflicts.
|
|
No functional changes:
- Cleanup Spelling, Line Length
- Use proper class method styling for py docs
- Fix Broken Links

Includes only a rename. The name PyInit_Main was a bit confusing as it just belongs to Manta.

|
Includes additional minmax check for Windows
|
|
Also check MSVC instead of WIN32, for setting MSVC flags.

Bullet currently generates the majority of the warnings
on windows all of them are silly. This patch disables
all warns from bullet for now.
We should revisit this if/when we update bullet

`google::LogMessageFatal::~LogMessageFatal` calls `abort`
which MSVC correctly identifies as 'not returning'
and warns about a potential memory leak.
Given this is intended behaviour and glog is not overly
concerned with shutting down the process nicely, we
can safely ignore this warning.

The solver will now automatically detect static scenes (no moving obstacles) and use a slightly faster pressure solve in those cases.

Updates include:
- std::move() cleanup in rcmatrix.h
- Enabled parallelization for fluid guiding (fairly noticeable speed improvement).
- More flexible flags setter function with control over boundary width.

This will more important when we start using OpenVDB in more modules.

- Fixed uninitialized result used in DynamicMusic::seek().
The comment to this function says false is returned if the handle

Updates include:
- A fix from Jacques that changed the loop order in the mesh creation function (the fix speeds up the function significantly due to fewer cache misses).
- Some of the grid copy helper functions are now multithreaded.
- A fix for Windows file IO. Now it possible to load files with non ASCII characters on Windows too.

Needs more consideration. This fixes compilation for now.

Updates in the files include:
- New manta files now use an platform independent gzopen function
- Adjusted argument name for vorticity

Minor adjustments for the build directory location.

This modifies the common CUDA implementation for adaptive kernel compilation slightly to support both CUBIN and PTX output (the latter which is then used in the OptiX device). It also fixes adaptive kernel compilation on Windows.

MSVC has a conformance mode (/permissive-) where the C++ standard is more strictly
enforced. This mode is available on MSVC 15.5+ [1]
This patch enables this mode on compilers that support it and cleans up the few violations it threw up in the process.
- Mantaflow was using M_PI without requesting them using the _USE_MATH_DEFINES define to opt in to non default behaviour.
- Collada did not include the right header for std::cerr, this seemingly was fixed for other platforms already but put inside a platform guard.
- Ghost had some scoping issues regarding uninitialized variables and goto behaviour
Second landing of this patch, earlier commit was reverted due to some compiler configurations having slipped though testing

Glew.obj is one of the more expensive targets we have to build clocking in
at 34.907 seconds.
The root cause [1] is the msvc inliner is not super thrilled with the
glewIsSupported supported function, this patch changes the buildflags
of extern_glew to optimize for size rather than speed.
Given glew is only in play at initalization time there will be no
performance impact.

Root of the problem was that Manta's Python API was converting to and from Latin1 instead of UTF8.

This is a more correct fix to the issue Brecht was fixing in D6600.
While the fix in that patch worked fine for linking it broke ASAN
runtime under some circumstances.
For example, `make full debug developer` would compile, but trying
to start blender will cause assert failure in ASAN (related on check
that ASAN is not running already).
Top-level idea: leave it to CMake to keep track of dependency graph.
The root of the issue comes to the fact that target like "blender" is
configured to use a lot of static libraries coming from Blender sources
and to use external static libraries. There is nothing which ensures
order between blender's and external libraries. Only order of blender
libraries is guaranteed.
It was possible that due to a cycle or other circumstances some of
blender libraries would have been passed to linker after libraries
it uses, causing linker errors.
For example, this order will likely fail:
libbf_blenfont.a libfreetype6.a libbf_blenfont.a
This change makes it so blender libraries are explicitly provided
their dependencies to an external libraries, which allows CMake to
ensure they are always linked against them.
General rule here: if bf_foo depends on an external library it is
to be provided to LIBS for bf_foo.
For example, if bf_blenkernel depends on opensubdiv then LIBS in
blenkernel's CMakeLists.txt is to include OPENSUBDIB_LIBRARIES.
The change is made based on searching for used include folders
such as OPENSUBDIV_INCLUDE_DIRS and adding corresponding libraries
to LIBS ion that CMakeLists.txt. Transitive dependencies are not
simplified by this approach, but I am not aware of any downside of
this: CMake should be smart enough to simplify them on its side.
And even if not, this shouldn't affect linking time.
Benefit of not relying on transitive dependencies is that build
system is more robust towards future changes. For example, if
bf_intern_opensubiv is no longer depends on OPENSUBDIV_LIBRARIES
and all such code is moved to bf_blenkernel this will not break
linking.
The not-so-trivial part is change to blender_add_lib (and its
version in Cycles). The complexity is caused by libraries being
provided as a single list argument which doesn't allow to use
different release and debug libraries on Windows. The idea is:
- Have every library prefixed as "optimized" or "debug" if
separation is needed (non-prefixed libraries will be considered
"generic").
- Loop through libraries passed to function and do simple parsing
which will look for "optimized" and "debug" words and specify
following library to corresponding category.
This isn't something particularly great. Alternative would be to
use target_link_libraries() directly, which sounds like more code
but which is more explicit and allows to have more flexibility
and control comparing to wrapper approach.
Tested the following configurations on Linux, macOS and Windows:
- make full debug developer
- make full release developer
- make lite debug developer
- make lite release developer
NOTE: Linux libraries needs to be compiled with D6641 applied,
otherwise, depending on configuration, it's possible to run into
duplicated zlib symbols error.

Porting bug fix from audaspace upstream.

Due to some floating point errors the last frame of a VSE audio strip can
cause integer overflow and crash Blender. This overflow was caused by a
cast from `int64_t` to `int` without prior check. The crash is fixed by
keeping the variable as `int64_t` for as long as possible.
