Returns the 2D coordinate in the [Viewport] rectangle that maps to the given 3D point in worldspace.
[b]Note:[/b] When using this to position GUI elements over a 3D viewport, use [method is_position_behind] to prevent them from appearing if the 3D point is behind the camera:
[codeblock]
# This code block is part of a script that inherits from Node3D.
# `control` is a reference to a node inheriting from Control.
control.visible = not get_viewport().get_camera().is_position_behind(global_transform.origin)
control.rect_position = get_viewport().get_camera().unproject_position(global_transform.origin)
[/codeblock]
