constraints.
This avoids traversing the archive everytime object data is needed and
gives an overall consistent ~2x speedup here with files containing
between 136 and 500 Alembic objects. Also this somewhat nicely de-
duplicates code between data creation (upon import) and data streaming
(modifiers and constraints).
The only worying part is what happens when a CacheFile is deleted and/or
has its path changed. For now, we traverse the whole scene and for each
object using the CacheFile we free the pointer and NULL-ify it (see
BKE_cachefile_clean), but at some point this should be re-considered and
make use of the dependency graph.
Never call function that might recompute a DM in an RNA itemf callback (or any UI-related func in general)!
There was an XXX comment asking if this was OK - well, no, it was not. :P
Could be ported back to some 2.78 flavour should we need it.
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/

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.

This uses a bmesh-intersection, BLI_kdtree and watertight intersections to perform boolean operations.
For now keep both BMesh and Carve booleans usable at once for testing & bug reports,
however we plan to phase out Carve by next release.
(if they're on different properties).
This patch basically gets rid of (ui-related) hack where we was adding specific
'fake' enums for datatypes needing additional options.
That was done because of broken UI code - to summarize, 'align' code did not support
correctly layout mixing vertical and horizontal sub-layouts, in particular if
it was 'column-major'.
A complete rewrite of this align code has been done, so now we can use a more
sane UI code.
The user interface was ignoring the precision step size for degrees,
making all rotation inputs drag by a 100th of a degree.
Now use a 10th of a degree instead.
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
The idea of this commit is to make it so we can enable OpenSubdiv by default
for the release builds but keep it limited to the viewport only for a specific
meshes. This is a temporary solution for until all the needed features are
supported on the OpenSubdiv side.
Flag itself is done as a dedicated field in modifier DNA so we can easily
remove it in the future without ending up with some temporary flag hanging
around forever.
Have reconsidered and feel it best to try matching previous behavior
(doing "loop slides" where possible) as default. This will avoid the
need to change regression tests, among other things.
Current behavior of bevel is to 'loop slide' along unbeveled edges
when possible, but this produces uneven bevel widths sometimes,
so this option lets user choose between having the loop slide effect
or having more even bevel widths. Trying it out with default being
'no loop slide', so different from current behavior. May reverse this
choice later, depending on user reactions.
Add slider to adjust the influence of weights relative to geometry distortion.
This allows subtle influences to be applied - without drastic changes in behavior.
Nothing much to say here, basic tool to make normals point toward a target,
or to make them point 'outward' as if object was a spheroid (useful for game bushes etc.).
Also, forgot a big thank you to Campbell for the extensive review work he has done on this project!
Titles says everything, just two notes:
* We have to actually transfer plain *normals*, not 'compressed' clnors,
so had to add pre/post process to transfer to make the conversions.
* Also added interpolation and advanced copy/mixing to CD_NORMAL, for same reasons.
- Add falloff types & curves (matching warp-modifier)
- Add uniform scale option,
important when adding hooks to non-uniform scaled objects,
especially for use with lattice objects which can't avoid uneven scaling.
This uses relative transformation set when the hook is assigned,
when measuring the distances.
