A box-shaped region of 3D space that detects whether it is visible on screen.
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 screen_entered signal, and likewise it will emit a 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.
Note: 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 Node3D.visible is set to true.

is_on_screen ( ) const |
Emitted when the VisibleOnScreenNotifier3D enters the screen.
Emitted when the VisibleOnScreenNotifier3D exits the screen.
AABB(-1, -1, -1, 2, 2, 2)
The VisibleOnScreenNotifier3D's bounding box.
Returns true if the bounding box is on the screen.
Note: It takes one frame for the VisibleOnScreenNotifier3D's visibility to be assessed once added to the scene tree, so this method will always return false right after it is instantiated.
