3D computer animation combines 3D modeling with programmed movement. Models are constructed out of geometrical vertices, faces, and edges in a true 3D coordinate system. Objects are sculpted much like real clay or plaster, working from general forms to specific details with various sculpting tools. A bone/joint system is set up to deform the 3d mesh ie. to make a humanoid model walk. In a process called rigging, the virtual marionette is given various controllers and handles for an animator to manipulate.
