In this paper, we present a hybrid algorithm for determining the quantitative invisibility (QI) of scene edges. This is accomplished by drawing the edges and faces of each model using hardware blending to create an ID image. Then a simple counting problem yields the QI of each edge. This method automatically determines which edges must be split due to silhouette occlusion and surface intersection, making this algorithm faster than previous hybrid visibility algorithms for complex scenes. We demonstrate the utility of hybrid QI by presenting a method for removing silhouette degeneracies based on the QI of sihouette edges.
