inline

Construct a full list of patches. All patches have the same basis. For npatches, the lengths of each array should be

  • , , ,
    npatches (i.e. one for each patch)

  • One for each vertex in each patch. That is sum(nu*nv)

  • One for each patch. There is currently no way to specify an attribute per-face for each patch in the patch mesh. You can use a collection of GT_PrimPatch objects if you need this behaviour.

  • A single value
