Function index

Index the input vertex range into a range of indices with the given Indexer. The shared vertices will be put into the given output range. (each vertex is given once)


						
				auto index(VR, VOR, Indexer)
				(
				

				  VR vertexInRange,
				

				  VOR vertexOutRange,
				

				  Indexer indexer = LruIndexer!(ushort, ElementType!VR)(8)
				

				)
				

				if (isInputRange!VR && !isFace!(ElementType!VR) && isOutputRange!(VOR, ElementType!VR) && isIndexer!Indexer && is(ElementType!VR == Indexer.VertexType));
