Detailed information about the pick and each intersection of the PickShape with the picked Node can be inquired. The PickResult is constructed with basic information and more detailed information is generated as needed. The additional information is only available if capability bits on the scene graph Nodes are set properly; <A HREF="PickTool.html#setCapabilities(javax.media.j3d.Node, int)"> <code>PickTool.setCapabilties(Node, int)</code></A> can be used to ensure correct capabilites are set. Inquiring data which is not available due to capabilties not being set will generate a <code>CapabilityNotSet</code> exception. <p> A PickResult can be used to calculate intersections on Node which is not part of a live scene graph using the constructor which takes a local to VWorld transformation for the Node. <p> Pick hits on TriangleStrip primitives will store the triangle points in the PickIntersection with the verticies in counter-clockwise order. For triangles which start with an odd numbered vertex this will be the the opposite of the order of the points in the TriangleStrip. This way the triangle in the PickIntersection will display the same was as the triangle in the strip. <p> If the Shape3D being picked has multiple geometry arrays, the arrays are stored in the PickResult and referred to by a geometry index. <p> If the Shape3D refers to a CompressedGeometry, the geometry is decompressed into an array of Shape3D nodes which can be inquired. The geometry NodeComponents for the Shape3D nodes are stored and used as if the Shape3D had multiple geometries. If there are multiple CompressedGeometries on the Shape3D, the decompressed Shape3Ds and GeometryArrays will be stored sequentially. <p> The intersection point for Morph nodes cannot be calculated using the displayed geometry due to limitations in the current Java3D core API (the current geometry of the the Morph cannot be inquired). Instead the geometry at index 0 in the Morph is used. This limitation may be eliminated in a future release of Java3D.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!--
