 Hmm, you could try to import the volume (density/Visualization) into SOPs, scatter points in it and use a Particle Fluid Surface SOP to surface it? Just tested it on a standard smoke setup, and it seems to work fine :) If you need more control, or if you continuous emission of smoke, you could try to advect particles through the volume and surface these the same way.

thanks OLE, but i have a problem with Particle Fluid Surface SOP, it doesn't give me smoothly surface with nice details, if i use filtering, details gone.

and i think scatter point for this work doesn't work very well, they don't give me the true shape of smoke.

Hey ya'll. You can run your density field thru a Volume SDF SOP to generate an SDF from your density field. You can then turn that into a surface using the ISO Offset SOP in Iso Surface/Volume Sample mode, or with the Convert SOP. In the Volume SDF SOP, you can specify at what density threshold the new isocontour is created.
