 	<brief_description>
-		Detects approximately when the node is visible on screen.
+		A box-shaped region of 3D space that detects whether it is visible on screen.
 	</brief_description>
 	<description>
-		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.
+		[VisibleOnScreenEnabler3D] represents a box-shaped region of 3D space. When any part of this region becomes visible on screen or in a [Camera3D]'s view, it will emit a [signal screen_entered] signal, and likewise it will emit a [signal screen_exited] signal when no part of it remains visible.
+		If you want a node to be enabled automatically when this region is visible on screen, use [VisibleOnScreenEnabler3D].
+		[b]Note:[/b] [VisibleOnScreenNotifier3D] uses an approximate heuristic that doesn't take walls and other occlusion into account, unless occlusion culling is used. It also won't function unless [member Node3D.visible] is set to [code]true[/code].
