1. A computer-implemented method comprising: accessing a three-dimensional graphical object that represents a game element of a wagering game, wherein the three-dimensional graphical object is controlled via an application running on a wagering game machine during a wagering game session, wherein the three-dimensional graphical object comprises a plurality of degenerate polygons which form a first geometric structure for the three-dimensional graphical object; and morphing the three-dimensional graphical object from the first geometric structure into a second geometric structure via manipulation of the plurality of degenerate polygons, wherein the second geometric structure is structurally distinct from the first geometric structure.
