+–javax.media.j3d.PickShape PickShapesare used by the PickToolto provide information about the volume of space, segment, or infinite ray that the objects in the scene should be tested against. Java 3D supports the PickShapeslisted in table 16.1: Table 16.1 PickShapes supported by Java 3D PickShapes Description PickBounds PickBounds is a finite pick shape defined with a Bounds object. PickConeRay PickConeRay is an infinite cone ray pick shape. PickConeSegment PickConeSegment is a finite cone segment pick shape. PickCylinderRay PickCylinderRay is an infinite cylindrical ray pick shape. PickCylinderSegment PickCylinderSegment is a finite cylindrical segment pick shape. PickPoint PickPoint is a pick shape defined as a single point. PickRay PickRay is an infinite ray pick shape. PickSegment PickSegment is a line segment pick shape. By using the appropriate PickShapeyou can find the objects in your scene that Fall within a given volume (PickBounds) Intersect with an infinite cone, such as a ray of light shining from a torch (PickConeRay) Intersect with a finite length cone, such as the objects within a torch ray, within a given distance (PickConeSegment) Intersect with a laser beam (PickCylinderRay) Intersect with a blind-man s stick (PickCylinderSegment) Intersect with a point (PickPoint) Intersect with a very narrow laser beam (PickRay) Intersect with a very narrow blind-man s stick (PickSegment) 16.3 PickTool java.lang.Object | +–com.sun.j3d.utils.picking.PickTool PickToolis the base class for picking operations. The picking methods will return a PickResultobject for each object picked, which can then be queried to obtain more detailed information about the specific objects that were picked. The pick mode specifies the detail level of picking before the PickResultis returned (see table 16.2). Table 16.2 PickTools PickTool Mode Description BOUNDS Pick using the bounds of the pickable nodes. The PickResult returned will contain the SceneGraphPath to the picked Node. GEOMETRY Pick using the geometry of the pickable nodes. The PickResult returned will contain 267
