public class SoAnnotation extends SoSeparator
SoSeparator
, so it saves and restores traversal state for all actions.
Rendering order:
Objects under an SoAnnotation
node are rendered after "delayed" transparent objects. See SoGLRenderAction
for more information about rendering order. Note that if more than one annotation node is present in a graph, the order in which they are traversed determines the stacking order - later nodes are rendered on top of earlier ones.
Note: Because depth buffer comparisons are disabled, complex 3D objects may not be rendered correctly when used under annotation nodes.
Picking:
Also note that the annotation node does nothing special when picking along a ray. That is, it does not modify the sorting order of intersected objects based on which ones are under annotation nodes. If your application uses annotation nodes and you want to ensure that objects under them are picked "in front of" other objects, you can tell the pick action that you want to pick all objects along the ray and then scan through the paths in the resulting picked point instances to see if any of them passes through an annotation node. Your program can then decide what to do in such a case.
File format/default:

boundingBoxCaching | AUTO |
renderCulling | AUTO |
pickCulling | AUTO |
fastEditing | false |
Action behavior:
SoGLRenderAction
Delays rendering its children until all other nodes have been traversed, turning off depth buffer comparisons first.
