Full Day / Beginning


An inside look into the production of "Toy Story," the world's first feature-length computer-animated film. Presentations by members of the crew take the audience through each stage of the production pipeline: art and design, modeling, shading, layout, animation, lighting, and effects.

Who Should Attend

Analyze model and choose technique
Alias (turn-key modeler)
pet/pat (proprietary deformation tools)
Pure mdl (proprietary procedural scripting language)
C code (UNIX based software development language)
psys (proprietary particle system generator)

Case study: Buzz Lightyear

Hair (shaders vs. geometry)
Skin
Clothing (jeans -> blacklight)

2:45 pm: Q&A

Last step of modeling/first step of animation
First step into the 3D world

Research and inspiration
"Twins" case study
"Apocalypse Now"
Toy commercials

Film grammar
Perspective and lens choices: tripods, cranes, zooms
Moves: why we don't fly the camera around all the time
The camera move as an homage: Mann cam, Brannagh cam, Spielberg cam

Anatomy of an homage
t14 and "Raiders of the Lost Ark"

Overview
Movement = meaning (nothing moves without a meaning)

The shot in its context
