Detailed Description

GridAccessor manages access to a GEO_PrimVDB's grid.

In keeping with OpenVDB library conventions, the grid is stored internally by shared pointer. However, grid objects are never shared among primitives, though their voxel data (i.e., their trees) may be shared.

Among other things, GridAccessor

• ensures that each primitive's transform and metadata are unique (i.e., not shared with anyone else)
• allows primitives to share voxel data but, via makeGridUnique(), provides a way to break the connection
• ensures that the primitive's transform and the grid's transform are in sync (specifically, the translation component, which is stored independently as a vertex offset).
