D1751, remove this library since its quite a specific - only supports an older version of this codec.
Also ffmpeg has added support for recent versions of the codec.
|
|
|
|
This restores a modification that was there before.
|
|
I tried to carefully preserve all patches since the last upgrade.
Improves T47195, cloth collision detection bug.

I've been using this fix in another branch locally, so it seems to work fine.
The other #ifdef checks should be checked on too, as __MINGW32__ and __MINGW64__
do NOT seem to be defined when compiling that file

Previously several areas were calling TEST_SHARED_PTR_SUPPORT and
TEST_UNORDERED_MAP_SUPPORT which isn't that bad on it's own but
was causing some quite verbose output with same information line
printed multiple times. additionally, what's more worse, define flags
for Ceres were duplicated in main CMakeLists and Ceres's CMakeLists.
Now we've got a single place where checks for those classes are
happening and other areas are simply checking for variables set by
those check macros, keeping CMake output clean and nice.

The main purpose of such linking is to make Blender compatible with
NVidia's debuggers and profilers which are doing some LD_PRELOAD
magic to intercept some function calls. Such magic conflicts with
our CUDA wrangler magic and causes segmentation faults.
The option is disabled by default, so there's no affect on any of
artists.
In order to make Blender linked directly against CUDA library use
the WITH_CUDA_DYNLOAD CMake option (it's marked as advanced).

Those changes are to be backported to the upstream actually, for until then
it should be good enough to have it locally.
|
|
Logically it is intern library since being mainly developed by 1.5 blender guys.
|
|
Even tho it's currently only used by Libmv we might use it for something
else in the future. Plus, it's actually where it logically belongs to.
|
|
This is where the libraries belongs to actually, they are not only used by
Libmv now, but also by tests and Cycles.
|
|
The idea is to split them into two separate targets and have dedicated include
directories list for each of them in order to avoid some annoying include header
modifications in comparison with upstream.

While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

Again brings some fixes for MSVC-2015 and keeps it easier to backport
the fixes into upstream.
|
|
Brings some extra fixes for MSVC-2015
|
|
Brings support of NVRTC bindings and also makes it easier to tweak
libraries paths and use multiple alternative names for libraries.
|
|
|
|
Some values are now restored to the ones from before the upgrade today.
|
|
Those are actually sent to a pull-request, see
https://github.com/google/glog/pull/81
|
|
Main reason is to bring up new Glog which should have MSVC 2015
support.
|
|
|
|
It's quite small chance we'll be supporting suitesparse for Blender due to all
the complexity of 3rd party libraries, so removing implementation files which
are only needed when suitesparse is enabled.

It is now updated against CUDA Toolkit 7.5. Currently should be no functional
changes, just begin some ground work for the future.
|

It brings all the performance improvements, bug fixes and stability improvements
which were done in the last year of Ceres development.

Caused by use of the uninitialized shape_ variable in Resize().

The issue was caused by RedCode library printing binary string to the terminal.
|
|
The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.

This commit contains all the remained parts needed for initial integration of
OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU
backends which works in the following way:
- When SubSurf modifier is the last in the modifiers stack then GPU pipeline
of OpenSubdiv is used, making viewport performance as fast as possible.
This also requires graphscard with GLSL 1.5 support. If this requirement is
not met, then no GPU pipeline is used at all.
- If SubSurf is not a last modifier or if DerivesMesh is being evaluated for
rendering then CPU limit evaluation API from OpenSubdiv is used. This only
replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG
structures exactly the same as they used to be for ages now.
This integration is fully covered with ifdef and not enabled by default
because there are several TODOs to be solved first:
- Face varying data interpolation is not really cleanly implemented for GPU
in OpenSubdiv 3.0. It is also not implemented for limit evaluation API.
This basically means we'll have really hard time supporting UVs.
- Limit evaluation only works with adaptivly subdivided meshes so far, which
basically means all the points of CCG are pushed to the limit. This gives
different result from old code.
- There are some serious optimizations possible on the topology refiner
creation, which would speed up initial OpenSubdiv mesh creation.
- There are some hardcoded asumptions in the GPU and DerivedMesh areas which
could be generalized.
That's something where Antony and Campbell can help, making it so the code
is structured in a way which is reusable by all planned viewport projects.
- There are also some workarounds in the dependency graph to make sure OpenGL
buffers are only freed from the main thread.
Those who'll be wanting to make experiments with this code should grab dev
branch (NOT master) from
https://github.com/Nazg-Gul/OpenSubdiv/tree/dev
There are some patches applied in there which we're working on on getting
into upstream.

It gives issues with Glog compiled in release mode.
Need to revisit the directory layout here and compiler flag, because technically
libmv is now more an intern/ library and i'll actually prefer it to be covered
with strict flags as well. But it's a bit tricky because of libraries which we
don't maintain are in the libmv subfolder.

It is rather annoying attitude nowadays to use const qualifier all over the
place, including using it for multi-dimensional arrays. This isn't really
supported in GCC prior to version 5.0 because it considers such an arrays
to be a "pointer to a const pointer" which gives implicit casting errors.
It's not possible to disable this particular type of warnings treated as
errors in any GCC version prior to 5.0 as well, meaning currently usage of
-Werror globally in Blender code is not possible at all.
This commit makes it possible to use -Werror in areas which are complaint
with older GCC versions. New advanced CMake options are:
- WITH_COMPOSITOR_WERROR
- WITH_LIBMV_WERROR
- WITH_CYCLES_WERROR

Title says pretty much everything. For now, only thing available is a solver of eigen
values/vectors for self-adjoint matrices.
We can easily add more when needed.
Thanks to Sergey and Campbell for quick review.
