I'm looking to implement shadows soon using shadow maps, I found a good paper that describes how to eliminate the usual problems of perspective aliasing however I've been trying to find any info on how to combat the problems of projection aliasing, without resorting to increasing the shadow map resolution.
For those not familiar projection aliasing is caused when the camera and the light are facing each other at a distance. i.e. what the light sees as being small (hence low resolution) the camera sees as being large and you get projection aliasing.
Has anyone here managed good shadows using shadow maps if so I'd appreciate any feedback you might have.
