VTK does not have an adaptive isosurface algorithm. You can increase the dimensions of your sampling and then apply one of several decimation algorithms to reduce the polygons. The decimation algorithms will keep more polygons in areas with more detail.<div>

curvature is high so that the surface is more accurately represented.<br>
Does the Sinc filter do that? If not, is there something like [0] or<br>
[1] in VTK?<br>
