Investigation into the feasibility of shadow generation on mobile graphic cards

Current commodity graphic cards are capable of generating real-time realistic shadows in 3D scenes. This is possible as they are highly optimized for vector computation due to their highly pipelined architecture. This speed comes at a power cost that is rarely considered. This study investigates the feasibility of generating shadows in real-time but on mobile graphics cards. We see that it is possible to generate shadows in real-time but using cheap algorithms.
