Detailed Description

represent the vtkBiDimensionalWidget

The vtkBiDimensionalRepresentation2D is used to represent the bi-dimensional measure in a 2D (overlay) context. This representation consists of two perpendicular lines defined by four vtkHandleRepresentations. The four handles can be independently manipulated consistent with the orthogonal constraint on the lines. (Note: the four points are referred to as Point1, Point2, Point3 and Point4. Point1 and Point2 define the first line; and Point3 and Point4 define the second orthogonal line.)

To create this widget, you click to place the first two points. The third point is mirrored with the fourth point; when you place the third point (which is orthogonal to the lined defined by the first two points), the fourth point is dropped as well. After definition, the four points can be moved (in constrained fashion, preserving orthogonality). Further, the entire widget can be translated by grabbing the center point of the widget; each line can be moved along the other line; and the entire widget can be rotated around its center point.
