// .NAME vtkReverseSense - reverse the ordering of polygonal cells and/or vertex normals
|
|
// .SECTION Description
|
|
//
|
|
// 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).
|
|
|
|
// .SECTION Caveats
|
|
// Normals can be operated on only if they are present in the data.
