the SceneGraphPath to the picked Node. Geometry nodes (Web hosting domain names)
the SceneGraphPath to the picked Node. Geometry nodes in the scene must have the ALLOW_INTERSECT capability set for this mode. Same as GEOMETRY, but the PickResult will include information on each intersection of the pick shape with the geometry. The intersection information includes the subprimitive picked (i.e., the point, line, triangle, or quad), the closest vertex to the center of the pick shape, and the intersection’s coordinate, normal, color, and texture coordinates. To allow this to be generated, Shape3D and Morph nodes must have the ALLOW_GEOMETRY_READ capability GEOMETRY_INTERSECT_INFO set, and GeometryArrays must have the ALLOW_FORMAT_READ, ALLOW_COUNT_READ, and ALLOW_COORDINATE_READ capabilities set, plus the ALLOW_COORDINATE_INDEX_READ capability for indexed geometry. To query the intersection color, normal, or texture coordinates, the corresponding READ capability bits must be set on the GeometryArray. The utility method PickTool.setCapabilities(Node, int)can be used before the scenegraph is made live to set the capabilities of Shape3D, Morph, or Geometrynodes to allow picking. A PickResultfrom a lower level of detail pick can be used to inquire about more detailed information if the capability bits are set. This can be used to filter the PickResultsbefore the more computationally intensive intersection processing. For example, the application can do a BOUNDSpick and then selectively query intersections on some of the PickResults. This will save the effort of doing intersection computation on the other PickResults. However, querying the intersections from a GEOMETRYpick will make the intersection computation happen twice, so use GEOMETRY_INTERSECT_INFOif you want to inquire the intersection information on all the PickResults. When using pickAllSortedor pickClosestmethods, the picks will be sorted by the distance from the start point of the pick shape to the intersection point. Morphnodes cannot be picked using the displayed geometry in GEOMETRY_INTERSECT_INFOmode due to limitations in the current Java3D core API (the current geometry of the Morphcannot be queryed). Instead, they are picked by using the geometry at index 0 in the Morph. This limitation may be eliminated in a future release of Java3D. If the pick shape is a PickBounds, the pick result will contain only the scenegraph path, even if the mode is GEOMETRY_INTERSECT_INFO. 16.4 PickCanvas java.lang.Object | 268
