// .NAME vtkSynchronizedTemplates2D - generate isoline(s) from a structured points set
|
|
// .SECTION Description
|
|
// vtkSynchronizedTemplates2D is a 2D implementation of the synchronized
|
|
// template algorithm. Note that vtkContourFilter will automatically
|
|
// use this class when appropriate.
|
|
|
|
// .SECTION Caveats
|
|
// This filter is specialized to 2D images.
