LOD based Real Time Shadow Generation for Subdivison Surfaces

Mustafa, S. Fawad, Member, IACSIT

Abstract—Shadow generation in gaming and animation industries has attracted many researchers to achieve the best possible outcome from their concepts for complex scenes. Realism to the Scene is only possible if we have accurate shadows with complex objects. For this reason Subdivision surfaces were introduced to describe a surface using a polygonal model with fine smoothness. Here, we discuss an approach to efficiently render shadows for subdivision surfaces by introducing the Level-of-Details and visibility function. In this way we can achieve fast and robust scene rendering with multiple subdivision models. In this paper we have proposed an improvement on rendering rate of shadow volume technique for subdivision surfaces using graphic hardware.

Index Terms—shadow volume, geometric images, Level-of-Details, graphics hardware
