Geometry Nodes: Initial basic curve data support This patch adds initial curve support to geometry nodes. Currently there is only one node available, the "Curve to Mesh" node, T87428. However, the aim of the changes here is larger than just supporting curve data in nodes-- it also uses the opportunity to add better spline data structures, intended to replace the existing curve evaluation code. The curve code in Blender is quite old, and it's generally regarded as some of the messiest, hardest-to-understand code as well. The classes in `BKE_spline.hh` aim to be faster, more extensible, and much more easily understandable. Further explanation can be found in comments in that file. Initial builtin spline attributes are supported-- reading and writing from the `cyclic` and `resolution` attributes works with any of the attribute nodes. Also, only Z-up normal calculation is implemented at the moment, and tilts do not apply yet. **Limitations** - For now, you must bring curves into the node tree with an "Object Info" node. Changes to the curve modifier stack will come later. - Converting to a mesh is necessary to visualize the curve data. Further progress can be tracked in: T87245 Higher level design document: https://wiki.blender.org/wiki/Modules/Physics_Nodes/Projects/EverythingNodes/CurveNodes Differential Revision: https://developer.blender.org/D11091 |
