Detects approximately when the node is visible on screen.
The VisibleOnScreenNotifier3D detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a [Camera3D]'s view. If you want nodes to be disabled automatically when they exit the screen, use [VisibleOnScreenEnabler3D] instead. [b]Note:[/b] VisibleOnScreenNotifier3D uses the render culling code to determine whether it's visible on screen, which also means that its [member Node3D.visible] must be [code]true[/code] to work correctly.
If [code]true[/code], the bounding box is on the screen. [b]Note:[/b] It takes one frame for the node's visibility to be assessed once added to the scene tree, so this method will return [code]false[/code] right after it is instantiated, even if it will be on screen in the draw pass.
