Add three nodes to the currently experimental volume grid nodes: - **Mesh to Density Grid** - **Mesh to SDF Grid** - **Points to SDF Grid** These nodes are just wrappers over basic OpenVDB utilities. The difference from existing volume nodes is that they output a grid directly instead of a geometry set. See the design here: https://devtalk.blender.org/t/volumes-in-geometry-nodes-proposal/31917 Pull Request: https://projects.blender.org/blender/blender/pulls/118761
