Detailed Description

generate isosurface from structured points

vtkSynchronizedTemplates3D is a 3D implementation of the synchronized template algorithm. Note that vtkContourFilter will automatically use this class when appropriate.

Warning:: This filter is specialized to 3D images (aka volumes).

unsigned long int vtkSynchronizedTemplates3D::GetMTime ( ) [virtual]

Because we delegate to vtkContourValues
