I haven't found any other interesting light engine than mine,
https://github.com/matiasah/shadows
but there's a small problem: I have to use a polygon shader to paint the penumbra of the shadows, someone told me that using a texture UV trick would solve that out but I'm not really sure, we could keep this until we have something that suits our needings.
