// .NAME vtkStructuredGridVolumeRepresentation - representation for showing
|
|
// vtkStructuredGrid datasets as volumes.
|
|
// .SECTION Description
|
|
// vtkStructuredGridVolumeRepresentation is a representation for volume
|
|
// rendering vtkStructuredGrid datasets with one caveat: it assumes that the
|
|
// structured grid is not "curved" i.e. bounding boxes of non-intersecting
|
|
// extents don't intersect (or intersect negligibly). This is the default (and
|
|
// faster) method. Alternatively, one can set UseDataParititions to
|
|
// off and the representation will simply reply on the view to build the sorting
|
|
// order using the unstructured grid. In which case, however data will be
|
|
// transferred among processing.
