[vtkusers] How to remove poorly shaped tetrahedra?

[Xiangyi Liu]

Hi all,

For those of you who are familar with generating volume mesh using VTK. I used 
vtkClipVolume to get 3D tetrahedral mesh of a volume. The problem is that a 
considerable portion of the tetrahedra are poorly shaped, in terms that the 
volume of these tetrahedra is really small. I wonder if there is a ready to use 
class that can remove these tetrahedra. I found several classes, but most of 
them are for 2D or 3D surface mesh. 

I wonder if you have gone through this. Any suggestion will be highly 
appreciated!
