Subject: Shadows ?
Sender: [e-mail]
Precedence: bulk

isn't there some shadow mapping algorithm out there in the
Siggraph papers ( or somewhere :-) ) which allows a
renderer to calculate the shadow casting *once* for a scene,
then, if *no* movement occurs *except* for the camera moving,
it doesn't need to recalculate the shadows for subsequent
renderings ? i'm thinking in terms of an architectural
walkthru, where everything stays static except the camera...
( i am not talking about radiosity, which i realize can
also get this effect plus a plethora of other cool stuff
at prohibitive render times :-) )
