1 Replaced by Transform in VRML2.0
2 This group node performs a push (save) of the traversal state before traversing its children and a pop (restore) after traversing them.
3 This isolates the separator's children from the rest of the scene graph.
4 A separator can include lights, cameras, coordinates, normals, bindings, and all other properties.
5 Separators can also perform render culling.
6 Render culling skips over traversal of the separator's children if they are not going to be rendered, based on the comparison of the separator's bounding box with the current view volume.
7 Culling is controlled by the renderCulling field.
  • These are set to AUTO by default, allowing the implementation to decide whether or not to cull.
