This only adds Shift+A > Volume object and displays a list of grid names
in a specified VDB file. Branch pushed for reference if someone other than
me wants to pick up this project.

find_elem(olddata=NULL) doesn't work reliably for existence checks; it will
return NULL both when the field is found at offset 0 and when it is not
found at all.

Strip unindented comment blocks - mainly headers to avoid conflicts.

This will currently only work for the RelWithDebInfo configuration since asan
does not support the debug crt. for source line information in the reports,
you need a copy of llvm-symbolizer in the blender folder or set the
ASAN_SYMBOLIZER_PATH environment variable to point to it. Currently (as of
6.0.0) llvm-symbolizer does not ship with the binary clang/llvm distribution.

Tab after C++ comment broke parsing and didn't remove the line at all.
Was there since 2002 at least, probably confused some peeps.
This means commented out code was actually written to SDNA.

No need to print status for basic & reliable operations,
build systems can output operations they run if needed,
or debug output changed in the source if developers are debugging.
Nice for ninja, so any printed text hints at a problem to fix.

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.

Applying cflags globally can be problematic especially with extern, intern libs.
Now flags from target named will be used when defined,
allowing for developers to define flags for modules they maintain.
Convention is CMAKE_CFLAGS_${UPPERCASE_TARGET_NAME}, (CXXFLAGS for C++).
eg: CMAKE_CFLAGS_BF_BLENDER, CMAKE_CFLAGS_MAKESDNA, CMAKE_CXXFLAGS_CYCLES_KERNEL
On Linux run `make help` for full list of names, MSVC shows these in the solution.

Avoids decoding the SDNA string every undo step.
|
|
This was printed to the stdout, however the error case wasn't checked or well supported.
Also, errors decoding SDNA would sometimes call exit(1).
|
|
- Move last-hit index out of SDNA struct
(allows for access by multiple threads).
- Replace O(n^2) search with hash lookup in DNA reconstruction.
|
|
Since SDNA was allocated for each undo step,
the new address meant it was considered different and included again.
Add an option not to duplicate the DNA string when calling DNA_sdna_from_data,
as well as avoiding a redundant copy, it writes the same address each time.
|
|
Removes many hash lookups per file-save and undo-step.
|
|
Replace inline endian switching
|
|
|
|
This was causing alignment issues which were only visible on a platform
of particular bitness, so it was easy to break stuff for 32bit when
working on 64bit platform and vice versa.
|
|
|
|
924c626 broke loading on systems with different endian.
We could support reading values from SDNA, it isn't really worth the extra hassle.
Long support is still removed, just keep enum values the same.
|
|
|
|
Turns out even in files this was used, it was only for runtime members that are now ignored.
|
|
Wasn't showing error output in some cases.
Also reduce variable scope in calculate_structlen
|
|
This wasn't correct, and long was only ever used in cases we can now ignore.

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

Internal inconsistency: lastfind was being checked
on every DNA_struct_find_nr call, but never set.
Gives minor speedup reading files.

utils to API.
This patch is the root of the GHash rework, all other diff will be based on it:
Reduce average load from 3.0 to 0.75
----------------------------------
This is the big performance booster part, e.g. makes tracing a dyntopo stroke between 25% and 30% faster.
Not much to say about it, aside that it obviously increase memory footprint (about 25% - 30% too).
Add optional shrinking
----------------------------------
I.e. ghashes/gsets can now shrink their buckets array when you remove enough entries. This remains optional and OFF by default.
Add code to use masking instead of modulo
----------------------------------
Buckets indices are obtained from hashes by “reducing” the hash value into the valid bucket range. This can be done either by bit-masking, or using modulo operation.
The former is quicker, but requires real hashes, while the later is slower (average 10% impact on ghash operations) but can also be used as a 'fake' hashing on raw values, like e.g. indices.
In Blender currently not all ghash usages actually hash their keys, so we stick to modulo for now (masking is ifdef’ed out), we may however investigate the benefits of switching to masking with systematic very basic hashing later…
Add various missing API helpers
----------------------------------
I.e. a way to deep-copy a ghash/gset, and a way to (re-)reserve entries (i.e. manually grow or shrink the ghash after its creation).
Various code refactoring
----------------------------------
* Get rid of the 'hack' regarding ghash size when used as gset (it’s simpler and safer to have two structs defined here, and cast pointers as needed).
* Various re-shuffle and factorization in low-level internal code.
* Some work on hashing helpers, introducing some murmur2a-based hashing too.
Thanks a bunch to Campbell for the extensive review work. :)

This commit introduces a few ready made effects for the 3D viewport
and OpenGL rendering.
Included effects are Depth of Field, accessible from camera view
and screen space ambient occlusion. Those effects can be turned on and
tweaked from the shading panel in the 3D viewport.
Off screen rendering will use the settings of the current camera.

Configuration used to override the link flags, it better restore them
once the configuration is done.
|
|
Hopefully it'll fix "anonymous version tag cannot be combined with other version"
compilation error.
