[vtkusers] isosurfaces..??

[Manan Syal]

Hello all...

    what algorithm does vtk implement in order to extract isosurfaces
and render them ? is marching cubes the algorithm used? if so, isn't it
true that this algorithm is not the most optimal, and there have been
many other algorithms that have been proposed to reduce the
computational complexities associated with isosurface extraction?
Please tell me what algorithm is used by vtk for this purpose, and also
how optimum have u found using it?

Thank you in  advance,

Manan Syal.
