Dynamic local area lights provide better realism compared with traditional artificial lights, which have been increasing in real-time graphic applications. This paper addresses the problem of real-time direct lighting under dynamic local area lighting by subdividing the original complex area lights into several virtual area lights (VALs) which have uniform radiosity. Then these VALs are used to illuminate the scenes in a closed form solution. Experimental results demonstrate that our method can be run in real-time without precomputation.
