Note

The nodes PointRange and PointList, provide different ways of defining the patch. Only one of them may be used.
InwardNormalIndex is only meaningful for structured zones.
cgsize_t is determined by the application from which the node is written. For a 32-bit application, cgsize_t will be I4, and I8 for a 64-bit application.
