I was searching for soft shadow-mapping here and over the net. But I did not find something easy or fast enough for me. The most interresting thing I found is at this link:
But it is under Directx and I really don’t know how to blur in OpenGL, and I even don’t know if it will be fast enough or if it will be good enough. I mean for closed or far shadows or for little or big objects, simple or complicated ones.
The current shadow-mapping I have is quite good, the shadow limits are also quite soft for long walls. But as soon as the geometry is small and complexe everything becomes a bit uggly.
I really hope to get good advices.
