These functions used internal values and only really make sense in
the context of the mesh validation process where they're used to remove
invalid elements from the mesh.
Note: Applies to both UV Sphere Projection and UV Cylinder Projection.
Adds a new boolean option "Preserve Seams" to UV Sphere Projection.
With "Preserve Seams" active, the Sphere projection will do a
greedy flood fill over the 3D topology, stopping at 3D boundaries
and also stopping at edges where "Mark Seam" has been used in the
3D Viewport.
During the flood fill, each face is mapped using the spherical
projection and then adjusted along the U axis so the UV map is
continuous across the shared edge.
With careful seam placement, this allows for the creation of a
spiral-cut-orange-peel unwrap, where a sphere can be unwrapped
into a single long continuous strip, wrapping multiple times around
the object.
Finally, if the flood fill process creates multiple UV Islands,
they are spaced along the `U` axis to prevent overlaps.

With the goal of clearly differentiating between arrays and single
elements, improving consistency across Blender, and using wording
that's easier to read and say, change variable names for Mesh edges
and polygons/faces.
Common renames are the following, with some extra prefixes, etc.
- `mpoly` -> `polys`
- `mpoly`/`mp`/`p` -> `poly`
- `medge` -> `edges`
- `med`/`ed`/`e` -> `edge`
`MLoop` variables aren't affected because they will be replaced
when they're split up into to arrays in #104424.
This offers overflow checking in debug builds, avoids implicit
conversion to pointers, slicing features for future convenience,
and clarifies ownership. Also switch naming to plural like most
other arrays for further clarification.
This check is no longer needed as Campbell has removed the need to
pass around the active window. This check could potential be error-
hiding so best removed if not needed.
Pull Request #105351
This pull request adds a new tipe of resource handles (thin handles).
These are intended for cases where a resource buffer with more than one
entry for each object is needed (for example, one entry per material
slot).
While it's already possible to have multiple regular handles for the
same object, they have a non-trivial overhead in terms of uploaded
data (matrix, bounds, object info) and computation (visibility
culling).
Thin handles store an indirection buffer pointing to their "parent"
regular handle, therefore multiple thin handles can share the same
per-object data and visibility culling computation.
Thin handles can only be used in their own Pass type (PassMainThin),
so passes that don't need them don't have to pay the overhead.
This pull request also includes the update of the Workbench Next
pre-pass to use PassMainThin, which is the main reason for the
implementation of this feature.
The main change from the previous PR is that the thin handles are now
stored directly in the main resource_id_buf, to avoid wasting an extra
bind slot.
Pull Request #105261
Add specific modal keyitem for `Vert/Edge Slide` and `TrackBall`.
So they don't need to reuse modal items from other operators.
Note that there is a workround to avoid repeated keys in the status bar.
In `gesture_box_apply`, check if `exec` function returns
`OPERATOR_CANCELLED` and return 0 to prevent any undo items from being
created.
Pull Request #105065
Applied for the motion tracking data data structures.
There are two advantages of doing so:
- More explicit and platform independent way of indicating that
something is legacy and is not to be accessed outside of the
versioning code.
- Simplifies conversion to C++ where having deprecated fields
triggers warning in implicitly defined assign operator.

3e5ce23c99 introduced a regression in case the freed Main was part of a
list, and was supposed to be removed from it, since calling
`BLI_remlink` does _not_ clear the `prev`/`next` pointers of the removed
link.
This commit also contains a few more tweaks to recent related b3f42d8e98
commit.
While this behavior can be useful in some cases, it can also create
issues (as in one of own recent commits, 3e5ce23c99), since it
implicetly keeps the removed linknode 'linked' to the listbase.
At least warn about it in the documentation of `BLI_remlink`.
The active window was used by the NLA and the Graph editor however
this is not always available and not necessarily the window that
contains the area being initialized. Potentially causing the graph and
NLA spaces to be initialized with the wrong scene.
Active window access caused various awkward fixes in the past
([0], [1], [2]) which worked around the active window not being set.
Use a lookup for the window instead of accessing the active window.
Note that passing the window is an option too however this is only
used for versioning older files and is not be needed in most cases.

As part of #95966, move the `ME_SEAM` flag on mesh edges
to a generic boolean attribute, called `.uv_seam`. This is the
last bit of extra information stored in mesh edges. After this
is committed we can switch to a different type for them and
have a 1/3 improvement in memory consumption.
It is also now possible to see that a mesh has no UV seams in
constant time, and like other similar refactors, interacting with
only the UV seams can be done with less memory.
The attribute name starts with a `.` to signify that the attribute,
like face sets, isn't meant to be used in arbitrary procedural
situations (with geometry nodes for example). That gives us more
freedom to change things in the future.
Pull Request #104728
This commit introduces a new Main boolean flag that marks is as invalid.
Higher-level file reading code does checks on this flag to abort reading
process if needed.
This is an implementation of the #105083 design task.
Given the extense of the change, I do not think this should be
considered for 3.5 and previous LTS releases.
GPUBatch.draw supports basic drawing methods. Although all
supported GPU backends support range based and instance based drawing.
This patch adds 2 methods to GPUBatch to add support to range based and
instance based drawing.
my_batch.draw_range(my_shader, elem_start=10, elem_count=5)
Will draw my_batch using my_shader. From the attached index buffer
elements 10-14 will be drawn.
my_batch.draw_instance_range(my_shader, instance_start=0, instance_count=10)
will draw my_batch using my_shader 10 times. Inside the vertex
shader the current instance number is held by gl_InstanceID.

1. Changes the subdivision function to not fill in time but add 0 to fix bug #104824
2. Fixes a bug in sanitization function noticed while fixing this bug.
Pull Request #105306
Add a hash for faster look-ups on collection->gobject,
This avoids a full list lookup for every object added via Python's
CollectionObject.link as well as linking via BKE_collection_object_add_*
functions.
While the speedup is non-linear, linking & unlinking 100k objects from
Python is about 50x faster. Although unlinking all objects in order
(a best-case for linked lists) is approximately the same speed.

Rewrite the logic to depend less on local variables and prefer spans
and indices over points and pointer arithmetic. Also make use of the
IndexRange type for some basic logic, correct the mesh that the
sharp edge layer was chosen from, and reduce variable scope.
The material indices from the caps were only copied if the base mesh had
a material index attribute. Fix that by copying them manually if the cap
has the attribute.
Search list's region is having its size members (winx and winy) set
to values that are one pixel too small. This causes text to look bad
as they are slightly off their pixel alignment.
See #105308 for more details and an illustration of the issue.
