soft shadows!

Hi, all,
     I've attached my image with this mail. I was just
struggling for the soft shadows. This is my parameters for rpict:
     rpict -vf default.vp -ps 1 -aa .08 -ab 2 -ad 512 -as 256 -ar 128
-dj .6 -ds .1 -x 12288 -y 9216 scene.oct > scene.pic
I made such a large image to get 12 times oversample. I then filter
it down. This is for pfilt:
     pfilt -e .4 -r .7 -x 1024 -y 768 scene.pic > scene_filt.pic
Even so, I still get the image like that. I'm really confused. How
to get a satisfying result?

cheers,

    Alex

Try

rpict ... -ds .05 -dj .2 or 0.15 -ar 5000 -ps 1 -ad 512 -as 256

I was going to suggest -dj 0.9 and compile with the -DMC option.

You shouldn't be seeing these lines. I expect the -dj .6 combined with -ds .1 are causing aiming failures that are resulting in these weird arguments. I concur with Mark's suggestion, though the -DMC recompilation is a bit drastic. You might simply try -ds .4 -dj .4 first to see if that fixes it.
