The 3D Environment
If you are used to working in the 2D environment or on a timeline with cuts, dissolves,
and 2D effects, it may be difficult to wrap your head around the concepts of 3D space.
This section provides some background for those who are not familiar with 3D
animation. In particular, it introduces the notion of coordinate systems and distance
units.
Coordinate Systems
Coordinate systems allow any point in three-dimensional space to be represented by a
triplet of numbers (X, Y, Z).
Cartesian Coordinates
One essential concept that a first-time user of 3D computer graphics should
understand is the notion of working within a virtual three-dimensional space using a
two-dimensional user interface. In the classic Euclidean/Cartesian mathematical
