The VisibilityNotifier3D 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.
|
|
[b]Note:[/b] VisibilityNotifier3D uses an approximate heuristic for performance reasons. It doesn't take walls and other occlusion into account. If you need exact visibility checking, use another method such as adding an [Area3D] node as a child of a [Camera3D] node.

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.
