This commit adds a search menu when links are dragged above empty
space. When releasing the drag, a menu displays all compatible
sockets with the source link. The "main" sockets (usually the first)
are weighted above other sockets in the search, so they appear first
when you type the name of the node.
A few special operators for creating a reroute or a group input node
are also added to the search.
Translation is started after choosing a node so it can be placed
quickly, since users would likely adjust the position after anyway.
A small "+" is displayed next to the cursor to give a hint about this.
Further improvements are possible after this first iteration:
- Support custom node trees.
- Better drawing of items in the search menu.
- Potential tweaks to filtering of items, depending on user feedback.
Thanks to Juanfran Matheu for developing an initial patch.

This node outputs the current scene time in seconds or in frames.
Use of this node eliminates the need to use drivers to control values
in the node tree that are driven by the scene time.
Frame is a float value to provide for subframe rendering for motion
blur.

The original move to c++ that the other commits depended upon had some issues
that should be fixed before committing it again. The issues were reported in
T93797, T93809 and T93798.
We should also find a better rule for not using c-style casts going forward,
although that wouldn't have been reason enough to revert the commits.
Introducing something like a `MEM_new<T>` and `MEM_delete<T>`
function might help with the the most common case of casting the return
type of `MEM_malloc`.
Going forward, I recommend first committing the changes that don't
require converting files to c++. Then convert the shading node files
in smaller chunks. Especially don't mix fairly low risk changes like
moving some simple nodes, with higher risk changes.

This improves both code finding, for example "color ramp" now has its own file.
And now each node has its own namespace so function names can be simplified
similar to rBfab39440e94
This commit also makes all file names use snake case instead of camel case.

This helps to tell when a pointer is expected to be null, and avoid
overly verbose code when dereferencing. This commit also includes
a few other cleanups in this area:
- Use const in a few places
- Use `float2` instead of `float[2]`
- Remove some unnecessary includes and old code
The change can be continued further in the future.

This node calculates the dual of the input mesh. This means that faces
get replaced with vertices and vertices with faces. In principle this
only makes sense when the mesh in manifold, but there is an option to
keep the (non-manifold) boundaries of the mesh intact.
Attributes are propagated:
- Point domain goes to face domain and vice versa
- Edge domain and Face corner domain gets mapped to itself
Because of the duality, when the mesh is manifold, the attributes get
mapped to themselves when applying the node twice.
Thanks to Leul Mulugeta (@Leul) for help with the
ascii diagrams in the code comments.
Note that this does not work well with some non-manifold geometry,
like an edge connected to more than 2 faces, or a vertex connected to
only two faces, while not being in the boundary. This is because there
is no good way to define the dual at some of those points. This type
of non-manifold vertices are just removed for this reason.

Replace compare floats node with a generalized compare node. The node
allows for the comparison of float, int, string, color, and vector.
The datatypes support the following operators:
Float, Int: <, >, <=, >=, ==, !=
String: ==, !=
Color: ==, !=, lighter, darker
(using rgb_to_grayscale value as the brightness value)
Vector Supports 5 comparison modes for: ==, !=, <, >, <=, >=
Average: The average of the components of the vectors are compared.
Dot Product: The dot product of the vectors are compared.
Direction: The angle between the vectors is compared to an angle
Element-wise: The individual components of the vectors are compared.
Length: The lengths of the vectors are compared.

The main goal of this refactor is to make BPath module use `IDTypeInfo`,
and move each ID-specific part of the `foreach_path` looper into their
own IDTypeInfo struct, using a new `foreach_path` callback.
Additionally, following improvements/cleanups are included:
* Attempt to get better, more consistent namings.
** In particular, move from `path_visitor` to more standard `foreach_path`.
* Update and extend documentation.
** API doc was moved to header, according to recent discussions on this
topic.
* Remove `BKE_bpath_relocate_visitor` from API, this is specific
callback that belongs in `lib_id.c` user code.
NOTE: This commit is expected to be 100% non-behavioral-change. This
implies that several potential further changes were only noted as
comments (like using a more generic solution for
`lib_id_library_local_paths`, addressing inconsistencies like path of
packed libraries always being skipped, regardless of the
`BKE_BPATH_FOREACH_PATH_SKIP_PACKED` `eBPathForeachFlag` flag value,
etc.).
NOTE: basic unittests were added to master already in
rBdcc500e5a265093bc9cc.

Two issues addressed here:
I) `asset_type_info` is sub-data, not a callback. Therefore, move it
before the callbacks in the `IDTypeInfo` struct.
II) More important, initialize this new attribute in *ALL* `IDTypeInfo`
instances. No member of this struct should ever be left implicitely
uninitilazed, ever.

Previously, node types had a callback that creates internal links. Pretty
much all nodes used the same callback though. The exceptions are the
reroute node (which probably shouldn't be mutable anyway) and some
input/output nodes that are not mutable.
Removing the callback helps with D13246, because it makes it easier
to reason about which internal links are created and when they change.
In the future, the internal links should be part of the node declaration.
|
|
This cleans up part of the code that still set the flag manually. Also, this
change helps with D13246 because it makes it easier to tag the node
tree as changed when the availability of a socket changed.

Those functions were more useful when `FieldInferencingInterface`
was still declared further down in `node.cc`.

Cause of this issue is that Custom Node Sockets info type was
initialized as SOCK_FLOAT when registering. Areas within the core that
would ignore custom socket types by checking its type would use the
socket as being a float type.
When custom node sockets have a property called default_value blender
tries to store it as an internal default value what failed in debug
builds.
This patch will set the socket type to SOCK_CUSTOM when registering a
custom socket type and allow, but skip storage of custom default values.
In this case the default values should already be stored as custom
properies.

Previously both `.` and `_` were used as separators when finding
a unique name for a socket. This removes the use of `.`, since `_`
was more common. It also does versioning for all of a file's node
trees to make sure that they all use the `_` convention.

Currently, when creating a new node tree ID, its `typeinfo` is set to
`NodeTreeTypeUndefined`, but its `type` enum value is left to `0`,
aka `NTREE_SHADER`.
This patch adds a new `NTREE_UNDIFINED` value, and use it for
`NodeTreeTypeUndefined` types of node trees.
NOTE: While it is not clear whether that actually fixes issues currently,
quite a bit of code still relies on the value of `type`, so think it
makes sense to sanitize this.
NOTE: Would have been ideal to reserve `0` value to undefined type,
but at this point this is not possible anymore, so chose to use `-2` instead.

Previously, to get the declaration of a socket, one had to go
through `node->declaration`. Now this indirection is not necessary
anymore. This makes it easier to add more per-socket information
into the declaration and accessing it in various places.
Currently, this system is used by socket descriptions and node warnings
for unsupported geometry component types.

Previously, `ImageTile->ok` and `ImageUser->ok` were used to indicate
whether an image failed to load. There were three possible values
which (probably) had the following meanings:
* `0`: There was an error while loading the image. Don't try to load again.
* `1`: Default value. Try to load the image.
* `2`: The image was loaded successfully.
This image-wide flag did not make sense unfortunately, because loading
may work for some frames of an image sequence but not for others.
Remember than an image data block can also contain a movie.
The purpose of the `->ok` flag was to serve as an optimization to avoid
trying to load a file over and over again when there is an error (e.g. the
file does not exist or is invalid). To get the optimization back, the patch
is changing `MovieCache` so that it can also cache failed load attempts.
As a consequence, `ibuf` is allowed to be `NULL` in a few more places.
I added the appropriate null checks.
This also solves issues when image sequences are used with the
Image Texture node in Geometry nodes (also see D12827).

The new `BKE_LIB_FOREACHID_PROCESS_FUNCTION_CALL` execute the given
statement and then check status of `LibraryForeachIDData` data, and
return in case stop of iteration is requested.
This is very similar to the other `BKE_LIB_FOREACHID_PROCESS_` existing
macros, and allows us to properly break iteration when a sub-function
has requested it.

These nodes allow accessing and changing the stable/random ID used
for motion blur with instances and stable randomness.
Since rB40c3b8836b7a, the stable ID is a built-in attribute, so to be
consistent and allow changing it in the node tree like other built-in
attributes, it has get and set nodes.

In future use cases, a volume can contain many grids that represent the
density information. In this case, it's better if the volume to mesh node
creates a mesh based on all of the grids in the volume.
This is also a benefit to share-ability, since one doesn't have to
specify the grid name in the node. Instead, in the future we can have
a way to split particular grids into separate volumes, if only one
grid should be considered.
The code changes are relatively simple:
- Move the old volume to mesh node to the legacy folder.
- Run the volume to mesh node on all instance geometry, like elsewhere.
- Make the blenkernel's volume to mesh API a bit more specific.

This adds a new image texture node for geometry nodes. It does not
reuse the same node that is used in shading, because we want to be
able to expose the image and frame as sockets.
There is a known update issue when a movie or image sequence is
used. That will be fixed separately (also see D12957).
Currently, the image socket is just a pointer to an Image ID data block.
This can contain single images but also movies and image sequences.
In the future, the definition of an image socket can be expanded to
include images that are generated from scratch in the node tree.
For more details read the discussion in D12827.
Some of the code is a direct port from cycles and should be cleaned
up a bit in the future. For example `image_cubic_texture_lookup`.
For still images, the frame input is ignored. Otherwise, the frame
has to be in a valid range for the node to work. In the future we
may add e.g. automatic looping functionality.

This node takes a geometry set with instances as input and outputs
points located on the origins of the top level of instances in the
geometry set (not nested instances). It also has position and radius
inputs to allow overriding the default, and a selection input to only
generate points for some instances.
The use case for this node is a method to use geometry proximity on
instance origins, but in a more generic way that is flexible and useful
in other situations.
