blurring vdbs

float dist = xyzdist(1,@P);

float distremap = fit(dist,ch("near"),ch("far"),0,1);

f@density *= distremap;


This gives a vdb a falloff based on how close it is to the original object's surface.
Stick the VDB into a volume visualisation and then plug that into input 0
Put the original geo into input 2.

Now you can "blur"
