classical example of rendering 'caustics': points of high intensity where=
light
is reflective/refracted of glossy surfaces or transparent material.
Doesn't work in classical radiance, but will when forward raytracing is a=
dded
to it.
You may want to ask Roland Schregle what the state of his photon map add-=
on
is.
