Detailed Description

superclass for 3D geometric pickers (uses ray cast)

vtkPicker is used to select instances of vtkProp3D by shooting a ray into a graphics window and intersecting with the actor's bounding box. The ray is defined from a point defined in window (or pixel) coordinates, and a point located from the camera's position.

vtkPicker may return more than one vtkProp3D, since more than one bounding box may be intersected. vtkPicker returns an unsorted list of props that were hit, and a list of the corresponding world points of the hits. For the vtkProp3D that is closest to the camera, vtkPicker returns the pick coordinates in world and untransformed mapper space, the prop itself, the data set, and the mapper. For vtkPicker the closest prop is the one whose center point (i.e., center of bounding box) projected on the view ray is closest to the camera. Subclasses of vtkPicker use other methods for computing the pick point.

See also: vtkPicker is used for quick geometric picking. If you desire more precise picking of points or cells based on the geometry of any vtkProp3D, use the subclasses vtkPointPicker or vtkCellPicker. For hardware-accelerated picking of any type of vtkProp, use vtkPropPicker or vtkWorldPointPicker.
