This implements the MVP for the new spreadsheet editor (T85879). The functionality
is still very limited, but it proved to be useful already. A more complete picture
of where we want to go with the new editor can be found in T86279.
Supported features:
* Show point attributes of evaluated meshes (no original data, no other domains,
no other geometry types, yet). Since only meshes are supported right now, the
output of the Point Distribute is not shown, because it is a point cloud.
* Only show data for selected vertices when the mesh is in edit mode.
Different parts of Blender keep track of selection state and original-indices with
varying degrees of success. Therefore, when the selected-only filter is used, the
result might be a bit confusing when using some modifiers or nodes. This will
be improved in the future.
* All data is readonly. Since only evaluated data is displayed currently, it has to
be readonly. However, this is not an inherent limitation of the spreadsheet editor.
In the future editable data will be displayed as well.
Some boilerplate code for the new editor has been committed before in
rB9cb5f0a2282a7a84f7f8636b43a32bdc04b51cd5.
It would be good to let the spreadsheet editor mature for a couple of weeks as part
of the geometry nodes project. Then other modules are invited to show their own data
in the new editor!

Properties Editor
Since rBb279fef85d1a, the nodes properties for geometry nodes using a
texture are displayed in the Properties Editor.
rB85421c4fab02 added an attribute search button, but this was missing
still (gave just the regular text button) if this was displayed in the
Properties Editor.

Otherwise muting a Join Geometry node has no effect, when there
are multiple Join Geometry nodes in a row.
|
|
Using EEVEE (as well as some other actions like saving the file or
tweaking mesh parameters) can cause a PBVH rebuild. The different sculpt
tools can store PBVH nodes or other related data in their caches, so
this data becomes invalid if the PBVH rebuilds during evaluation. This
ensures that the PBVH does not rebuild while the cache of Expand is
being used, like it already happens for brushes and filters.

Adds toggle to graph editor (View->Show Extrapolation). When disabled,
then fcurves only draw over the keyframe range. For baked fcurves and
ghost fcurves, the range is all sampled points.
It is intended for frequent use so anybody could assign hotkey or add
to quick favorites that's why GE-View is the best place for it.
Show Extrapolation is the default.

This commit adds interpolation to and from attribute on the polygon
domain. Interpolation is done automatically when a node uses attributes
on two different domains. The following are the new interpolations and
corresponding simple test cases:
- **Point to Polygon**: Painting the shade smooth attribute in weight
paint mode
- **Polygon to Point**: Moving points along a normal based on the
material index
- **Polygon to Corner**: Scaling a UV map with the material index
before sampling a texture
{F9881516}
This is also necessary for an improved implementation of the `normal`
attribute.

This patch exposes the "Shade Smooth" value as a boolean attribute.
This setting is exposed as a check-box in the mesh data properties,
but the value is actually stored for every face, allowing some faces
to be shaded smooth with a simple per-face control.
One bonus, this allows at least a workaround to the lack of control
of whether meshes created by nodes are shaded smooth or not: just use
an attribute fill node.

Prior to rB99a7c917eab7, Shift + D was used to set detail size for both
constant and relative detail (using radial control). The commit added an
improved operator for doing this for constant detail (showing the
triangle grid representation), but left the user without a shortcut to
do this for relative detail.
Interestingly rB99a7c917eab7 only changed this for the Blender keymap,
the Industy Compatible keymap still has the "old" entry.
This patch changes both keymaps to have both entries.
For user experience, the real change here is to have both available on
one 'primary' shortcut (Shift+D), the improved
'dyntopo_detail_size_edit' operator will now act on all possible cases.
If it deals with constant detail, it acts as before, if it deals with
relative detail etc, it will fallback to the "old" way of doing it via
radial control instead. I assume this adresses what was stated in
rB99a7c917eab7: "Deciding if both detail sizes can be unified needs a
separate discussion"
Also, move dyntopo_detail_size_edit to sculpt_detail.c

- Use property split (and therefore decorators)
- Declare sublayout variables after getting modifier info

This was meant to be part of rB9ce950daabbf, but the change dropped from

This makes the following changes to the name of the two
geometry nodes subvision nodes:
- `Subdivision Surface` -> `Subdivide Smooth`
- `Subdivision Surface Simple` -> `Subdivide`
Most of the benefit is that the names are shorter, but it also better
mirrors the naming of operations in edit mode, and phrases the names
more like actions. This was discussed with the geometry nodes team.

with many objects
When you have many distinct objects, in an Eevee render then the shadow caster gets exponentially slower as the number of (distinct) objects increase.
This is because of the way that frontbuffer->bbox (EEVEE_BoundBox array) and the associated frontbuffer->update bitmap are resized.
Currently the resizing is done by reserving space for SH_CASTER_ALLOC_CHUNK (32) objects at a time.
When the number of objects is large, then the MEM_reallocN() gets progressively slower because it must memcpy the entire bbox/bitmap data to the new memory chunk.
And there will be a lot of *memcpy* operations for a large scene.
(Obviously there are a significant number of memory allocations/deallocations too - though this would be linear performance.)
I've switched to doubling the frontbuffer->alloc_count (buffer capacity) instead of adding SH_CASTER_ALLOC_CHUNK (32). As I understand this is the only way to eliminate exponential slowdown. Just increasing the size of SH_CASTER_ALLOC_CHUNK would still result in exponential slowdown eventually.
In other changes, the "+ 1" in this expression is not necessary.
if (id + 1 >= frontbuffer->alloc_count)
The buffer is 0-based. So when the buffer is initially allocated then id values from bbox[0] to bbox[31] are valid. Hence when frontbuffer->count == frontbuffer->alloc_count, is when the resizing should be triggered.
As it stands the "+ 1" results in resizing the buffer, when there is still capacity for one more object in the buffer.
I've changed the initial buffer allocation to use MEM_mallocN() instead of MEM_callocN(). The difference is that malloc() doesn't memset buffer (with zeros) when allocated. I've checked the code where new bbox records are created, and it does not rely on the buffer being initialised with zeros.
Anyway, isn't calloc() safer than using malloc()? Well no, it's actually the opposite in this case. Every time the buffer size is increased, it is done using realloc(), and this does not zero-out the uniniitialised portion of the buffer. So the code would break if it was modified to assume that the buffer contains zeros. Hence I believe initialising the buffer using calloc() could be misleading to a new developer.
Won't this result in increased memory usage? Yes, if you have millions of objects in your scene, then you are potentially using up-to twice the memory for the shadow caster. (However if you have millions of objects in your scene you're probably finding the Eevee render times a slow.)
Note that once the render gets going the frontbuffer bbox/bitmap will be shrunk to a multiple of SH_CASTER_ALLOC_CHUNK (32), therefore releasing the overallocation of memory.
As observed in Visual Studio - this appears to be prior to peak memory usage anyway.
Note this shrinking is executed in EEVEE_shadows_update() - during the first render sample pass. If necessary you could consider shrinking the buffer immediately after the EEVEE_shadows_caster_register() has done it's work. (Note however it appears you would need to add that function call is multiple places.)
Anyway as per the bug report I raised, I observed a 5% increase in peak-memory. And I'm unclear whether this difference in memory is due to me running the debug build. (It could be that there is no difference because of the shrinking.)
I couldn't figure out how the shadow caster backbuffer works. I see that EEVEE_shadows_init() has an explicit command to swap the front/back buffers. However this is done only when the buffers are first initialised and there is nothing in there yet. In my testing, the backbuffer->count was always zero, EEVEE_shadows_update() never did anything with the backbuffer.
Finally this problem is most evident when using Geometry Nodes or a Particle System to instantiate many objects. Objects created through say the array modifier do not cause any issues because it is considered one object by the shadow caster.

This commit refactors the point distribute node to skip realizing
the instances created by the point instance node or the collection
and object info nodes. Realizing instances is not necessary here
because it copies all the mesh data and and interpolates all
attributes from the instances when this operation does not
need to modify the input geometry at all.
In the tree leaves test file this patch improves the performance of
the node by about 14%. That's not very much, the gain is likely larger
for more complicated input instances with more attributes (especially
attributes on different domains, where interpolation would be necessary
to join all of the instances). Another possible performance improvement
would be to parallelize the code in this node where possible.
The point distribution code unfortunately gets quite a bit more
complicated because it has to handle the complexity of having many
inputs instead of just one.
Note that this commit changes the randomness of the distribution
in some cases, as if the seed input had changed.

Splits up `tree_element_id.cc`/`tree_element_id.hh`.
If we move all ID types into this one file, it will become rather big. Smaller
files are probably easier to work with. We could still keep small classes like
`TreeElementIDLibrary` in the general file, don't mind really, but this creates
separate files for that too.
|
|
These files can contain more than just the "base" tree element types. E.g. the
class for the view-layer base element can also contain the class for the
view-layer elements. Otherwise we'd end up with like >50 files for the
individual types, most of them very small.
So just give the files a general name and put the related classes in there.

code design
Continuation of work in 2e221de4ceee, 249e4df110e0 and 3a907e742507.
Adds new tree-element classes for the scene-ID, scene collections, scene
objects, and the view layers base.
There is some more temporary stuff in here, which can be removed once we're
further along with the porting. Noted that in comments.

Currently the implementations specific to each geometry type are in
the same file. This makes it difficult to tell which code is generic
for all component types and which is specific to a certain type.
The two files, `attribute_access.cc`, and `geometry_set.cc` are
also getting quite long.
This commit splits up the implementation for every geometry component,
and adds an internal header file for the common parts of the attribute
access code. This was discussed with Jacques Lucke.

This was due to the AO random sampling using the same "seed" as
the AA jitter. Decorelating the noise fixes the issue.
|
|
The actual sample count is rounded up to a multiple of 4 because we
sample 4 horizons directions.
Changing this setting forces the shader to recompile (because using a
GPU_constant).
|
|
This just bypass the occlusion computation if there is no occlusion
data. This avoids weird looking occlusion due to the screen space
geometric normal reconstruction.
|
|
The sampling is now optimum with every samples being at least one pixel
appart. Also use a squared repartition to improve the sampling near the
center.
This also removes the thickness heuristic since it seems to remove
a lot of details and bias the AO too much.
|
|
This is useful for debugging raycasting.
|
|
This is a major rewrite that improves the screen space raytracing
a little bit.
This also decouple ray preparation from raytracing to be reuse in other
part of the code.
This changes a few things:
- Reflections have lower grazing angle failure
- Reflections have less self intersection issues
- Contact shadows are now fully opaque (faster)
Unrelated but some self intersection / incorrect bad rays are caused by
the ray reconstruction technique used by the SSR. This is not fixed by
this commit but I added a TODO.
|
|
This removes the need for per mipmap scalling factor and trilinear interpolation
issues. We pad the texture so that all mipmaps have pixels in the next mip.
This simplifies the downsampling shader too.
This also change the SSR radiance buffer as well in the same fashion.
