This gives a modest speedup as calculating tessellation and face
normals at the same time can be more efficiently multi-threaded.
Also avoids calculating face normals twice,

This commit improves NURBS knot generation by adding proper support
for the combination of the Bezier and cyclic options. In other cases
the resulting knot doesn't change. This cyclic Bezier knot is used to
create accurate accurate "Nurbs Circle", "Nurbs Cylinder" primitives.
"Nurbs Sphere" and "Nurbs Torus" primitives are also improved by
tweaking the spin operator.
The knot vector in 3rd order NURBS curve with Bezier option turned on
(without cyclic) is changed in comparison to previous calculations,
although it doesn't change the curve shape itself.
The accuracy of the of NURBS circle is fixed, which can be checked by
comparing with mesh circle. Tessellation spacing differences in
circular NURBS is also fixed, which is observable with the NURBS
cylinder and sphere primitives. These were causing seam-like effects.
This commit contains comments from Piotr Makal (@pmakal).

Normal layers currently aren't stored in the undo step
mesh storage, since they are not stored in files at all.
However, the edit mesh expects normals to be fully
calculated, and does not keep track of a dirty state.
This patch updates the normals in the BMesh created
by loading an undo step.
Another option would be calculating the normals on
the undo mesh first, which might be better if Mesh
normal calculation is faster than BMesh calculation,
but the preferred method to access vertex normals fails
in this case, because the mesh runtime mutexes are not
initialized for undo-state meshes.

From an error in rBcfa53e0fbeed, the vertex normals in `SculptSession`
seem to be used, but in the case when no "pbvh" is used, the value of
the pointer is never assigned.
Normals were not generally dirty before this "ensure" function with
regular sculpting operations, so this addition shouldn't have any cost.

All other nodes with data type and domain choices have the domain
below the data type. Generally that order makes sense, because it's
consistent with nodes that have no domain drop-down.
|
|
Because this operator is used on original objects, it's best to tag
the normals dirty instead of explicitly calculating them, to avoid
unnecessarily storing normal layers on an original object (since
they might have to be recalculated during evaluation anyway).
There may be other places this change is helpful, but being
conservative is likely better for now.

The new OBJ exporter did not handle object instances.
The fix is to use a dependency graph iterator, asking for instances.
Unfortunately that iterator makes a temporary copy of instance objects
that does not persist past the iteration, but we need to save all the
objects and meshes to write later, so the Object has to be copied now.
This changed some unit tests. Even though the tests don't have instancing,
the iterator also picks up some Text objects as Mesh ones (which is a good
thing), resulting in two more objects in the all_objects.obj file output.

freetype now depends on brotli
|
|
it was harvesting to the zstd folder which
is not where these libs ought to be.
|
|
With object collection properties open there was a huge delay when
switching active objects in a large scene, (~10k objects, ~5m vertices).
This is due to a non-optimal function to query all the collections the object is in.
To solve this the code can be simplified by using `bpy.types.Object.users_collection`
This returns all the collections the object is in removing the need to compute this in python.

The UI team requested adding woff2 support to freetype.
this required a new dependency brotli.
This changes adds brotili to the builder and bumps
freetype to version 2.11.0
As freetype now depends on other libraries, for consistency
all use of ${FREETYPE_LIBRARY} in cmake has been updated to
use ${FREETYPE_LIBRARIES} adjustments have been made in the
windows platform file, all other platforms use cmake's
FindFreeType.cmake which already sets this variable.

This node can scale individual edges and faces. When multiple selected
faces/edges share the same vertices, they are scaled together.
The center and scaling factor is averaged in this case.

Currently there is no way to flip normals in geometry nodes. This node
makes that possible by flipping the winding order of selected faces.
The node is purposely not called "Flip Normals", because normals are
derived data, changing them is only a side effect. The real change is
that the vertex and edge indices in the face corners of every selected
polygon are reversed, and face corner attribute data is reversed.
While there are existing utilities to flip a polygon and its custom
data, this node aims to process an attribute's data together instead
of processing all attributes separately for each index.

This shader needs to use the same interface as the OCIO shader. On Linux
and Windows this seems to be the case. On MacOS however there is a
mismatch that makes the overlay texture to be completely black when
switching to workbench in the Shader workspace.
This is just a temporarily work-around as this should be solved. Due to
the poor GPU debugging facilities on Mac we haven't been able to
pin-point the root cause.

Editing of generic attributes on the original objects in edit modes is
still very limited. However, when applying a geometry nodes modifier
that generates new attributes. These attributes will show up in the
Attributes panel.
Currently, our exporters are not capable of exporting generic attributes.
Therefore, for the time being, a work around is to apply geometry nodes
and then convert a generic attribute to a task specific attribute like a
uv map, vertex group or vertex color layer. Once more parts of Blender
support generic attributes, this will become less important.
Currently, only meshes are supported by the operator. However, it would
be relatively easy to extend it to other geometry types.

There is probably a better solution that's possible, but the few other

This adds a new curve primitive to generate arcs.
Radius mode (default): Generates a fixed radius arc on XY plane
with controls for Angle, Sweep and Invert.
Points mode: Generates a three point curve arc from Start to End
via Middle with an Angle Offset and option to invert the arc.
There are also outputs for arc center, radius and normal direction
relative to the Z-axis.

This fixes a similar issue as the previous commit, but this time the
continuous notifiers would be sent after redoing. E.g. after moving an
object, and then modifying the transform in the "Adjust Last Operation"
panel.

The thumbnail caching continuously sends `ND_SPACE_FILE_PREVIEW`
notifiers via a timer. But this timer was never ended properly after
thumbnails are fully loaded into the cache.
Wouldn't actually cause a refresh or redraw, send and process the
notifiers.
I already tried to avoid this for the asset view template, but
apparently that wasn't working correctly. For the File/Asset Browser I
never applied that fix to avoid possible regressions before the release.

This commit moves code in all node editor files to the
`blender::ed::space_node` namespace, except for C API
functions defined in `ED_node.h`, which can only be moved
once all areas calling them are moved to C++.
The change is fairly straightforward, I just moved a couple
of "ED_" code blocks around to make the namespace more
contiguous, and there's the method for adding a pointer to
a struct in a C++ namespace in DNA.

This patch fixes a correctness issue discovered in the `int4 select(...)` function on Apple Silicon machines, which causes bad bvh2 builds. Although the generated bvh2s give correct renders, the resulting runtime performance is terrible. This fix allows us to switch over to bvh2 on Apple Silicon giving a significant performance uplift for many of the standard benchmarking assets. It also fixes some unit test failures stemming from the use of MetalRT, and trivially enables the new pointcloud primitive.

Custom bones are drawn by instancing the GPUBatch of the base object. To
access the mesh and its GPUBatch, `BKE_object_get_evaluated_mesh` was
used. However, since GPU subdivision support, this will return a
subdivision wrapper which will never be drawn, and thus will have an
invalid batch, which caused the crash.
`BKE_object_get_evaluated_mesh_no_subsurf` should be used instead, to
return the mesh that will be drawn, and have the subdivision evaluated
on the GPU. Note that the rest of the draw code is already using this
function.
