Geometry Nodes: SDF Volume nodes milestone 1 Adds initial support for SDF volume creation and manipulation. `SDF volume` is Blender's name of an OpenVDB grid of type Level Set. See the discussion about naming in #91668. The new nodes are: - Mesh to SDF Volume: Converts a mesh to an SDF Volume - Points to SDF Volume: Converts points to an SDF Volume - Mean Filter SDF Volume: Applies a Mean Filter to an SDF - Offset SDF Volume: Applies an offset to an SDF - SDF Volume Sphere: Creates an SDF Volume in the shape of a sphere For now an experimental option `New Volume Nodes` needs to be enabled in Blender preferences for the nodes to be visible. See the current work plan for Volume Nodes in #103248. Pull Request: blender/blender#105090
