Class PickInfo

    java.lang.Object
      javax.media.j3d.PickInfo

    public class PickInfo

extends java.lang.Object

The PickInfo object contains the computed information about a pick hit. The detailed information about each intersection of the PickShape with the picked Node can be inquired. The PickInfo object is constructed with basic information and more detailed information can be generated by setting the appropriate mask to the flag argument in the pick methods of BranchGroup and Locale.

Since:
  Java 3D 1.4
See Also:
  `Locale`, `BranchGroup`

Nested Class Summary
`class` | `PickInfo.IntersectionInfo` The IntersectionInfo object holds extra information about an intersection of a PickShape with a Node as part of a PickInfo.

Field Summary
`static int` | `ALL_GEOM_INFO` Specifies that this PickInfo returns all the closest intersection geometry informations.
`static int` | `CLOSEST_DISTANCE` Specifies that this PickInfo returns the closest intersection distance.
`static int` | `CLOSEST_GEOM_INFO` Specifies that this PickInfo returns only the closest intersection geometry information.
`static int` | `CLOSEST_INTERSECTION_POINT` Specifies that this PickInfo returns the closest intersection point.
`static int` | `LOCAL_TO_VWORLD` Specifies that this PickInfo returns the computed local to vworld transform.
`static int` | `NODE` Specifies that this PickInfo returns the computed intersected Node object.
`static int` | `PICK_BOUNDS` Specifies a Pick using the bounds of the pickable nodes.
`static int` | `PICK_GEOMETRY` Specifies a Pick using the geometry of the pickable nodes.
`static int` | `SCENEGRAPHPATH` Specifies that this PickInfo returns the computed SceneGraphPath object.

Method Summary
`double` | `getClosestDistance()` Retrieves the distance between the start point of the pickShape and the closest intersection point.
`Point3d` | `getClosestIntersectionPoint()` Retrieves the reference to the closest intersection point in this PickInfo object.
`PickInfo.IntersectionInfo[]` | `getIntersectionInfos()` Retrieves the reference to the array of intersection results in this PickInfo object.
`Transform3D` | `getLocalToVWorld()` Retrieves the reference to the LocalToVworld transform of the picked node in this PickInfo object.
`Node` | `getNode()` Retrieves the reference to the picked node, either a Shape3D or a Morph, in this PickInfo object.
`SceneGraphPath` | `getSceneGraphPath()` Retrieves the reference to the SceneGraphPath in this PickInfo object.

Method Detail

### getSceneGraphPath

    public SceneGraphPath getSceneGraphPath()

  Retrieves the reference to the SceneGraphPath in this PickInfo object.

  Returns:
    the SceneGraphPath object, or null if flag is not set with SCENEGRAPHPATH.
  See Also:
    `Locale`, `BranchGroup`

### getNode

    public Node getNode()

  Retrieves the reference to the picked node, either a Shape3D or a Morph, in this PickInfo object.

  Returns:
    the picked leaf node object, or null if flag is not set with NODE.
  See Also:
    `Locale`, `BranchGroup`

### getLocalToVWorld

    public Transform3D getLocalToVWorld()

  Retrieves the reference to the LocalToVworld transform of the picked node in this PickInfo object.

  Returns:
    the local to vworld transform, or null if flag is not set with LOCAL_TO_VWORLD.
