superclass for 3D geometric pickers (uses ray cast)

The ray is defined from a point defined in window (or pixel) coordinates, and a point located from the camera's position.<p>
<a class="el" href="a01212.html" title="superclass for 3D geometric pickers (uses ray cast)">vtkPicker</a> may return more than one <a class="el" href="a01318.html" title="represents an 3D object for placement in a rendered scene">vtkProp3D</a>, since more than one bounding box may be intersected. <a class="el" href="a01212.html" title="superclass for 3D geometric pickers (uses ray cast)">vtkPicker</a> returns the list of props that were hit, the pick coordinates in world and untransformed mapper space, and the prop (<a class="el" href="a01318.html" title="represents an 3D object for placement in a rendered scene">vtkProp3D</a>) and mapper that are "closest" to the camera. The closest prop is the one whose center point (i.e., center of bounding box) projected on the ray is closest to the camera.<p>
