Implementing fast, ray traced soft shadows in a game engine. About a year ago I published an article on Gamasutra called Practical techniques for ray tracing in games which explained how developers can implement a series of hybrid rendering techniques on PowerVR GR6500 (our ray tracing-capable GPU) to achieve some pretty impressive effects.

Generate a set of M random, uniform shadow rays from P towards disc D. If a ray R intersects anything before hitting L, there is no energy transfer along this path. Otherwise: multiply E/M by a dot product of normal vector N at P and (normalized) R, add the result to the light transferred so far. Repeat for all M rays.

1) pick random positions on the plane. 2) divide the plane to say 10x10 squares and pick the center of each square to send rays. 3) use jittered sampling (1 + 2) of the 3 only choice (2) will produce banding effects. I strongly suggest using (3). it's so much better. stratification is necessary for fast convergance.
