/**

* @brief reverse the ordering of polygonal cells and/or vertex normals
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* vtkReverseSense is a filter that reverses the order of polygonal cells
|
||
|
|
* and/or reverses the direction of point and cell normals. Two flags are
|
||
|
|
* used to control these operations. Cell reversal means reversing the order
|
||
|
|
* of indices in the cell connectivity list. Normal reversal means
|
||
|
|
* multiplying the normal vector by -1 (both point and cell normals,
|
||
|
|
* if present).
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* Normals can be operated on only if they are present in the data.
