2. TAs Needed n Undergrads needed to TA and grade for CS courses –TA labs for CS101, CS201, CS216, etc. –Office hours, grading for many undergrad courses n To apply, fill out form at: http://www.cs.virginia.edu/jobs/ n Get to know CS professors (get a reference) n Good for your resume n Undergrads play an important role in delivering high quality CS courses at UVa!

3. Final Exam n Thursday, December 12 th at 7:00 n Olsson 011

4. Assignment 4 n Trackball in Angel text is a little difficult to implement so it works for extreme rotations n I tried to protect you from quaternions, but… –http://isg.cs.tcd.ie/scollins/OpenGL/ n look for trackball.c and dinospin.c

5. Dinospin n Very easy example of how you can use trackball method and quaternions to accomplish intuitive user interface n Feel free to cut and paste this code to suit your needs

6. Making Movies n Concept n Storyboarding n Sound n Character Development n Layout and look n Effects n Animation n Lighting

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

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

41. Shooting Film For CG n Actors practice with maquettes n Maquettes replaced with laser dots –lasers on when camera shutter is closed n After each take, three extra shots –chrome ball for environment map for Stuart’s eyes –white and gray balls for lighting info

42. Match-moving n Film scanned n Camera tracking data retrieved n 3D Equalizer + Alias Maya to prepare (register) the digital camera n Once shot is prepared, 2D images rendered and composited with live action

Final Fantasy n Main characters > 300,000 polys n 1336 shots n 24,606 layers n 3,000,000 renders (if only rendered once) –typically 5 render revisions –render time per frame = 90 min n Most layers per shot 500 n 934,162 days of render time on one CPU –they used 1200 CPUs = 778 days of rendering

46. Final Fantasy n Renderman (Pixar) used for rendering –direct illumination –many hacks to fake global illumination n Maya used for modeling n Hair –Modeled is splines –Lighting and rendering complicated as well
