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.

Also, fix missing cleanup of Object.runtime when copying Object
datablocks!
|
|
|
|
This makes tagging much more generic and make the world updates more in
line with the new tagging system (Depsgraph).
|
|
|
|
|
|
We draw small numbers over the icon of multiple objects of the same type.
Also, we make all inlined elements to be non-clickabled.
For modifiers we still do it the old way. In this case it is more important
to see the order then the ammount.

This caused crashes in some cases, and should be fully handled by
the depsgraph now.
|
|
Make it more reliable and predictable way of getting pointer to
an original mesh which came from copy-on-write engine.
Related change: made it (hopefully) more clear name for flags.
|
|
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.

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.

This will be handled by the new view layer override system which will
store data elsewhere, removing the code already for easier refactoring.

- need a draw mode in workbench engine.
- reorganized render engine retrieval in 3d view. There are 2 places
where this happenes 1. 3d view draw code and 2. draw manager.
the draw manager code is not used for external engines, currently added
an exception in for cycles. will need to have a better solution in
place.
|
|
issue was the factoring of the workspace engine that was removed. the logic implied that the clay could not be rendered as clay will be a draw mode we placed it already there so it is accessible in any engine. Should eventually fix the clay engine by migrating it to the workbench engine.

Brecht authored this commit, but he gave me the honours to actually
do it. Here it goes; Blender Internal. Bye bye, you did great!
* Point density, voxel data, ocean, environment map textures were removed,
as these only worked within BI rendering. Note that the ocean modifier
and the Cycles point density shader node continue to work.
* Dynamic paint using material shading was removed, as this only worked
with BI. If we ever wanted to support this again probably it should go
through the baking API.
* GPU shader export through the Python API was removed. This only worked
for the old BI GLSL shaders, which no longer exists. Doing something
similar for Eevee would be significantly more complicated because it
uses a lot of multiplass rendering and logic outside the shader, it's
probably impractical.
* Collada material import / export code is mostly gone, as it only worked
for BI materials. We need to add Cycles / Eevee material support at some
point.
* The mesh noise operator was removed since it only worked with BI
material texture slots. A displacement modifier can be used instead.
* The delete texture paint slot operator was removed since it only worked
for BI material texture slots. Could be added back with node support.
* Not all legacy viewport features are supported in the new viewport, but
their code was removed. If we need to bring anything back we can look at
older git revisions.
* There is some legacy viewport code that I could not remove yet, and some
that I probably missed.
* Shader node execution code was left mostly intact, even though it is not
used anywhere now. We may eventually use this to replace the texture
nodes with Cycles / Eevee shader nodes.
* The Cycles Bake panel now includes settings for baking multires normal
and displacement maps. The underlying code needs to be merged properly,
and we plan to add back support for multires AO baking and add support
to Cycles baking for features like vertex color, displacement, and other
missing baking features.
* This commit removes DNA and the Python API for BI material, lamp, world
and scene settings. This breaks a lot of addons.
* There is more DNA that can be removed or renamed, where Cycles or Eevee
are reusing some old BI properties but the names are not really correct
anymore.
* Texture slots for materials, lamps and world were removed. They remain
for brushes, particles and freestyle linestyles.
* 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and
other renderers use this to find all panels to show, minus a few panels
that they have their own replacement for.

- added `object_color_type` where the user can set if the collection
determines the color, or the object will be used for the color.
Implemented it as an enum as later this can have a random color option.
- moved OB_LIGHTING_* to DNA_view3d_types and renamed it.
- Fixed some DRY in workbench_materials.c. Can remove more DRY's but
will need to discuss the responsibility of the workbench engine as it
might become part of the eevee renderer.
|
|
- added the drawtype_solid, drawtype_wireframe, drawtype_texture to
View3D
- enabled workbench panels for important render engines
- merged workbench_materials to solid_flat_mode. All draw modes will get
its own fast implementation in the workbench
|

Folders removed entirely:
* //extern/recastnavigation
* //intern/decklink
* //intern/moto
* //source/blender/editors/space_logic
* //source/blenderplayer
* //source/gameengine
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.

Cycles is no longer using this. There are still addons using it but for
correct results with the new depsgraph this API should not be used.

This caused too many problems syncing object modes
with multiple objects/windows/workspaces, see: D3130 for details.
|
|
- Read-only access can often use EvaluationContext.object_mode
- Write access to go to WorkSpace.object_mode.
- Some TODO's remain (marked as "TODO/OBMODE")
- Add-ons will need updating
(context.active_object.mode -> context.workspace.object_mode)
- There will be small/medium issues that still need resolving
this does work on a basic level though.
See D3037

Add a enum headers to DNA, to be included in other headers
so function signatures can use enums for better type safety.
Add DNA_*_enums.h matching DNA_*.types.h as needed.

General idea of the fix: skip the whole draw manager callback madness which
was used to tag object's engine specific data as dirty. Use generic recalc
flag in ObjectEngineData structure instead. This gives us the following
benefits;
- Sovles mentioned bug report.
- Avoids whole interface lookup for opened viewports for EVERY changed ID.
- Fixes missing updates when viewport is temporarily invisible.

Main idea is to make specific engine types be a subclass of generic
ObjectEngineData structure.
This required following changes:
- Have extra size argument to engine data allocation function.
Not sure whether there is less error-prone way of doing this.
- Add init() callback to engine data allocation function.
Additionally, added some extra checks to Eevee's engine data getters, so we do
not silently cast lamp data to lightprobe data.

Those are not used anymore.

Those are not used by new dependency graph and are not needed for properly
created rigs with new granular nodes.

This allows a duplicator (as known as dupli parent) to be in a visible
collection so its duplicated objects are visible, however while being
invisible for the final render.
An object that is a particle emitter is also considered a duplicator.
Many thanks for the reviewers for the extense feedback.

Currently unused, but this is where LIB_TAG_ID_RECALC* flags will go.
Also modified other DNA to make pointer property being followed by pointer.
Makes it easier to keep track of alignment and extend nested structures without
ruining anything.

Since we are ditching layers from Blender (2.8) we need a replacement to
control groups visibility. This commit introduces collections as the building
blocks for groups, allowing users to control visibility as well as overrides
for groups.
Features
========
* Groups now have collections
This way you can change the visibility of a collection inside a group, and add
overrides which are part of the group and are prioritized over other overrides.
* Outliner
Groups can inspect their collections, change visibility, and add/remove members.
To change an override of a group collection, you need to select an instance of
the group, and then you can choose "group" in the collection properties editor
to edit this group active collection instead of the view layer one.
* Dupli groups overrides
We can now have multiple instances of the same group with an original "override"
and different overrides depending on the collection the instanced object is part
of.
Technical
=========
* Layers
We use the same api for groups and scene as much as possible.

a dependent object
The idea of this flag was to prevent snapping onto an object which depends on
currently modifying ones. Using single flag makes more sense here, and also
makes it possible to replace some ob->recalc based magic with depsgraph query
to set those flags.
|
|
There were following issues:
- This was used in a similar way of DEG's ID update callback. No reason to have
yet-another-way of informing editors/engines about changes. Better to keep
regular update mechanism usable and fast for those needs.
- It wasn't granular at all, and granularity in flags is something what we
need to support anyway, even for existing ID update.
- There is no reason to have it per-object. Depsgraph operates on IDs.
- It wasn't clear when and who clears the flag, and was possible to run into
conflicts.

While getting rid of Scene->base we got the following fixes:
* Fix "Convert To" operator
* Fix "NLA allowing to selected objects that are not selectable
* Fix scene.objects (readonly, no option to link/unlink)
Note: Collada needs to use the context SceneLayer for adding objects
however I added a placeholder, so Collada maintainers can fix this
properly.

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