[ITK] [ITK-users] Isosurface extraction with ITK

Hi all,
I'm trying to perform isosurface extraction from a continuous map using
ITK (no VTK). The closest match I've found is the BinaryMask3DMeshSource
which performs the Marching Cubes on a binary mask.
Unfortunately this requires thresholding the input before meshing, which
results in rough edges in the output mesh. VTK's marching cube filter
allows setting a floating-point isosurface value and the resulting
meshes are noticeably smoother.
Is there a better solution to this problem using ITK only? Is there any
particular reason why the marching cubes algorithm is implemented
differently in ITK and VTK?
Thanks!
joel
