83 This group node delays rendering its children until all other nodes
84 have been traversed, turning off depth buffer comparisons first. The
85 result is that the shapes under the annotation node are rendered on top
86 of the rest of the scene. This node is derived from SoSeparator, so it
87 saves and restores traversal state for all actions.
88 Note that if more than one annotation node is present in a graph, the
90 order in which they are traversed determines the stacking order — later
91 nodes are rendered on top of earlier ones. Also note that since depth
92 buffer comparisons are disabled, complex 3D objects may not be rendered
93 correctly when used under annotation nodes.
94 Also note that the annotation node does nothing special when picking
96 along a ray. That is, it does not modify the sorting order of inter‐
97 sected objects based on which ones are under annotation nodes. If your
98 application uses annotation nodes and you want to ensure that objects
99 under them are picked "in front of" other objects, you can tell the
100 pick action that you want to pick all objects along the ray and then
101 scan through the paths in the resulting picked point instances to see
102 if any of them passes through an annotation node. Your program can then
103 decide what to do in such a case.
