Hi,
After studying some materials on metaballs, I found it really quite complicated
to convert metaballs to b-rep form. Although we can deduce the accurate
equation of the surfaces (the accumulated value equals to the threshold), it's
hard to represent them in NURBS. But as far as I'm concerned, if we can convert
metaballs to brep, it would be wonderful as metaball is also a useful solid
representation. But the conversion, I think, is not easy. I could not find any
simple approach.
Could someone please give me some advice on this? How to implement the
conversion, or, is it quite necessary to implement it now?
Cheers!
Wu
