NAME
	  DtShapeGetVertices - Get a list of vertices for the given
	  shape.


     SYNOPSIS
	  #include <Dt.h>


	  int  DtShapeGetVertices( int shapeID,	int *count, DtVec3f **vertices )


     DESCRIPTION
	  DtShapeGetVertices() returns a vertex	list for the shape
	  indicated by the given shapeID. The number of	vertices is
	  returned in count. A read-only pointer to a list of the
	  vertices is placed in	the variable pointed to	by vertices.
	  This array is	an internal buffer.  Do	not free or modify the
	  vertex array.	 C programmers can access the components of
	  the vertex array as though it	were a simple structure	as
	  follows:

		    typedef struct DtVec3f { float vec[3];};

		    DtVec3f *verts;
		    DtShapeGetVertices(	shapeID, DtVec3f &verts	);
		    /* The first vertex	*/
		    x =	verts[0].vec[0];
		    y =	verts[0].vec[1];
		    z =	verts[0].vec[2];


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