Due to the high complexity of the\nproblem for highly complex scenes, a stochastic\nvariation of Jacobi iteration is developed which\nconverges stochastically to the correct solution.\nThe new method, called Stochastic Ray Method, is a\nsignificant improvement of Stochastic Radiosity. A\nlarge number of independent rays is chosen\nstochastically by importance sampling of the\npatches according to their power after the previous\niteration step. They all carry an equal amount of\npower into random directions, thereby representing\ntogether the total energy interreflection of the\nentire environment in a stochastic manner.\nAssuming a correctly distributed initial solution,\nwhich can be reached easily, the iteration\nprocess converges quickly and reduces the error\nin the result faster than other stochastic\nradiosity approaches.
