The flags were set and cleared correctly, but nothing was actually reading
them.
|
|
The flag was only used in readfile.c, and resulted in a delayed call to
BKE_ocean_add(); this call is now immediately made instead as it's not
very expensive.

this is actually adding option to add buggy behavior, but.. NPR often
expects buggy behaviors, and its one of the main targets for normal editing.
So think it's reasonable to add that option (disabled by default of
course).
Note that am not really happy with UI, but:
* Not sure where to put it, it's kind of own self-contained area option.
* Don't to make it too much visible, using this should be the exception!

The work is mainly from Lukas Toenne, with some modifications from myself.
Includes following obvious changes:
- Particle system selection is now name-based, with lookup menu.
- Lots of new options to control varieties.
Changes comparing to the Gooseberry branch:
- Default values and versioning code ensures same behavior as the
old modifier.
- Custom data layers are coming from vertex color, the modifier
does not create arbitrary layers now. The hope is to keep data
more manageable, and maybe make it easier to select in the shader
later on.
This means, values are quantized to 256 values, but it should be
enough to get varieties in practice.

We've got quite comprehensive BMesh based implementation, which is way easier
for maintenance than abandoned Carve library.
After all the time BMesh implementation was working on the same level of
limitations about manifold meshes and touching edges than Carve. Is better
to focus on maintaining one boolean implementation now.

Convention was only followed loosely,
apply to DNA where changes aren't likely to conflict.
(Skipped ModifierType for eg).
|

Useful for baking, so UV's can be moved outside the image
and not used to bake pixels (but still used for display).

Only show & use when running in debug mode.

Vertices on the axis can be optionally merged,
nice for creating objects which close at the end-points.

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

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

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.

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.

There are still issues with overlapping geometry,
however some of the issues reported are are causing problems,
or fail entirely with Carve too.

Allows to avoid generating flipped faces when using extreme normal modifications.

It also fixes another issue (crash) related to symmetric editing.
Quite involved, we (try to!) fix complete broken logic of parts of particle code, which would use poly index
as tessface one (or vice-versa). Issue most probably goes back to BMesh integration time...
This patch mostly fixes particle editing mode:
- Adding/removing particles when using generative modifiers (like subsurf) should now work.
- Adding/removing particles with a non-tessellated mesh (i.e. one having ngons) should also mostly work.
- X-axis-mirror-editing particles over ngons does not really work, not sure why currently.
- All this in both 'modes' (with or without using modifier stack for particles).
Tech side:
- Store a deformed-only DM in particle modifier data.
- Rename existing DM to make it clear it's a final one.
- Use deformed-only DM's tessface2poly mapping to 'solve' poly/tessface mismatches.
- Make (part of) mirror-editing code able to use a DM instead of raw mesh, so that we can mirror based on final DM
when editing particles using modifier stack (mandatory, since there is no way currently to find orig tessface
from an final DM tessface index).
Note that this patch is not really nice and clean (current particles are beyond hope on this side anyway),
it's more like some urgency bandage. Whole crap needs complete rewrite anyway,
BMesh's polygons make it really hard to work with current system (and looptri would not help much here).
Also, did not test everything possibly affected by those changes, so it needs some users' testing & validation too.

Binding code was re-building its own DM for the cage, now it uses given one instead.
I cannot see really any good reason not to use 'visual' modified cage for binding process,
using base mesh instead was breaking any 'advanced' binding as described in the report.
|

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.

normals, instead of vertex normals.
User suggestion/request from 'boby'.
|
|
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.

Note that the collision modifier doesn't have any use for Loop indices,
so to avoid duplicating the loop array too,
MVertTri has been added which simply stores vertex indices (runtime only).

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.

This modifier can be used to correct bad deformations,

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!

- 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.

Similar to 'Root' but without noticeable spike/pinch in the center.

This way it doesn't have to be stored as DNA runtime pointers or passed
down as a function argument. Currently there is now no property or
button to enable debugging, this will be added again later.

This helps to create some variation in a hair system, which can
otherwise become very uniform and boring. It's yet another confusing
setting in a system that should have been nodified, but only option for
now (broken windows ...)

This returns a general status (success/no-convergence/other) along with
basic statistics (min/max/average) for the error value and the number
of iterations. It allows some general estimation of the simulation
quality and detection of critical settings that could become a problem.
Better visualization and extended feedback can follow later.

This will allow us to implement moving reference frames for hair and
make "fictitious" forces optional, aiding in creating stable and
controllable hair systems.
Adding data in this place is a nasty hack, but it's too difficult to
encode as a DM data layer and the whole cloth modifier/DM intermediate
data copying for hair should be removed anyway.

as forces, velocities, contact points etc.
This uses a hash table to store debug elements (dots, lines, vectors at
this point). The hash table allows continuous display of elements that
are generated only in certain time steps, e.g. contact points, while
avoiding massive memory allocation. In any case, this system is really
a development feature, but very helpful in finding issues with the
internal solver data.
|
|
Not much to add, modifier uses same code as operator basically, only key difference
is that modifier will never create data layers itself, you have to use dedicated operator
for that.
