  1. Making Movies Aaron Bloomfield CS 445: Introduction to Graphics Fall 2006 (Slide set originally by David Brogan)

  2. Making Movies • Concept • Storyboarding • Sound • CharacterDevelopment • Layout and look • Effects • Animation • Lighting

  3. Concept • “Nothing gets in the way of the story” • John Lasseter (Pixar)

  4. Explicitly define Scenes Camera shots Special effects Lighting Scale Used as guide by animators Story-boarding

  5. 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. Character Development • 300 Drawings

  7. Character Development • 40 Sculptures

  8. Character Development • Computer Models

  9. Layout & Look • Build scenery • Match colors

  10. Matchmoving • CG camera must exactly match the real camera • Position • Rotation • Focal length • Aperature • Easy when camera is instrumented • Hard to place CG on moving objects on film

  11. Match-moving

  12. Matchmoving • Known patterns in live action made it easier to track – furniture, wall paper • 2D – 3D conversion in Maya

  13. Shooting Film For CG • Actors practice with maquettes (small scale models) • 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

  14. Matchmoving • 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

  27. Toy Story (1995) • 77 minutes long; 110,064 frames • 800,000 machine hours (91 years!) of rendering • 1 terabyte of disk space • 3.5 minutes of animation produced each week (maximum) • Frame render times: 45 min – 20 hours • 110 Suns operating 24-7 for rendering • 300 CPU’s

  28. Toy Story • Texture maps on Buzz: 189 • (450 to show scuffs and dirt) • Number of animation ‘knobs’ • Buzz – 700 • Woody – 712 • Face – 212 • Mouth – 58 • Sid’s Backpack – 128 • Number of leaves on trees – 1.2 mil • Number of shaders – 1300 • Number of storyboards – 25,000

  29. 80 minutes long, 122,699 frames 1400 processor render farm Render time of 10 min to 3 days Direct to video film Software tools Alias|Wavefront Amazon Paint RenderMan Toy Story 2

  30. Newman! • Subdivision-surfaces • Polygonal hair (head) • Texture mapped on arms • Sculpted clothes • Complex shaders

  31. Devil’s in the Details • Render in color • Convert to NTSC B/W • Add film effects • Jitter • Negative scratches • Hair • Static

  32. Images Shadows?

  33. Images

  35. Stuart Little • 500 shots with digital character • 6 main challenges • Lip sync • Match-move (CG to live-action) • Fur • Clothes • Animation tools • Rendering, lighting, compositing

  36. Stuart Little • 100+ people worked on CG • 32 color/lighting/composite artists • 12 technical assistants • 30 animators • 40 artists • 12 R&D

  38. Final Fantasy http://www.arstechnica.com/wankerdesk/01q3/ff-interview/ff-interview-2.html

  39. Final Fantasy • First ever animated feature to attempt photorealistic CGI humans • Second biggest box office flop ever (lost over $124M) • 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

  40. 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

  41. The good Jar-Jar’s ears (cloth simulation) Jar-Jar’s facial animation Sets Were only as high as the tallest character in the film Above that was all CG Was the first interaction between CGI and humans The bad Jar-Jar Jar-Jar Jar-Jar Jar-Jar Star Wars I
