The order of the vertices must be inconsecutive order around the perimeter of the polygon,either clockwise or counterclockwise. No two verticesmay occupy the same location. The polygon sidedefined by the last point and the first point shallcomplete the polygon. The polygon must be a singleplane figure with no sides crossing and no interior holes.Table 20: Occlusion opacityType Code DescriptionTotal T There is no detail in the area of the occlusion.Interference I The occlusion contains interfering texture such as eyelashes, hair or reflection.Partial Light L There is detail in the area of the occlusion that is lighter than the rest of the face or iris.Partial shadow S There is detail in the area of the occlusion that is darker than the rest of the face or iris.May, 2013 DRAFT VERSION UPDATE 2013 Page 95
