// .NAME vtkAppendFilter - appends one or more datasets together into a single unstructured grid
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkAppendFilter is a filter that appends one of more datasets into a single
|
||
|
|
// unstructured grid. All geometry is extracted and appended, but point
|
||
|
|
// attributes (i.e., scalars, vectors, normals, field data, etc.) are extracted
|
||
|
|
// and appended only if all datasets have the point attributes available.
|
||
|
|
// (For example, if one dataset has scalars but another does not, scalars will
|
||
|
|
// not be appended.)
