Undergrads needed to TA and grade for CS courses
– TA labs for CS101, CS201, CS216, etc.
– Office hours, grading for many undergrad courses

To apply, fill out form at:
http://www.cs.virginia.edu/jobs/

Get to know CS professors (get a reference)

Assignment 4
Trackball in Angel text is a little difficult
to implement so it works for extreme
rotations
 I tried to protect you from quaternions,
but…

– http://isg.cs.tcd.ie/scollins/OpenGL/

look for trackball.c and dinospin.c
Dinospin
Very easy example of how you can use
trackball method and quaternions to
accomplish intuitive user interface
 Feel free to cut and paste this code to
suit your needs

Pixar’s Lasseter is a genius – “Nothing
gets in the way of the story”
Storyboarding

Explicitly define
– Scenes
– Camera shots
– Special effects
– Lighting
– Scale

Used as guide by
animators
Sound
Voice recording of talent completed
before animation begins
 Animations must match the voice over
 A puppeteer once told me that the
voice makes or breaks a character

 6 main challenges

– Lip sync
– Match-move (CG to live-action)
– Fur
– Clothes
– Animation tools
– Rendering, lighting, compositing

Shooting Film For CG
Actors practice with maquettes
 Maquettes replaced with laser dots

– lasers on when camera shutter is closed

After each take, three extra shots
– chrome ball for environment map for Stuart’s
eyes
– white and gray balls for lighting info
Match-moving
Film scanned
 Camera tracking data retrieved
 3D Equalizer + Alias Maya to prepare
(register) the digital camera
 Once shot is prepared, 2D images
rendered and composited with live
action

Final Fantasy




Main characters > 300,000 polys
1336 shots
24,606 layers
3,000,000 renders (if only rendered once)
– typically 5 render revisions
– render time per frame = 90 min


Most layers per shot 500
934,162 days of render time on one CPU
– they used 1200 CPUs = 778 days of rendering
Final Fantasy

Renderman (Pixar) used for rendering
– direct illumination
– many hacks to fake global illumination
Maya used for modeling
 Hair

– Modeled is splines
– Lighting and rendering complicated as well
