Geometry Nodes: Curve and mesh topology access nodes This patch contains an initial set of nodes to access basic mesh topology information, as explored in T100020. The nodes allow six direct topology mappings for meshes: - **Corner -> Face** The face a corner is in, the index in the face - **Vertex -> Edge** Choose an edge attached to the vertex - **Vertex -> Corner** Choose a corner attached to the vertex - **Corner -> Edge** The next and previous edge at each face corner - **Corner -> Vertex** The vertex associated with a corner - **Corner -> Corner** Offset a corner index within a face And two new topology mappings for curves: - **Curve -> Points** Choose a point within a curve - **Point -> Curve** The curve a point is in, the index in the curve The idea is that some of the 16 possible mesh mappings are more important, and that this is a useful set of nodes to start exploring this area. For mappings with an arbitrary number of connections, we must sort them and use an index to choose a single element, because geometry nodes does not support list fields. Note that the sort index has repeating behavior as it goes over the "Total" number of connections, and negative sort indices choose from the end. Currently which of the "start" elements is used is determined by the field context, so the "Field at Index" and "Interpolate Domain" nodes will be quite important. Also, currently the "Sort Index" inputs are clamped to the number of connections. One important feature that isn't implemented here is using the winding order for the output elements. This can be a separate mode for some of these nodes. It will be optional because of the performance impact. There are several todos for separate commits after this: - Rename "Control Point Neighbors" to be consistent with this naming - Version away the "Vertex Neighbors" node which is fully redundant now - Implement a special case for when no weights are used for performance - De-duplicating some of the sorting logic between the nodes - Improve performance and memory use of topology mappings - Look into caching some of the mappings on meshes Differential Revision: https://developer.blender.org/D16029

Geometry Nodes: new Bake node This adds a new `Bake` node which allows saving and loading intermediate geometries. Typical use cases we want address with this currently are: * Bake some data for use with a render engine. * Bake parts of the node tree explicitly for better performance. For now, the format that is written to disk is not considered to be an import/export format. It's not guaranteed that data written with one Blender version can be read by another Blender version. For that it's better to use proper interchange formats. Better support for those will be added eventually as well. We also plan an `Import Bake` node that allows reading the blender-specific baked data independent of the Bake node and at different frames. The baking works very similar to the baking in the simulation zone (UI and implementation wise). Major differences are: * The Bake node has a `Bake Still` and `Bake Animation` mode. * The Bake node doesn't do automatic caching. Implementation details: * Refactored how we create the Python operators for moving socket items so that it also makes sense for non-zones. * The `ModifierCache` stores an independent map of `SimulationNodeCache` and `BakeNodeCache`, but both share a common data structure for the actually baked data. * For baking, the `Bake` node is added as a side-effect-node in the modifier. This will make sure that the node is baked even if it's currently not connected to the output. * Had to add a new `DEG_id_tag_update_for_side_effect_request` function that is used during baking. It's necessary because I want to evaluate the object again even though none of its inputs changed. The reevaluation is necessary to create the baked data. Using `DEG_id_tag_update` technically works as well, but has the problem that it also uses the `DEG_UPDATE_SOURCE_USER_EDIT` flag which (rightly) invalidates simulation caches which shouldn't happen here. * Slightly refactored the timeline drawing so that it can also show the baked ranges of Bake nodes. It does not show anything for baked nodes with a in Still mode though. * The bake operator is refactored to bake a list of `NodeBakeRequest` which makes the code easier to follow compared to the previous nested `ObjectBakeData > ModifierBakeData > NodeBakeData` data structure. * The bake operators are disabled when the .blend file is not yet saved. This is technically only necessary when the bake path depends on the .blend file path but seems ok to force the user anyway (otherwise the bake path may be lost as well if it's set explicitly). * The same operators are used to bake and delete single bakes in `Bake` nodes and `Simulation Zones`. On top of that, there are separate operators of baking and deleting all simulation bakes (those ignore bake nodes). * The `Bake` node remembers which inputs have been fields and thus may be baked as attributes. For that it uses an `Is Attribute` flag on the socket item. This is needed because the baked data may still contain attribute data, even if the inputs to the bake node are disconnected. * Similar to simulation zones, the behavior of `Bake` nodes is passed into the geometry nodes evaluation from the outside (from the modifier only currently). This is done by providing the new `GeoNodesBakeParams` in `GeoNodesCallData` when executing geometry nodes. Next Steps (mostly because they also involve simulations): * Visualize nodes that have not been evaluated in the last evaluation. * Fix issue with seemingly loosing baked data after undo. * Improve error handling when baked data is not found. * Show bake node in link drag search. * Higher level tools for managing bakes.

Geometry Nodes: Curve and mesh topology access nodes This patch contains an initial set of nodes to access basic mesh topology information, as explored in T100020. The nodes allow six direct topology mappings for meshes: - **Corner -> Face** The face a corner is in, the index in the face - **Vertex -> Edge** Choose an edge attached to the vertex - **Vertex -> Corner** Choose a corner attached to the vertex - **Corner -> Edge** The next and previous edge at each face corner - **Corner -> Vertex** The vertex associated with a corner - **Corner -> Corner** Offset a corner index within a face And two new topology mappings for curves: - **Curve -> Points** Choose a point within a curve - **Point -> Curve** The curve a point is in, the index in the curve The idea is that some of the 16 possible mesh mappings are more important, and that this is a useful set of nodes to start exploring this area. For mappings with an arbitrary number of connections, we must sort them and use an index to choose a single element, because geometry nodes does not support list fields. Note that the sort index has repeating behavior as it goes over the "Total" number of connections, and negative sort indices choose from the end. Currently which of the "start" elements is used is determined by the field context, so the "Field at Index" and "Interpolate Domain" nodes will be quite important. Also, currently the "Sort Index" inputs are clamped to the number of connections. One important feature that isn't implemented here is using the winding order for the output elements. This can be a separate mode for some of these nodes. It will be optional because of the performance impact. There are several todos for separate commits after this: - Rename "Control Point Neighbors" to be consistent with this naming - Version away the "Vertex Neighbors" node which is fully redundant now - Implement a special case for when no weights are used for performance - De-duplicating some of the sorting logic between the nodes - Improve performance and memory use of topology mappings - Look into caching some of the mappings on meshes Differential Revision: https://developer.blender.org/D16029

Geometry Nodes: add simulation support This adds support for building simulations with geometry nodes. A new `Simulation Input` and `Simulation Output` node allow maintaining a simulation state across multiple frames. Together these two nodes form a `simulation zone` which contains all the nodes that update the simulation state from one frame to the next. A new simulation zone can be added via the menu (`Simulation > Simulation Zone`) or with the node add search. The simulation state contains a geometry by default. However, it is possible to add multiple geometry sockets as well as other socket types. Currently, field inputs are evaluated and stored for the preceding geometry socket in the order that the sockets are shown. Simulation state items can be added by linking one of the empty sockets to something else. In the sidebar, there is a new panel that allows adding, removing and reordering these sockets. The simulation nodes behave as follows: * On the first frame, the inputs of the `Simulation Input` node are evaluated to initialize the simulation state. In later frames these sockets are not evaluated anymore. The `Delta Time` at the first frame is zero, but the simulation zone is still evaluated. * On every next frame, the `Simulation Input` node outputs the simulation state of the previous frame. Nodes in the simulation zone can edit that data in arbitrary ways, also taking into account the `Delta Time`. The new simulation state has to be passed to the `Simulation Output` node where it is cached and forwarded. * On a frame that is already cached or baked, the nodes in the simulation zone are not evaluated, because the `Simulation Output` node can return the previously cached data directly. It is not allowed to connect sockets from inside the simulation zone to the outside without going through the `Simulation Output` node. This is a necessary restriction to make caching and sub-frame interpolation work. Links can go into the simulation zone without problems though. Anonymous attributes are not propagated by the simulation nodes unless they are explicitly stored in the simulation state. This is unfortunate, but currently there is no practical and reliable alternative. The core problem is detecting which anonymous attributes will be required for the simulation and afterwards. While we can detect this for the current evaluation, we can't look into the future in time to see what data will be necessary. We intend to make it easier to explicitly pass data through a simulation in the future, even if the simulation is in a nested node group. There is a new `Simulation Nodes` panel in the physics tab in the properties editor. It allows baking all simulation zones on the selected objects. The baking options are intentially kept at a minimum for this MVP. More features for simulation baking as well as baking in general can be expected to be added separately. All baked data is stored on disk in a folder next to the .blend file. #106937 describes how baking is implemented in more detail. Volumes can not be baked yet and materials are lost during baking for now. Packing the baked data into the .blend file is not yet supported. The timeline indicates which frames are currently cached, baked or cached but invalidated by user-changes. Simulation input and output nodes are internally linked together by their `bNode.identifier` which stays the same even if the node name changes. They are generally added and removed together. However, there are still cases where "dangling" simulation nodes can be created currently. Those generally don't cause harm, but would be nice to avoid this in more cases in the future.

Geometry Nodes: Menu Switch Node This patch adds support for _Menu Switch_ nodes and enum definitions in node trees more generally. The design is based on the outcome of the [2022 Nodes Workshop](https://code.blender.org/2022/11/geometry-nodes-workshop-2022/#menu-switch). The _Menu Switch_ node is an advanced version of the _Switch_ node which has a customizable **menu input socket** instead of a simple boolean. The _items_ of this menu are owned by the node itself. Each item has a name and description and unique identifier that is used internally. A menu _socket_ represents a concrete value out of the list of items. To enable selection of an enum value for unconnected sockets the menu is presented as a dropdown list like built-in enums. When the socket is connected a shared pointer to the enum definition is propagated along links and stored in socket default values. This allows node groups to expose a menu from an internal menu switch as a parameter. The enum definition is a runtime copy of the enum items in DNA that allows sharing. A menu socket can have multiple connections, which can lead to ambiguity. If two or more different menu source nodes are connected to a socket it gets marked as _undefined_. Any connection to an undefined menu socket is invalid as a hint to users that there is a problem. A warning/error is also shown on nodes with undefined menu sockets. At runtime the value of a menu socket is the simple integer identifier. This can also be a field in geometry nodes. The identifier is unique within each enum definition, and it is persistent even when items are added, removed, or changed. Changing the name of an item does not affect the internal identifier, so users can rename enum items without breaking existing input values. This also persists if, for example, a linked node group is temporarily unavailable. Pull Request: https://projects.blender.org/blender/blender/pulls/113445

Geometry Nodes: new Repeat Zone This adds support for running a set of nodes repeatedly. The number of iterations can be controlled dynamically as an input of the repeat zone. The repeat zone can be added in via the search or from the Add > Utilities menu. The main use case is to replace long repetitive node chains with a more flexible alternative. Technically, repeat zones can also be used for many other use cases. However, due to their serial nature, performance is very sub-optimal when they are used to solve problems that could be processed in parallel. Better solutions for such use cases will be worked on separately. Repeat zones are similar to simulation zones. The major difference is that they have no concept of time and are always evaluated entirely in the current frame, while in simulations only a single iteration is evaluated per frame. Stopping the repetition early using a dynamic condition is not yet supported. "Break" functionality can be implemented manually using Switch nodes in the loop for now. It's likely that this functionality will be built into the repeat zone in the future. For now, things are kept more simple. Remaining Todos after this first version: * Improve socket inspection and viewer node support. Currently, only the first iteration is taken into account for socket inspection and the viewer. * Make loop evaluation more lazy. Currently, the evaluation is eager, meaning that it evaluates some nodes even though their output may not be required. Pull Request: https://projects.blender.org/blender/blender/pulls/109164

Geometry Nodes: add simulation support This adds support for building simulations with geometry nodes. A new `Simulation Input` and `Simulation Output` node allow maintaining a simulation state across multiple frames. Together these two nodes form a `simulation zone` which contains all the nodes that update the simulation state from one frame to the next. A new simulation zone can be added via the menu (`Simulation > Simulation Zone`) or with the node add search. The simulation state contains a geometry by default. However, it is possible to add multiple geometry sockets as well as other socket types. Currently, field inputs are evaluated and stored for the preceding geometry socket in the order that the sockets are shown. Simulation state items can be added by linking one of the empty sockets to something else. In the sidebar, there is a new panel that allows adding, removing and reordering these sockets. The simulation nodes behave as follows: * On the first frame, the inputs of the `Simulation Input` node are evaluated to initialize the simulation state. In later frames these sockets are not evaluated anymore. The `Delta Time` at the first frame is zero, but the simulation zone is still evaluated. * On every next frame, the `Simulation Input` node outputs the simulation state of the previous frame. Nodes in the simulation zone can edit that data in arbitrary ways, also taking into account the `Delta Time`. The new simulation state has to be passed to the `Simulation Output` node where it is cached and forwarded. * On a frame that is already cached or baked, the nodes in the simulation zone are not evaluated, because the `Simulation Output` node can return the previously cached data directly. It is not allowed to connect sockets from inside the simulation zone to the outside without going through the `Simulation Output` node. This is a necessary restriction to make caching and sub-frame interpolation work. Links can go into the simulation zone without problems though. Anonymous attributes are not propagated by the simulation nodes unless they are explicitly stored in the simulation state. This is unfortunate, but currently there is no practical and reliable alternative. The core problem is detecting which anonymous attributes will be required for the simulation and afterwards. While we can detect this for the current evaluation, we can't look into the future in time to see what data will be necessary. We intend to make it easier to explicitly pass data through a simulation in the future, even if the simulation is in a nested node group. There is a new `Simulation Nodes` panel in the physics tab in the properties editor. It allows baking all simulation zones on the selected objects. The baking options are intentially kept at a minimum for this MVP. More features for simulation baking as well as baking in general can be expected to be added separately. All baked data is stored on disk in a folder next to the .blend file. #106937 describes how baking is implemented in more detail. Volumes can not be baked yet and materials are lost during baking for now. Packing the baked data into the .blend file is not yet supported. The timeline indicates which frames are currently cached, baked or cached but invalidated by user-changes. Simulation input and output nodes are internally linked together by their `bNode.identifier` which stays the same even if the node name changes. They are generally added and removed together. However, there are still cases where "dangling" simulation nodes can be created currently. Those generally don't cause harm, but would be nice to avoid this in more cases in the future.

Geometry Nodes: Curve and mesh topology access nodes This patch contains an initial set of nodes to access basic mesh topology information, as explored in T100020. The nodes allow six direct topology mappings for meshes: - **Corner -> Face** The face a corner is in, the index in the face - **Vertex -> Edge** Choose an edge attached to the vertex - **Vertex -> Corner** Choose a corner attached to the vertex - **Corner -> Edge** The next and previous edge at each face corner - **Corner -> Vertex** The vertex associated with a corner - **Corner -> Corner** Offset a corner index within a face And two new topology mappings for curves: - **Curve -> Points** Choose a point within a curve - **Point -> Curve** The curve a point is in, the index in the curve The idea is that some of the 16 possible mesh mappings are more important, and that this is a useful set of nodes to start exploring this area. For mappings with an arbitrary number of connections, we must sort them and use an index to choose a single element, because geometry nodes does not support list fields. Note that the sort index has repeating behavior as it goes over the "Total" number of connections, and negative sort indices choose from the end. Currently which of the "start" elements is used is determined by the field context, so the "Field at Index" and "Interpolate Domain" nodes will be quite important. Also, currently the "Sort Index" inputs are clamped to the number of connections. One important feature that isn't implemented here is using the winding order for the output elements. This can be a separate mode for some of these nodes. It will be optional because of the performance impact. There are several todos for separate commits after this: - Rename "Control Point Neighbors" to be consistent with this naming - Version away the "Vertex Neighbors" node which is fully redundant now - Implement a special case for when no weights are used for performance - De-duplicating some of the sorting logic between the nodes - Improve performance and memory use of topology mappings - Look into caching some of the mappings on meshes Differential Revision: https://developer.blender.org/D16029
