When
I first heard of these two ways to designate how you are looking at an object
or group of objects when modeling they seemed pretty self-explanatory and easy
to explain. However when I was asked the difference I could only think of
arbitrary answers. I realized that I really had no clue which was which and how
to distinguish the two apart.
So
I decided to search the all-powerful and omnipotent Internet to find out just
what this difference is. I wanted to prove that I truly did know what someone
was saying when they asked about world space and local space in relation to the
virtual 3D world, the following is what I found.
World
Space: In relation to the 3D world this is the absolute XYZ coordinates of everything
within the viewport and all objects
Local
Space: This is the relative coordinates of an object, or reference object
While
searching for these two explanations of 3D spaces I also came across Screen
Space which deals mainly with a 2D space, but found it interesting nonetheless.
This is used to place objects at certain pixel positions on the screen.
I
hope this has helped you with determining the difference between world and
local space.
