NAME
	  DtFaceGetTextureIndex	- Get the list	of polygonal texture
	  indices for all the polygons in the given shape and group
	  IDs.


     SYNOPSIS
	  #include <Dt.h>


	  int  DtFaceGetTextureVertexIndexByShape( int shapeID,	int groupID, int *count, long **indices);
	  int  DtFaceGetTextureVertexIndexByGroup( int shapeID,	int groupID, int *count, long **indices);


     DESCRIPTION
	  DtFaceGetTextureIndex() returns a list of polygon texture
	  indices via the pointer to the variable indices given	the
	  shape	number,	shapeID, and group number, groupID. The	total
	  number of texture indices into the texture list (the length
	  of the indices array)	is returned via	the pointer to the
	  count	parameter.  Each polygon in the	indices	array is
	  separated by an index	DtEND_OF_FACE (-1). The	number of
	  indices return via the pointer to count includes the
	  DtEND_OF_FACE	separators.  For example, if the first group
	  (groupID = 0)	of the first shape (shapeID = 0) has two
	  triangles, the format	of the texture index array will	be:

	       1 2 3 -1	4 5 6 -1

	  were indices 1, 2, and 3 are for polygon 0 and 4, 5, and 6
	  are for polygon 1.  The parameter count will be set to 8.

	  If no	texture	vertices exist the indices array will be set
	  to NULL.  The	indices	array is an internal buffer.  Do not
	  free or modify the index array.

	  DtFaceGetTextureVertexIndexByShape() returns an array	of
	  indices relative to the texture vertex list for the shape
	  (as returned by DtShapeGetTextureVertices(3W)).
	  DtFaceGetTextureVertexIndexByGroup() returns an array	of
	  indices relative to the texture vertex list for the group
	  (as returned by DtGroupGetTextureVertices(3W)).



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