A hot melt glue gun includes a barrel, an inner tube, and an outer tube. The invention includes communication destination matrixes used for project source and destination vertex arrays of, source and destination objects from an original space to an ortho-normal space. A line equation common scalefactor value is determined from the first and second common scalefactor values. These polymers have the processability of chromium-based resins, but with improved stiffness and stress crack resistance, and can be used in blow molding and other end-use applications.
