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.
|
|
This restores the object->data to a non-modifier evaluated state.
So this allow us to change evaluated object modifier stack directly and
get BKE_mesh_new_from_object() for the evalauted object.
|
|
Also minor style cleanup.
|
|
Convert non-empty duplicators to empties.
|
|
The issue was caused by transflag set in geometry evaluation
never copied back top original object.
Now we have a dedicated operation which does all sort copy
back to original object, so we don't have to worry about
atomic assignments or what gets set where.
Still need to move boundbox to the same function, but it
needs some careful doublechecking first.
|
|
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.
|
|
Boundbox does not depend on transform and only need geometry
component.
This change solves possible race condition accessing geometry
data and allocating/assigning pointers.
Based on disacussion in IRC with @mano-wii and @brecht.

Five years later since the original commit, is probably not so bad
timing on calling things by their clear name.

Among all the lines moved around, the general idea is quite simple.
Actually, there are two ideas implemented there.
First one, is when object itself is tagged for update, we tag its
point cache component for evaluation, which makes it so point cache
is properly reset. We do it implicitly because otherwise we'll need
to go everywhere and add explicit tag in almost all the properties.
Second thing is, we link all collider and force fields to a point
cache component using special type of link. This type of link only
allows flush if change is caused by a user update. This way reset
does not happen when change is caused due to animation, but will
properly happen when user causes indirect change to the objects
which are part of physics simulation.

Fixes edit-mesh not having a boundbox calculated for it.
|
|
Also use const qualifier for object's.

This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.
You can get more info here:
https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/
https://code.blender.org/2018/07/grease-pencil-status-update/
This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.

`BKE_pose_rebuild()` should (ideally) always trigger a rebuild of the
depsgraph, since it can add or remove posechannels.
This function now takes a Main parameter to ensure that related
depsgraphes are tagged as dirty (kept it optional, for some corner cases).
We should also probably double-check calls to that function, think in
theory it should only be called from depsgraph itself? But for now...
|
|
This unifies two almost-identical functions at the expense of having to
add one single 'flag' value at one call.
This makes copy_softbody() aware of the source/dest objects, allowing it
to make a distinction between doing depsgraph evaluation copies and real
object copies. This will be used in an upcoming commit to ensure that
the pointcache is shared between CoW copies, similar to the current
approach for rigidbody simulation.

This commit actually adds some G.main... but at much, much higher level
than the ones it removes, so should still be better ;)

Had to add some G.main to modifiers, but in 2.8 we do not need that
anymore, so it's not that bad! ;)
|
|
This is a first step to have correspondence of legacy derivedDeform
within a new formulation. Only base ground for now to support file
reading, copy-on-write remapping and such.

Time should alwaus come from depsgraph, not scene.

* Added BKE_object_get_evaluated_mesh, which can also be used outside of
Modifier context.
* BKE_modifier_get_evaluated_mesh_from_object is now a dummy wrapper
around BKE_object_get_evaluated_mesh, we do not need anything special
anymore for RENDER quality option, since this is supposed to be handled
at depsgraph level... Maybe we can get rid of it at some point, but kind
of like the idea of keeping it for now, sounds more consitent.

smoothview and the ndof versions

OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

Was caused by ec0756af6c7, once again, we can't pass view layer,
need to pass index.
The sad part is that currently we don't have quick way to look up
view layer by index. Can do similar thing as we do for bones and
bases.

This includes DNA data and any reference to the BGE code in Blender itself.
We are bumping the subversion.
Pending tasks:
* Tile/clamp code in image editor draw code.
* Viewport drawing code (so much of this will go away because of BI removal
that we can wait until then to remove this.

Pose objects may be from the active object,
or from the weight paint mesh.
Since this is such a common check move this to a function call.
|
|
The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

This adds initial multi-object editing support.
- Selected objects are used when entering edit & pose modes.
- Selection & tools work on all objects however many tools need porting
See: T54641 for remaining tasks.
Indentation will be done separately.

For the performance we convert object bases list to an array
during view layer evaluation. This makes it possible to have
very cheap index-based base lookup.
The goal of this change is to get rid of base used for function
binding, and avoid scene datablock expansion at the depsgraph
construction time.
