Producing Animation: The 3D CGI Production Process

Catherine Winder and Zahra Dowlatabadi give an overview of the 3D CGI production process from pre-production through final film/video output.

We explore the nuts and bolts of production in Producing Animation's Chapter 9 starting with the description of the role of the producer during this phase. The production pipelines for both 2D and 3D CGI projects are also outlined here. Using flow charts, we define each stage, in addition to describing the specific background experience required for individual job categories. The 2D production pipeline starts with workbook and goes all the way through final checking, compositing and film output. The 3D CGI production process emphasizes the importance of pre-production and how integral it is to setting up a smooth production path. It covers design, modeling and rigging steps through touch up and final film/video output. The following is the introduction to 3D CGI production set up.

3D Computer Generated Imagery (3D CGI): From Pre-Production Through Final Film/Video Output
Perhaps the best way to understand CGI is to consider it a merger of two methods of filmmaking: 2D animation and live-action. The process for generating CGI animated projects is very similar in many ways to traditional animation, with some subtle but significant differences in production procedures. Unlike hand-drawn animation, in CGI, artists must create a three-dimensional world in the computer. Three-dimensional sets must be built, lit and painted, much in the way that sets are constructed for live-action films. CGI also resembles live-action filmmaking in terms of spatial conceptualization, lighting, cinematography, scene hook-ups and blocking of actor's movements. To get from idea to screen, however, CGI follows the traditional animation model in which the artist must go through a series of steps to first create and then define the image.

It is important to keep in mind that unlike traditional 2D animation, which follows a fully established path, CGI production is still in the midst of defining and standardizing its processes. Depending on the style of the CGI show -- for example, cutout animation versus 3D -- the software used and the actual production process is different. The following is a basic outline of the production steps involved in setting up a 3D CGI project.
1. Design
2.Modeling
3.Rigging
4.Surfaces (texture and color)
5.Staging/workbook
6.Animation
7.Lighting
8.Effects
9.Rendering
10.Composite
11.Touchup
12.Final film/video output

The part that fascinates me the most is how they take all that computer animation, mix it with the live stuff, and then convert it onto a 35mm movie film to copy them for distribution in cinema theaters. Is that a hard or easy process from CGI to film? I would love to know how that is done. Your response is greatly appreciated. Thank you and have a great mother's day weekend.
