Geometry Nodes: Add modifier disabled check |
Revision 94572a4 by Jacques Lucke (attribute-accessor, geometry-nodes, geometry-nodes-active-modifier-drawing, geometry-nodes-attribute-nodes, geometry-nodes-deduplicate-float-math, geometry-nodes-distribute-points, geometry-nodes-mix-attributes, geometry-nodes-point-separate-node, temp-geometry-nodes-distribute-points-cleanup) November 12, 2020, 15:58 (GMT) |
Geometry Nodes: use density attribute name instead of index as node input This implements a workaround for the issue that (for historical reasons) the names of vertex groups are stored on the object while the actual vertex group data is stored on the mesh. The solution is to copy the vertex group names from the object into the `MeshComponent` so that the information is not lost, when the object cannot be accessed. |
Revision bc2230d by Jacques Lucke (attribute-accessor, geometry-nodes, geometry-nodes-active-modifier-drawing, geometry-nodes-attribute-nodes, geometry-nodes-deduplicate-float-math, geometry-nodes-distribute-points, geometry-nodes-mix-attributes, geometry-nodes-point-separate-node, temp-geometry-nodes-distribute-points-cleanup) November 12, 2020, 15:31 (GMT) |
Geometry Nodes: cleanup geometry node interface Previously, the execution function of a geometry node has three parameters. Now it has only one. This makes it easier to pass more information to the execution function, that might only be used by a few nodes, because we don't have to add more parameters that are unused in most cases. |

Revision 770bcfa by Jacques Lucke (attribute-accessor, geometry-nodes, geometry-nodes-active-modifier-drawing, geometry-nodes-attribute-nodes, geometry-nodes-deduplicate-float-math, geometry-nodes-distribute-points, geometry-nodes-mix-attributes, geometry-nodes-point-separate-node, temp-geometry-nodes-distribute-points-cleanup) November 12, 2020, 12:24 (GMT) |
Geometry Nodes: improve point distribute node * Support vertex weights to control density. * O(n) performance instead of O(n^2). * More stable when density weights are changed. The vertex group has to be specified using an index for now. This is a technical limitation that will resolved a bit later. |

Geometry Nodes: support geometry components in depsgraph object iterator Objects can evaluate to a geometry set instead of a single ID (only point cloud objects for now). In the depsgraph object iterator, those geometry components are expanded into temporary objects. It's important to note that instanced objects can also contain geometry components. Therefore, they have to be split up into multiple objects as well in some cases. At a high level the iterator works like so: ``` for object in depsgraph: for component in object: yield object_from_component(component) for dupli in make_duplis_list(object): for component in dupli: yield object_from_component(component) ``` DEG_iterator_objects_next has been cleaned up, to make this structure a bit more apparent. |

Geometry Nodes: better handle link cycles |

Geometry Nodes: use GeometrySet when evaluating pointcloud modifiers This changes the signature of the modifyPointCloud function. I'm doing that instead of making a new callback, because it requires changes to significantly fewer files. Eventually it would be good combine modifyMesh, modifyHair, modifyPointCloud and modifyVolume into one modifyGeometrySet. I temporarily disabled the displacement only modifiers for point clouds. Support can be added back a bit later. I assume those have not been used anywhere anyway. The output of point cloud modifiers can not only be another point cloud, but also a mesh and/or some instances. I added a new geometry_set_eval field to Object_Runtime. For point cloud objects, the final geometry is now referenced by that pointer instead of data_eval. The data_eval field is still initialized after modifier evaluation to make some other code happy. The evaluated geometry set is not yet passed to the renderer, so a point cloud is currently rendered empty. |

Geometry Nodes: initial Object Info node This node takes an object as input and outputs its location, rotation, scale and geometry. Right now the loc/rot/scale are extracted from the objects `obmat`. The geometry is just the mesh in the local space of the source object. We will likely need some more control over space transformations using enums in the node, but those can be added a bit later. |

Geometry Nodes: initial object socket support The fundamental difference between object sockets and the other existing data sockets is that an object is an ID data block. Changing the value of an object socket also changes the depsgraph. The modifier has to analyse the node tree to figure out which other objects it depends on. Currently, this is done very simply by just looping over all sockets and collecting the objects. In the future this can be improved by also figuring out what components of an object are needed. Instead of passing object pointers around in the node tree, we actually use a handle. This handle is just a number internally that identifies a specific object. The conversion between handles and object pointers is done using a map that is provided by the modifier. This approach has a couple of benefits. It protects us a bit from passing around pointers that are not known to the modifier and therefore are not in the depsgraph. Furthermore, the object pointer can change while the handle stays the same. This is not important right now, but is not unlikely to become useful in the future. The API for how nodes access object pointers is not ideal yet and will be improved in the future. |
