In some instances, the number of control vertices of a hair could change mid-frame.
Cycles would then be unable to calculate proper motion blur for those hairs. This adds
interpolated CVs to fill in for the missing data. While this will not necessarily result in
a fully accurate reconstruction of the guide hair, it preserves motion blur instead of disabling it.

Since we are not linking against OpenCV ourselves, that generated
linking errors later on (while building OSL e.g.).
Those 'open' libs link against way too many other libs... :/
Thanks to @intrah for initial report (T56785), and @LazyDodo for
suggested solution.

* WITH_SYSTEM_OPENJPEG is removed and is now always on, this was already
the case for macOS and Windows.
* This should not break existing Linx builds. If there is no new enough
OpenJPEG installed, CMake will no find libopenjp2 and WITH_IMAGE_OPENJPEG
will be disabled.
* install_deps.sh was updated with new package names, since distributions
put this version in a new package.

Also tried to re-enable using fedora's llvm/clang packages, would hope

Also removed last patches we used here, we shall not need any anymore!

This is in preparation of upgrading our library dependencies, some of which
need C++11. We already use C++11 in blender2.8 and for Windows and macOS, so
this just affects Linux.
On many distributions this will not require any changes, on some
install_deps.sh will need to be run again to rebuild libraries.

Two issues are fixed with this commit:
1) When we build OIIO (on unixoid build environments) and no /src/doc/oiiotool was present we had no build target for it (which led to a build error). As we don't need docs for OIIO, we disable it now.
2) We specified a var that OIIO does not recognize (was removed upstream a long time ago): ILMBASE_VERSION.

Note these are intended for platform maintainers, we do not intend to

libraries from lib/ should be used.

Based on D2578, now you can install JACK audio server and use it in
Blender build without having to specify the `--with-all` option (that
one still enables also JACK of course).

Couple of things here:
- Boost is not necesserily compiled into your /opt/lib and system-wide
version might have been used. The recent change in Alembic did not
take this into account.
- Alembic needs some extra component of Boost.
This part might be missing now for other distros than DEB.
|
|
As requested by @sergey.
|
|
It was a leftover from when Alembic with HDF5 was still officially
supported.
|
|
This provides us with a clearer API (so I don't have to use const_cast<>
in upcoming code). It also allows layering of different Alembic files,
so you can have a base file and load a separate file containing overrides.
Verbally approved by Dr. Sergey.

Alembic requires one of ALEMBIC_LIB_USES_BOOST, ALEMBIC_LIB_USES_TR1, or
C++11, and silently defaults to the latter if the former two are OFF.
Before this change, Alembic was only built without C++11 of OpenEXR
was built at the same time. This dependency was both unnecessary and
undocumented.

For now, we merely add an option that sets CXXFLAGS envvar with
'--std=c++11' option.
There is no check done to ensure compatibility with the system
libraries, mainly because:
- It is all but trivial to get this information in a generic and
reliable way.
- Currently even cutting edge distributions may still distribute some c++98
libraries.
- With recent stdlibc++, both ABIs are supported together, which means
that incompatibilities are rather unlikely.
To summarize: if your system is recent and built with gcc-5.1 or more,
you should not experience too much troubles with c++11.

All in all, this patch adds an Alembic importer, an Alembic exporter,
and a new CacheFile data block which, for now, wraps around an Alembic
archive. This data block is made available through a new modifier ("Mesh
Sequence Cache") as well as a new constraint ("Transform Cache") to
somewhat properly support respectively geometric and transformation data
streaming from alembic caches.
A more in-depth documentation is to be found on the wiki, as well as a
guide to compile alembic: https://wiki.blender.org/index.php/
User:Kevindietrich/AlembicBasicIo.
Many thanks to everyone involved in this little project, and huge shout
out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini
and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the
custom builds and compile fixes.

install_deps can fail due to conflict between gcc (referenced by base-devel) and
gcc-multilib if the latter is installed. This avoids the conflict by filtering

This commit mostly:
* removes some (very) old messages or hacks (like those for ubuntu 10.4...).
* Moves lib-specific dependencies installations to upper level
(simpler to manage, and those are small enough packages).
* Uses new dnf package manager for fedora (sigh, we now have tree different commands for fed/suse/rehl).
* fixes or enhances some options for commandline tools.
* Force anew building of oiio package, due to insane dependencies of this one in recent distro.
Part of D1933.

The script is updated for ArchLinux, since all dependencies are included in Arch's official repositories.
I've made a few changes, such as enabling OCIO and OSD without requiring locally installed lib-path, and a fix to ''get_package_version_ARCH()' so it ignores package epoch (as in the case of ffmpeg).
I intend to look at OpenVDB next.

Looks like some distro still provide llvm-3.4-devel, while no more clang-3.4.
Since clang depends on llvm of same version, check clang only should ensure
us we also have matvhing llvm... *sigh*
|
|
Until we officially support llvm3.5 or more, only allow for 3.4 llvm packages,
and build own stuff otherwise...
