 		[Camera3D] is a special node that displays what is visible from its current location. Cameras register themselves in the nearest [Viewport] node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the camera will register in the global viewport. In other words, a camera just provides 3D display capabilities to a [Viewport], and, without one, a scene registered in that [Viewport] (or higher viewports) can't be displayed.

 		MeshInstance3D is a node that takes a [Mesh] resource and adds it to the current scenario by creating an instance of it. This is the class most often used render 3D geometry and can be used to instance a single [Mesh] in many places. This allows reuse of geometry which can save on resources. When a [Mesh] has to be instanced more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance3D] instead.
