* @class vtkHyperTreeGridThreshold
|
|
* @brief Extract cells from a hyper tree grid
|
|
* where selected scalar value is within given range.
|
|
*
|
|
*
|
|
* This filter extracts cells from a hyper tree grid that satisfy the
|
|
* following threshold: a cell is considered to be within range if its
|
|
* value for the active scalar is within a specified range (inclusive).
|
|
* The output remains a hyper tree grid.
|
|
* JB Un parametre (JustCreateNewMask=true) permet de ne pas faire
|
|
* le choix de la creation d'un nouveau HTG mais
|
|
* de redefinir juste le masque.
