The term `looptri` was used ambiguously for both single & arrays.
The term `tri` was also used, causing `tri->tri`.
Use terms:
- `looptris` for an array or when dealing with multiple items.
- `looptri` is used when dealing with a single item.
- `lt` for a single MLoopTri variables & arguments.
This was already a convention but not followed closely.
In the context of meshes `totface` reads as if its the number of faces
in the mesh. This was infact the number of looptris however as this
is converted into a "bodyface" array, use that as the prefix.
Link/append code sets the scene pointer to `null` when the active
scene is a linked one, to avoid attempt to instantiate linked data
(objects or collections) into a linked scene, which is forbidden.
However, code was still calling some functions expecting a valid scene
pointer, leading to crash.
It is unclear when exactly this issue was introduced code wise. From a
user perspective, it seems to have been revealed between 3.6 and 4.0
release (bisect points at 00a36cbf24, which does not seem to be
directly related...).
In any case, the fix is trivial and safe, so should we do another 4.0
bugfix release, this commit should be backported.
These shouldn't be called in hot loops at all, and mostly aren't
anymore anyway. Definining them outside of a header allows removing
the `BKE_customdata.hh` include from `BKE_mesh.hh`.
Doing this in preparation for also supporting volume
grids in the same type (#115270).
At some point we could also actually use an `std::variant` in this
type, but that would change behavior without futher changes.
The previous behavior, fairly rough, was simply considering all
Collections and IDs found as part of the root's hierarchy as to be
overridden.
The new behavior is based on a specific tag added to some ID usages.
Currently, these are only the links from a Collection to its Objects
and children Collections, and the link from an Object to its parent.
The goal of this huge reduction of the 'automatically overridden' set of
data in a hierarchy is to avoid creating liboverrides for 'utils' data,
e.g. a collection used as source of data by a GeometryNode generating
some parametric geometry (Blender Studio use-case: some form of LOD
handling).
In general, it means that only Collections and objects part of the
collection hierarchy of the root collection are now overridden.
This should not change in the typical recommended use-case so far (where
there is a clear root collection to the whole overridden hierarchy, and
it contains all related collections and objects).
But this should allow much less overhead (and viewport pollution, due to
the current principle that local (and therefore liboverridden) objects
have to be instanciated in a Scene) for more complex setups.
Note that the initial idea/change is fairly simple and easy to
implement, but it creates some additional complexity in the partial
resync code, since now some linked data may not be detected as needing
a liboverride anymore when processing a sub-hierarchy, while it would
require it when processing the whole hierarchy.
This required adding some more processing to the util functions which
define which ID should be overridden. It essentially creates a
'reference set' of all reference IDs that should be overridden when
the whole hierarchy is considered, and use this as additional input to
decide which ID to override when processing a sub-hierarchy for the
partial resync.

This patches refactors the compositor File Output mechanism and
implements the file output node for the Realtime Compositor. The
refactor was done for the following reasons:
1. The existing file output mechanism relied on a global EXR image
resource where the result of each compositor execution for each
view was accumulated and stored in the global resource, until the
last view is executed, when the EXR is finally saved. Aside from
relying on global resources, this can cause effective memory leaks
since the compositor can be interrupted before the EXR is written and
closed.
2. We need common code to share between all compositors since we now
have multiple compositor implementations.
3. We needed to take the opportunity to fix some of the issues with the
existing implementation, like lossy compression of data passes,
and inability to save single values passes.
The refactor first introduced a new structure called the Compositor
Render Context. This context stores compositor information related to
the render pipeline and is persistent across all compositor executions
of all views. Its extended lifetime relative to a single compositor
execution lends itself well to store data that is accumulated across
views. The context currently has a map of File Output objects. Those
objects wrap a Render Result structure and can be used to construct
multi-view images which can then be saved after all views are executed
using the existing BKE_image_render_write function.
Minor adjustments were made to the BKE and RE modules to allow saving
using the BKE_image_render_write function. Namely, the function now
allows the use of a source image format for saving as well as the
ability to not save the render result as a render by introducing two new
default arguments. Further, for multi-layer EXR saving, the existent of
a single unnamed render layer will omit the layer name from the EXR
channel full name, and only the pass, view, and channel ID will remain.
Finally, the Render Result to Image Buffer conversion now take he number
of channels into account, instead of always assuming color channels.
The patch implements the File Output node in the Realtime Compositor
using the aforementioned mechanisms, replaces the implementation of the
CPU compositor using the same Realtime Compositor implementation, and
setup the necessary logic in the render pipeline code.
Pull Request: https://projects.blender.org/blender/blender/pulls/113982
The Realtime compositor currently relies on the GPU cache in image IDs.
That cache only supports single layer images, so multi-layer images will
be acquired without a cache, introducing significant IO bottlenecks for
the GPU compositor.
This patch ignores the image GPU cache and stores the images in the
static cache manager of the compositor. Draw data was introduced to the
image ID for proper cache invalidation, like other IDs such as masks.
The downside is that the cache will no longer be shared between EEVEE
and the compositor. But realistically, images are not typically shared
between materials and compositors.
This is just a temporary solution until we have proper GPU storage
support for image buffers.

This gives better asserts in debug builds through use of Span, more
safety when name convention attributes happen to have different types
or domains, and simpler code in some cases. But the main reasoning is to
avoid relying on the specifics of CustomData more to allow us to replace
it in the future.
This adds a new "Active Camera" input geometry node, per #105761.
The node outputs the the scene's current active camera. It is available
from Input > Scene > Active Camera in the geometry nodes Add menu.
Typical usage would be to connect this node to an Object Info node to
obtain its transform. This works as expected when the camera's
transform is animated, and also when there are markers on the timeline
that change the active camera.
In order to support the aforementioned changes in the active camera,
this implementation adds depsgraph relations for all cameras referenced
by timeline markers. This eliminates the complexity of updating the
depsgraph whenever the scene switches to a different active camera,
but of course it comes at the cost of including more objects than
strictly necessary in the depsgraph for scenes that switch cameras.
Dynamically updating the depsgraph upon camera changes could be a
future improvement if there proves to be sufficient need for it.

The debug assert condition was inverted.
It is expected that we do not find a `FileHandlerType` with the given
`idname` during add. Like Operators being added twice from c code, this
will now assert if one is actually found. Python duplicates are handled
through `register_class` already.

All the relevant code is C++ now, so we don't need to complicate things
with the trip through C anymore. We will still need some wrappers, since
opensubdiv is an optional dependency though. The goal is to make it
simpler to remove the unnecessary/costly abstraction levels between
Blender mesh data and the opensubdiv code.

Fixes#115776
Create a minimal structure that contains the instructions necessary to
copy from one custom data format to another. This structure is similar
to the one used in dfacaf4f40. It should have been used in
9175d9b7c2, which instead introduced quadratic performance
relative to the number of layers when copying every element.
In this commit, copying the entire mesh and adding new custom data
are explicitly changed to use the new map to speed up copying many
elements at a time.
The non-map attribute copy functions are also changed to check for when
the source and result BMeshes are the same. In that case it's much
faster to call the "same format" function from 9175d9b7c2.
For numbers, the timings are arbitrarily influenced by how many layers
I add in my testing. With 50 or so layers, a 10x difference is easily
observable though.

Adds initial support for File Handler registration with the python API
for design task #68935. File Handlers will allow developers to associate
additional UI behavior and capability to operators traditionally used
only within the file browser.
The initial commit should have no user visible changes, but will serve
as the foundation for providing file drag & drop capabilities to
operators that can manage files (#111242).
See the PR for an example of python usage.
See design task #68935 for remaining work to be explored in the future.

"mesh" reads much better than "me" since "me" is a different word.
There's no reason to avoid using two more characters here. Replacing
all of these at once is better than encountering it repeatedly and
doing the same change bit by bit.
And improve naming to remove the inconsistent "SCULPT" prefix in
many cases-- removing redundancy between the namespace name
and the function name. The specific names might need to evolve a bit
still, but it's much less annoying not having to type or read the
namespace all the time. I left out some areas with unclear design.
Due to changes in the build environment shader_builder wasn't able to
compile on macOs. This patch reverts several recent changes to CMake files.
* dbb2844ed9
* 94817f64b9
* 1b6cd937ff
The idea is that in the near future shader_builder will run on the buildbot as
part of any regular build to ensure that changes to the CMake doesn't break
shader_builder and we only detect it after a few days.

No functional changes.
Before this PR the interpolation mode of a new keyframe
was read from the User Preference at the deepest level
where the keyframe is created.
In case where this shouldn't be done, the flag
`INSERTKEY_NO_USERPREF` was passed in.
In this case it would fall back to some default values.
In order to make these low level functions
more flexible, the keyframe settings are now passed in.
I've made a new struct `KeyframeSettings` that holds the
* interpolation
* key type
* handle type
and a function `get_keyframe_settings` that allows
you to quickly get this settings struct.
This is a first step that will allow to pass in the
interpolation mode from python in the future.

Node splitting seems to be broken and when triggered it crashes blender. The cause for
this is that SplitNodePair stores a full node and uses assign operators, that can free
unallocated space.
Although node splitting is important for performance point of view, we should reevaluate
how we want node splitting to work.
This PR only disables it, so it won't crash when used.

Problem here is that `BKE_id_attribute_to_index` [which
`BKE_id_attributes_active_set` uses] does not match
`BKE_id_attribute_from_index` which can lead to "wrong" indices (there
are "wrong" layers included while iterating such as ".corner_vert" or
".corner_edge" for faces).
Deeper reason is that `get_domains_types` swaps `ATTR_DOMAIN_FACE` and
`ATTR_DOMAIN_CORNER` (originally introduced in eae36be372 -- but unclear
at this point why this was done). Historically, this was used for operators
[vertex color rotate/inverse] introduced in c75e1598dd & 771a4dee0b,
assumption is that eae36be372 was trying to make this more generic and make
it work for other domains as well (ATTR_DOMAIN_MASK_COLOR -- the tootip
was also changed from "Rotate vertex colors inside faces" to "Rotate color
attributes inside faces"), however, at this point in time the tools clearly only work
for the corner domain (and this was made more specific in ee18b625ca as well).
So now, remove the swapping all together and make
`BKE_id_attribute_from_index` & `BKE_id_attribute_to_index` in sync.
Also change the tooltip of said operators to use "face corner color attribute".

In some cases the value that defines which ID is displayed as white is
mismatched between the original and evaluated mesh. Use the original
as the source of truth, since that's the mesh that's actively edited.
Similar to previous changes for masks and visibility, remove the mutable
pointer to face sets from the sculpt session. With implicit sharing,
this avoids a duplicate copy of face sets on the evaluated object when
face sets aren't edited.
Most retrieval of face sets now goes through the Mesh attribute API
instead of the pointer in sculpt session. This integrates sculpt code
with the rest of Blender, avoiding the need to reinvent things like
basic attribute access.
Similar to previous refactors to mask and visibility operators, refactor
the face set gesture and edit operators to be multithreaded and only
push undo steps and tag updates for actually changed nodes.
There is opportunity for more code deduplication in the future.
For now the aim is to reduce the number of confusing abstraction
levels though.
This avoids having to make the original data layer mutable when we
aren't going to modify it, meaning the memory can still be shared with
the evaluated mesh-- saving 1 byte per face in some situations. This was
made possible by previous commits that moved to using the Mesh attribute
API instead of the SculptSession pointer to edit this data. Eventually the
`hide_poly` pointer should be completely removed.
