measure the bi-dimensional lengths of an object
<p>
The <a class="el" href="a00165.html" title="measure the bi-dimensional lengths of an object">vtkBiDimensionalWidget</a> is used to measure the bi-dimensional length of an object. The bi-dimensional measure is defined by two finite, orthogonal lines that intersect within the finite extent of both lines. The lengths of these two lines gives the bi-dimensional measure. Each line is defined by two handle widgets at the end points of each line.<p>
The orthognal constraint on the two lines limits how the four end points can be positioned. The first two points can be placed arbitrarily to define the first line (similar to <a class="el" href="a00430.html" title="measure the distance between two points">vtkDistanceWidget</a>). The placement of the third point is limited by the finite extent of the first line. As the third point is placed, the fourth point is placed on the opposite side of the first line. Once the third point is placed, the second line is defined since the fourth point is defined at the same time, but the fourth point can be moved along the second line (i.e., maintaining the orthogonal relationship between the two lines). Onced defined, any of the four points can be moved along their constraint lines. Also, each line can be translated along the other line (in an orthogonal direction), and the whole bi-dimensional widget can be rotated about its center point (see the description of the event bindings). Finally, selecting the point where the two orthogonal axes intersect, the entire widget can be translated in any direction.<p>
Placement of any point results in a special PlacePointEvent invocation so that special operations may be performed to reposition the point. Motion of any point, moving the lines, or rotating the widget cause InteractionEvents to be invoked. Note that the widget has two fundamental modes: a define mode (when initially placing the points) and a manipulate mode (after the points are placed). Line translation and rotation are only possible in manipulate mode.<p>
To use this widget, specify an instance of <a class="el" href="a00165.html" title="measure the bi-dimensional lengths of an object">vtkBiDimensionalWidget</a> and a representation (e.g., <a class="el" href="a00164.html" title="represent the vtkBiDimensionalWidget">vtkBiDimensionalRepresentation2D</a>). The widget is implemented using four instances of <a class="el" href="a00679.html" title="a general widget for moving handles">vtkHandleWidget</a> which are used to position the end points of the two intersecting lines. The representations for these handle widgets are provided by the <a class="el" href="a00164.html" title="represent the vtkBiDimensionalWidget">vtkBiDimensionalRepresentation2D</a> class.<p>
<dl class="user" compact><dt><b>Event Bindings:</b></dt><dd>By default, the widget responds to the following VTK events (i.e., it watches the <a class="el" href="a01491.html" title="platform-independent render window interaction including picking and frame rate control...">vtkRenderWindowInteractor</a> for these events): <pre>
LeftButtonPressEvent - define a point or manipulate a handle, line,
perform rotation or translate the widget.
MouseMoveEvent - position the points, move a line, rotate or translate the widget
LeftButtonReleaseEvent - release the selected handle and end interaction
