Picks props behind a selection rectangle on a viewport.
<p>
The <a class="el" href="a00123.html" title="Picks props behind a selection rectangle on a viewport.">vtkAreaPicker</a> picks all vtkProp3Ds that lie behind the screen space rectangle from x0,y0 and x1,y1. The selection is based upon the bounding box of the prop and is thus not exact.<p>
Like <a class="el" href="a01212.html" title="superclass for 3D geometric pickers (uses ray cast)">vtkPicker</a>, a pick results in a list of Prop3Ds because many props may lie within the pick frustum. You can also get an AssemblyPath, which in this case is defined to be the path to the one particular prop in the Prop3D list that lies nearest to the near plane.<p>
This picker also returns the selection frustum, defined as either a <a class="el" href="a01226.html" title="implicit function for convex set of planes">vtkPlanes</a>, or a set of eight corner vertices in world space. The <a class="el" href="a01226.html" title="implicit function for convex set of planes">vtkPlanes</a> version is an ImplicitFunction, which is suitable for use with the <a class="el" href="a00505.html" title="extract cells that lie either entirely inside or outside of a specified implicit...">vtkExtractGeometry</a>. The six frustum planes are in order: left, right, bottom, top, near, far<p>
Because this picker picks everything within a volume, the world pick point result is ill-defined. Therefore if you ask this class for the world pick position, you will get the centroid of the pick frustum. This may be outside of all props in the prop list.<p>
