|
|
* @brief represent the vtkResliceCursorWidget
|
|
*
|
|
* This class provides a representation for the reslice cursor widget. It
|
|
* consists of two cross sectional hairs, with an optional thickness. The
|
|
* hairs may have a hole in the center. These may be translated or rotated
|
|
* independent of each other in the view. The result is used to reslice
|
|
* the data along these cross sections. This allows the user to perform
|
|
* multi-planar thin or thick reformat of the data on an image view, rather
|
|
* than a 3D view.
