Yes, I tried with subdivision and the following values:

	#declare isoSegs = <32,32,32>;
	#declare Depth = 3;

The edges are still too rough. I've attached the result. I'm not good 
with modifying meshes by hand, so I will forego doing that. I will 
instead wait for the true isosurface to finish rendering.

There's one thing I'm worried about though. The place where the 
isosurface meets the cylinder showed holes or gaps last time I rendered 
a test image. But hopefully decreasing "accuracy" will clear up the issue.
