Considerations for a Full CG-Animated Feature Pipeline
However, because there are no photographic source
plates, scanning/input and matchmove are not the starting point
of an animation pipeline; rather camera layout in the 3D system
and blocking animation are the starting points.
Sequences are collections of shots that are conceptually
related by their role in the story.Assignments
are based on sequence delivery deadlines, and sequence deliveries
build into a reel lock in which a full reel of the film is fed from
final render (meaning the approved CG render prior to color
grading) into post-production and ultimately edited in to the reel,
color graded, and approved for film-out.
CG Feature Animation Pipeline
Storyboard Animatics and Previs
Production Design and Look Development
Look development is the process of taking sample sequence(s) and pushing them through the entire pipeline (all the way to film-out) in order to find the right way to translate the production designs into a CG look.
Layout and Set Dressing
Modeling, Texturing, and Articulation (Rigging)
In large feature animation pipelines, this may constitute as many as eight departments (one each of modeling, shading, texture painting, and rigging for characters and environments).
Character Animation, Character Simulation, and Crowds
Lighting and Compositing
it is often a very precise and time-consuming process, Additionally, in animation, decomposition of shots into layers of elements, and subsequent compositing, is usually done in the lighting department.

A fast, high-capacity network.
