Description

The vdb_print binary is missing support for VDB Point grids. This would be super useful. Some recommended functionality:

  • total/active/inactive point count
  • attribute name, type, uniform, index, flags, compression information
  • group name and count information
  • whether the descriptor is shared (option to print out all descriptors which differ?)

I suggest that this is only implemented for ABI=6 and above as there are some new virtual functions that will make this easier.

Contributor guide

Research direction
Investigate the vdb print source code, understand the current grid printing logic, and extend it to handle VDB Point grids, focusing on ABI 6+ features like new virtual functions for point attribute and group information.
