Was needlessly complicated code, forgot to copy a value (foam_fade), and
was utterly leaking memory!

*Sigh* One more example of why we should keep ID management handling in
as few places as possible! It's impossible to keep more than a few
places in sync regarding which ID pointer is refcounted etc.

Also generally simplify/sanitize this copy code.
|
|
This way the code is more decoupled from the way where depsgraph is stored.
|
|
Was looping three times over the source mesh's vertices to get min/max
along all three axes... Nothing critical, but still!
|
|
This way we reduce amount of time wasted in spin-lock later on when all threads
are starting to sample texture.

Root of the issue here was that two stupid modifiers could create named
vgroup CD layers (vgroup editing ones... shame on me :") ).
Fix that, and added some versionning code to also fix 'corrupted' blend
files created by those so far.

from reading baked data
Sanitize a bit how cache path is handled by fluidsim (there is much more
to be done here though :( ), and forbid empty path (we reset to default
path relative to current .blend file in case it's empty).
If people really, really want to use current OS-wise directory, they can at
least use '.' as path. ;)

More explicit, easier to read & understand.

The mirror modifier now has two fields that specify a -1 to 1 offset for
the U and V axes when mirroring their coordinates.

Please provide valid description for SurfaceDeform modifier tooltip.
Such place-holders should not pass final checks before merging in master!

This slightly changes SDef behavior, by now respecting object transforms
at bind time, thus not requiring the objects to be aligned in their
respective local spaces, but instead using world space.

Implementd fix suggested by @sergey in T50838.

Implementation of the SDef modifier, which allows meshes to be bound by
surface, thus allowing things such as cloth simulation proxies.

The title says it all actually. Use BLI task to loop over vertices
and distort their locations. Gives 2x FPS increase in a file with
just time-dependent displace modifier on my desktop.
|
|
This version will give less spin locks and now well-tested by render engines.
This should reduce amount of threading overhead when having multiple objects
with displace modifier enabled.
In the future this will also help us threading the modifier.
There are more modifiers which could benefit from this, but let's first
investigate the new behavior with one of them.

Better to have clear way to tell whether flag is parameter for
BKE_library_foreach_ID_link(), parameter for its callback function, or
return value from this callback function.

Checking only whether mverts is same as base mesh one is not enough in
all cases, some modifiers (deform ones) can only generate new mvert
data, while keeping others from original mesh.
Now checking both mvert or medge, hopefully this will be enough to catch
all problematic cases this time.
Thanks @gaia for finding that problem. :)

Custom normals need Autosmooth setting to be enabled, always!
|
|
|
|
When control object is used we need to known our own transformation as well.
|
|
Was also affecting object linking.

- Remove 'rotate_m2', unlike 'rotate_m4' it created a new matrix
duplicating 'angle_to_mat2' - now used instead.
(better avoid matching functions having different behavior).
- Add 'axis_angle_to_mat4_single',
convenience wrapper for 'axis_angle_to_mat3_single'.
- Replace 'unit_m4(), rotate_m4()' with a single call to 'axis_angle_to_mat4_single'.

They were not real issues, it's just some areas of code tried to create
relations between non-existing nodes without checking whether such
relations are really needed.
Now it should be easier to see real bugs printed.
Hopefully should be no regressions here.

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.

Since the collision modifier cannot be disabled, it causes a constant
hit on the viewport animation playback FPS. Most of this overhead can
be automatically removed in the case when the collider is static.
The updates are only skipped when the collider was stationary during
the preceding update as well, so the state is stored in a field.
Knowing that the collider is static can also be used to disable similar
BVH updates for substeps in the actual cloth simulation code.

It's a bit tricky to align vertex color data between Blender and OpenSubdiv
so for now we simply disable OpenSubdiv in the paint modes.
Safe for 2.78.
