Some nodes didn't check the type of the link's socket for filtering.
Do this with a combination of manually calling the node tree's validate
links function and using the helper function for declarations.
Also clean up a few cases that added geometry sockets manually
when they can use the simpler helper function.
|

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.

The `node_storage` functions to retrieve const and mutable structs
from a node are generated by a short macro that can be placed at the
top of each relevant file. I use this in D8286 to make code snippets
in the socket declarations much shorter, but I thought it would be
good to use it consistently everywhere else too.
The functions are also useful to avoid copy and paste errors,
like the one corrected in the cylinder node in this commit.

With this commit, we no longer use the prefixes for every node type
function like `geo_node_translate_instances_`. They just added more
places to change when adding a new node, for no real benefit.

This puts all static functions in geometry node files into a new
namespace. This allows using unity build which can improve
compile times significantly (P2578).
* The name space name is derived from the file name. That makes
it possible to write some tooling that checks the names later on.
The file name extension (`cc`) is added to the namespace name as
well. This also possibly simplifies tooling but also makes it more
obvious that this namespace is specific to a file.
* In the register function of every node, I added a namespace alias
`namespace file_ns = blender::nodes::node_geo_*_cc;`. This avoids
some duplication of the file name and may also simplify tooling,
because this line is easy to detect. The name `file_ns` stands for "file
namespace" and also indicates that this namespace corresponds to
the current file. In the beginning I used `node_ns` but `file_ns` is more
generic which may make it more suitable when we want to use unity
builds outside of the nodes modules in the future.
* Some node files contain code that is actually shared between
different nodes. For now I left that code in the `blender::nodes`
namespace and moved it to the top of the file (couldn't move it to
the bottom in all cases, so I just moved it to the top everywhere).
As a separate cleanup step, this shared code should actually be
moved to a separate file.

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.

Building on the work in rBef45399f3be0, this commits adds
tooltips to the inputs for the default primitives nodes.

As part of the refactor to the node declaration builders, we had hoped
to add a regular expression specifically for these socket names, but
recent discussions have revealed that using the translation marker
macros is the preferred solution.
If the names and descriptions were exposed to RNA, these would not
be necessary. However, that may be quite complicated, since sockets
are all instances of the same RNA types.

This is a followup to rB827d7e7d252d48. After this we should
be consistent everywhere with the hints in the names of geometry
sockets.

The new API introduced in rB1e69a25043120c provides a shorted, more
flexibly way to declare node socket inputs and outputs. This commit
updates all geometry nodes to use the `NodeSocketBuilder` API, except
the four nodes that need `SOCK_HIDE_VALUE` or `SOCK_MULTI_INPUT`.

This mesh primitive enhances the Cube mesh primitive and allows the
creation of a cuboid with a configurable size and number of vertices
in all 3 directions. The Cube primitive is now similar to the Grid
primitive except that it works in 3 dimensions.
Previously it was possible to create a cube and scale it arbitrarily
along each axis. You could also subdivide the mesh, but the number of
subdivisions was equal along all axes. This meant that making the basic
frame for something like modular buildings wasn't trivial.
Inspired by tutorials and files for modular building creation.
The cuboid is created as a `Mesh` so that large meshes with millions of
faces are created quickly. Though edge calculation could be faster if
implemented here, edges are calculated using `BKE_mesh_calc_edges`
to reduce complexity, and in hopes that they may be calculated lazily
for `Mesh` in the future like vertex normals.
See the differential revision for more information.

Some mesh primitives created using geometry nodes use loops to create
vertices and accumulates positions/angles in FP variables. This allows
rounding errors to accumulate and can introduce significant errors.
To minimize changes from original implementation, variables allowing
errors to accumulate are replaced by: delta * index. Affected Mesh
Primitives nodes are Line, Grid, Cylinder, Circle, Cone, and UV-Sphere.

Rename the mesh circle to "Mesh Circle", mesh line to "Mesh Line",
and mesh subdivide to "Mesh Subdivide". Previously they looked exactly
the same in the search menu, and the nodes themselves had the same
label. This is a "deep" rename that also renames internal defines and
function names to match the UI.

Some of the primitive nodes can return null in an error condition.
This is confusing mixed with adding a maderial slot in calling
functions. This is the second crash caused by that confusion. It's
simpler to add the slot right when allocating the mesh, and it will
lend itself better to copy & paste coding in the future.

This fixes T88455 by adding an empty material slot to newly
generated meshes. This allows the object to overwrite the
"default" material without any extra nodes. Technically,
all polygons reference the material index 0 already, so it
makes sense to add a material slot for this material index.

Counts of less than one weren't allowed in end points mode mostly to
avoid a division by zero when calculating the delta. It's trivial to
allow a count of one, so this commit does that, with the point placed
at the start location.

This commit includes nodes to build the following primitives:
- Cone
- Cylinder
- Circle
- Cube
- UV Sphere
- Ico Sphere
- Line
- Plane/Grid
In general the inputs are the same as the corresponding operators
in the 3D view.
**Line Primitive**
The line primitive has two modes-- adding vertices between two end
points, or adding vertices each at an offset from the start point.
For the former mode, there is a choice between a vertex count
and a distance between each point.
**Plane Primitive**
This commit includes the "Plane" and "Grid" primitives as one node.
Generally primitives are named after the simpler form of the shape they
create (i.e. "Cone" can make some more complex shapes). Also, generally
you want to tweak the number of subdivisions anyway, so defaulting to
plane is not an inconvenience. And generally having fewer redundant
base primitives is better.
**Future Improvements**
A following patch proposes to improve the speed of the cylinder, cone,
and sphere primitives: D10730. Additional possible future improvements
would be adding subdivisions to the cube node and rings to the cone
and cylinder nodes.
