As Mike explained, the direct way is far from optimal.

An alternative method, turn your object into a set of 16 bit gray-scale 
TIFF slices.  Then use a tool like ImageJ http://rsb.info.nih.gov/ij/ to 
blurr the stack. Convert the whole stack into a df3-file and render.

Sadly ImageJ does not read/write df3-files and I don't understand the Java 
to make the right plugin for that ... ImageJ is a vwery usefull tool for 
manipulating 3D-datasets.
