VTK data export
==================================

These functions sample the OpenVCAD tree and write VTK XML data files for use in
ParaView or other VTK-based tools. They are **not** bitmap or video exports.

Iso-surfaces are written as ``.vtp`` (VTK XML polydata). Full volumes are written
as ``.vti`` (VTK XML image data).
