When bmesh was in a branch we had both edit_mesh and edit_btmesh,
now there is no reason to use this odd name.
|
|
|
|
More or less same code was being executed twice during ID copying.
Makes no sense to add yet another switch-by-ID-type to handle
specificaly runtime data during ID copying, we already have
BKE_xxx_copy_data() functions for that.
|
|
Using ID_LIGHT or ID_ID for "Lamp" meaning, "Light" without context
being for 'not heavy'.
That rename of data-block was not really nice on that side of things :/
Related to T43295.

We have a display flag already, use it instead.
Object.display is kept in RNA, exposed via a nested struct,
we can move other display options there.
|
|
Issue is, ob->id.us is not relevant anymore here, since several
collection might be referencing it inside of a same scene, that is still
only one usage from user perspective...
Note that for now we are just counting scenes instantiating an object,
time will say wether we need more refined/complete check (as a reminder,
most [all?] other Object usages are *not* refcounting ones).
|
|
Move \ingroup onto same line to be more compact and
make it clear the file is in the group.
|
|
|
|
That way it is obvious when we are using default ID copy behaviour, and
when we are using advanced/specialized ones.
|
|
Time to follow conventions for that one as well.
|
|
This was used in *one* place only... much better to have a dedicated
helper for that kind of things. ;)

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

This removes a bunch of animation/driver evaluations and recalc flags that
should be redundant in the new depsgraph, and were incorrectly affecting
the evaluated scene in a permanent way.
Still two cases that could be removed if the depsgraph is improved, in
BKE_object_handle_data_update and BKE_cachefile_update_frame.
For physics subframe interpolation there are also still calls to
BKE_object_where_is_calc that should ideally be removed as well, though
they are not known to cause keyframing bugs.

Some features are incompatible with multithreading and reliable evaluation
of dependencies. We are now removing them as part of a bigger cleanup to
fix bugs in keyframing and invalid animation evaluations.
* Dupliframes have been removed. This was a hack added before there were
more powerful features like the array modifier.
* Slow parent has been removed, never worked in 2.8. It was always
unreliable for use in production due to depending on whatever frame was
previously evaluated, which was not always the previous frame.
* Particle instanced objects used to have their transform evaluated at
the particle time. Now it always gets the current time transform.
* Boids can no longer do predictive avoidance of force field objects,
but still for other particles.

Matches `BASE_FROM_SET`.

- When toggling a mode that doesn't support multi editing
only do this once of the active object.
- For sculpt mode create sculpt data since this is needed
for activating other sculpt objects on reload.
|
|
Fixes T60251.
|
|
|

|
|
|
|
- Use non-rna button for adjusting dimensions.
- Make Object.dimensions RNA read-only since it never worked well.
This is mainly a UI editing feature.

Also (mostly in comments): behaviour -> behavior (we use American English).

Object visibility is now handled by the depsgraph iterator, but this API
was incomplete as it made no distinction for visibility of the object itself,
particles and generated instances.
The depsgraph iterator API now includes information about which part of the
object is visible, and this is used by Cycles to replace the old custom logic.
Cycles and EEVEE visibility should now be consistent, which unfortunately does
means some subtle compatibility breakage for both.
Fixes T58956, T58202, T59284.

This commit makes it so curve path parent solving accepts an explicit
arguments for both time and curve speed flag, making it so we don't
have to mock around with scene's frame.
One unfortunate issue still is that if the instancing object is used
for something else, we might be running into a threading conflict.
Possible solution would be to create a temp copy of an object, but
then it will be an issue of preventing drivers from modifying other
datablocks.
At least the original issue is fixed now, and things behave same as
in older Blender version. Additionally, the global variable which
was defining curve speed flag behavior is gone now!
|
|
This is a second attempt to get the crash fixed. The original fix
worked, but it was reverted by d3e0d7f0825.
Now the logic goes as:
- All pointers which we can not have shared (the ones which are
owned by the runtime) are cleared.
- The rest of runtime stays untouched.
This seems to be enough to keep particles happy.

Only back was possible.

- Clear deprecated flags for ID's:
Scene, Sequence, World, Object & Mesh.
- Clear deprecated flags for Spaces: outliner, 3D view & image.
- Remove unused `Mesh.drawflag`
- Remove unused `USER_ALLWINCODECS`, `USER_MMB_PASTE`.
- Remove `V3D_SOLID_TEX` & `V3D_ZBUF_SELECT` - used in a few areas.
- Flip `Object.empty_image_visibility_flag`
(avoids do-version on each new flag)
- Rename 'Backside' -> 'Back' in context of drawing - showing 'Back'
makes sense.

Helps separate variable names from descriptive text.
Was already used in some parts of the code,
double space and dashes were used elsewhere.
|
|
Also minor style cleanup.
|
|
Convert non-empty duplicators to empties.
|
|
Initialize to default values for meshes w/o vertices,
note that zeroing for BKE_object_boundbox_calc_from_mesh
matches old derived mesh code.

There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.
We are using both the numpad /, as well as the regular /.
Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.
The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).
|
|
|
|
Note: functions like select all are still not respecting that.
I will fix this as part of the local view commit though.

Previously each of the objects which has armature modifier will
request deformation matricies from bbones. Thing is, all those
deformations are the same and do not depend on object which is
being modified. What's even worse is that this calculation is
not cheap.
This change makes it so bbones deformation is calculated once
and stored in the armature object. After this armature modifiers
simply use it.
With a rigs we've got here dependency graph evaluation time
goes down from 0.02 sec to 0.012 sec.
Possible further optimization is to make bbone deformation
calculated at the time when bone is calculated. This will avoid
an extra threaded loop over all bones.
|
|
Currently we never return CCGDM from the modifier stack,
so the optimization was doing pretty much nothing.
Removing it completely for now, it needs to be re-done
with the new evaluated Mesh/Subdiv.
