NAME
	  DtPolygonMtlGetName -	Get the	name of	the material assigned
	  to the given polygon.


     SYNOPSIS
	  #include <Dt.h>

	  int  DtPolygonMtlGetName( int	shapeID, int groupID, int index, char **name )

     DESCRIPTION
	  DtPolygonMtlGetName()	returns	the name of the	material, via
	  a pointer to the variable name, for the given	polygon	index
	  in the shape,	shapeID, and group, groupID. The name array is
	  an internal buffer.  Do not free or modify the name.


     OPENMODEL IMPLEMENTATION
	  The OpenModel	implementation of Dt converts per-poly shaders
	  in OpenModel into multiple groups within a single shape. All
	  polygons of a	group in Dt will correspond to polygons	in an
	  Alias	model sharing a	single shader. For this	reason,	all
	  polygons in a	particular shape and group will	share the same
	  material name. The index parameter is	ignored.


     DIAGNOSTICS
	  DtPolygonMtlGetName()	returns	one on success and zero	on
	  failure.
