This code in the geometry set header was not directly related to
geometry sets, it makes more sense in the attribute access header.
This makes it clearer that code for geometry components uses attribute
code, rather than the other way around. It also allows adding more
functionality to `BKE_attribute_access.hh` that depends on these things
without including `BKE_geometry_set.hh` there.

The code incorrectly used the size of the second to last segment rather
than the last segment's size. That was a problem when the last segment
is a vector segment but the second to last isn't.
I also used the opportunity to slightly refactor the control point
offsets cache, making it one longer so it also contains information
about the size of the last segment, simplifying other code.

Now the operators work like other areas of Blender using the list of selected objects.
Also, the name has been changed to:
```Layers:
- Copy Layer to Selected
- Copy All Layers to Selected
Materials:
- Copy Material to Selected
- Copy All Materials to Selected```

This fixes a few "obvious" places where we do unnecessary updates.
Those special cases were added in the early days of geometry nodes
when many updates were missing and we tried to get it to work at all.
There is a fairly high risk that with this change some required updates
will be missing again. Those can be fixed when we find thme.
Some of the update issues might have been fixed by rB58818cba40794905f9323080e60884e090f2d388
and similar changes we added over time.

Sculpting tools are designed to ignore hidden geometry and behave like
hidden geometry does not exist.
When getting the neighbors of a vertex, now this takes into account
hidden geometry to avoid returing neighbors which connected edge is not
visible. This should make corner cases of a lot of tools work properly,
especially when working in low poly meshes when is common to have a
single face loop hidden.

Previously, multiple threads adding information to node ui storage
at the same time resulted in memory corruption. The lock prevents
that, but might potentially become a bottleneck in the future.
For now favour correctness over a potential performance bottleneck.

By rearranging a few variables we can remove redundant specifiers

Not allowing external direct access to the vector of splines in the
curve will help for things like reallocating custom data when a spline
is added or removed.

This commit exposes the first spline control point attributes. The
implementation incorporates the attributes into the virtual array
system, providing efficient methods to flatten the data into a
contiguous array and to apply changes from a flattened array. This
is only part of the eventual goal, which includes changes to run
attribute nodes separately for each spline to completely avoid copying.
So far `tilt` and `radius`, the two generic attributes common to
all spline types, are implemented. The more complex `position`
attribute is also added. It requires some special handling for Bezier
splines, where the control point handles need to be moved along with
the control points. To make that work I also added automatic handle
recalculation to the Bezier spline.

With Constrain to Image Bounds selected, UVs will be constrained to the
correct/closest UDIM if the image is tiled.
UVs will be constrained to the 0-1 UV space if the image is not tiled.
This will override the present behavior of always constraining selected
UVs to the 0-1 UV space (UDIM 1001).

The sockets are not exposed in any nodes yet.
They work similar to the Object/Collection sockets, which also

Extracts `nlasnapshot_blend_get_inverted_upper_snapshot()` from
`BKE_animsys_nla_remap_keyframe_values()`
This introduces a new struct member:
`NlaEvalChannelSnapshot->remap_domain` and marks which values of
`blended_snapshot` are processed for remapping/used-for-inverting.
Effectively, it marks which values have successfully been remapped and
can be further used for remapping.
`nlasnapshot_blend_get_inverted_upper_snapshot()`:
output snapshot `r_upper_snapshot` has each channel's `remap_domain`
written to which effectively marks the successfully remapped values.
The only reason a value is not in the remap domain is if inversion
failed or it wasn't marked to be remapped.
`..get_inverted_upper_snapshot()` has a variant `nlasnapshot_blend()`
from {D10220}, but this patch doesn't depend on it at all. A third
variant will later be added `..get_inverted_lower_snapshot()`.
Altogether, these three functions allow solving for any of
(lower_snapshot, upper_snapshot, blended_snapshot) given the other two.
The function `..get_inverted_lower_snapshot()` will also similarly
process the remap domain of the blended and lower snapshot.
added assertions within `nlasnapshot_blend()` and
`..get_inverted_upper_snapshot()` to future proof branches dealing with
blendmode and mixmodes. (suggested by sybren)

The order was arbitrary, and rearranging the declarations

The last point of the output was at the same location as the
first point of a cyclic spline. The fix is simple, just account for
the cyclic when choosing the sample edge length, and don't
hard code the last sample.
|
|
The spline `length` function assumed that the curve always had evaluated
edges. That is clearly false. This commit adds a check to `length` and a
special case for a single point in the curve resample node.
|

This commit uses two changes to improve the performance of the point
instance node.
**Prevent Reallocations**
At 64 bytes, the transform matrix for every instance is rather large,
so reallocating the vector as it grows can become a performance bottle-
neck. This commit reserves memory for the instances that will be added
to prevent unecessary reallocations as the instance vector grows.
In a test with 4 million instances of 3 objects in a collection, the
node was about 40% faster, from 370ms to 270ms for the node.
**Parallelization**
Currently the instances are added by appending to a vector. By changing
this slightly to fill indices instead, we can parallelize the operation
so that multiple threads can fill data at the same time. Tested on a
Ryzen 3700x, this reduced the runtime from the above 270ms to 44ms
average, bringing the total speedup to ~8x.
Note that displaying the instances in the viewport is still much slower
than the calculations in node, this change doesn't affect that.
|
|
Those were mostly just left over from previous work on particle nodes.
They solved the problem of keeping a reference to an object over
multiple frames and in a cache. Currently, we do not have this problem
in geometry nodes, so we can also remove this layer of complexity
for now.
|
|
We need to always add a single point to the last cyclic segment that
completes the loop, because that includes the starting point of the
evaluated edge. The existing code forgot about that point.
|
|
This node generates a naturally parametarized (even length edge) poly
spline version of every spline in the input. There are two modes,
"Count", and "Length". These are similar to the same options for the
line primitive node in end points mode.
I implemented this instead of a "Sample Points" node, because for this
operation it's trivial to keep the result as a curve, which is nice
since it increases flexibility, and because it can make instancing
simpler, i.e. using the transforms of each evaluated point rather than
requiring the construction of a "rotation" attribute.

this is a followup to rB2bd85d9cc623, we cannot forcefully delete

of resync.
Logs are not enough here, we need proper warning visible for the user.
|
|
This is the opposite of previous code, which would keep those
'deprecated' overrides arround (often in a dedicated collection), when
they were detected as user-edited.
While this is a safe-ish way to (try to) preserve user-edited data, this
tends to add too much 'trash' data to production scenes, which cleaning
becomes a burden.
Note that user will get warnings in thos cases, and can always choose
not to save the current blend file and go fix the library issue instead.
|
|
Code detecting overrides which reference linked data is missing was
actually missing many cases, leading to too much garbage data being kept
around after resync process.
|
|
This node has the same functionality as the color and vector curve
mapping nodes in the shader editor. Here is works on every value for
the selected attribute, and it can also output a float value. Other
than that, the implementation is quite straightforward-- almost
completely boilerplate code.
