Rendering a deforming object in animation including: defining a deforming object surface angle; identifying a normal vector discontinuity point using the deforming object surface angle; defining front part and back part of the deforming object with reference to the normal vector discontinuity point; dividing the front part of the deforming object into zones based on the deforming object surface angle; dividing the back part of the deforming object into zones based on the deforming object surface angle; and rendering each zone.
