and transformations exist within coordinate systems called spaces.
World space is the coordinate
system for the entire scene. Its origin is at the center of the
scene. The grid you see in view windows shows the world space axes.
Object space is the coordinate
system from an object’s point of view. The origin of object space
is at the object’s pivot point, and its axes are rotated with the
Local space is similar to object space, however
it uses the origin and axes of the object’s parent node in the hierarchy
of objects. This is useful when you haven’t transformed the object
itself, but it is part of a group that is transformed.
