first. The result is that the shapes under the annotation node are rendered \&on top of the rest of the scene. This node is derived from \*(CbSoSeparator\f1, so it saves and restores traversal state for all actions. .sp Note that if more than one annotation node is present in a graph, the order in which \&they are traversed determines the stacking order \(em later nodes are rendered on top of earlier ones. Also note that since depth buffer comparisons are disabled, complex 3D objects may not be rendered correctly \&when used under annotation nodes. .sp 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. .SH METHODS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbSoAnnotation\*(Cr() .br .in 1i \f1Creates an annotation node with default settings. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crstatic SoType .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbgetClassTypeId\*(Cr() .br .in 1i \f1Returns type identifier for this class. .sp .in 0.5i .SH ACTION BEHAVIOR \*(CbSoGLRenderAction .br .in 1i \f1Delays rendering its children until all other nodes have been traversed, turning off depth buffer comparisons first. .sp .in 0.5i \*(CbSoCallbackAction, SoGetBoundingBoxAction, SoGetMatrixAction, SoRayPickAction, SoSearchAction .br .in 1i \f1Same as \*(CbSoSeparator\f1 .sp .in 0.5i .SH FILE FORMAT/DEFAULTS .nf \*(CrAnnotation { .in 1i .ta 20m renderCaching AUTO boundingBoxCaching AUTO renderCulling AUTO pickCulling AUTO .in 0.5i }
