  1. CS 445Introduction to Computer Graphics Fall 2006Aaron Bloomfield

  2. Overview • Introduction • What is computer graphics? • Applications • What is it good for? • Syllabus • What will I learn in this course? • Coursework • How much work will there be?

  3. What is Computer Graphics? • Sliced by specialty • Imaging = representing 2D images • Modeling = representing 3D objects • Rendering = building 2D images from 3D models • Animation = simulating changes over time • Hardware = computer architecture for graphics

  4. What is Computer Graphics? • Sliced by task • Creating pictures on a computer • Interacting with those pictures • Drawing those pictures faster • Displaying those pictures bigger, brighter • Simulating physical phenomena • Visualization of complex data • Acquiring real-world geometry • Simulating plants • Video games • Breaking stuff • …

  5. Why is Graphics Cool? • Interdisciplinary • Biology, Physics, Math, Psychology, CS, Art • Visual • Interactive • Work can be demoed to technically illiterate friends • Movies • Games • Money • Video games: $11B (2004) • Movies: $8.5B (2001)

  6. Overview • Introduction • What is computer graphics? • Applications • What is it good for? • Syllabus • What will I learn in this course? • Coursework • How much work will there be?

  33. Overview • Introduction • What is computer graphics? • Applications • What is it good for? • Syllabus • What will I learn in this course? • Coursework • How much work will there be?

  34. Coursework • Exams (25%) • In class (Oct 14 and Dec 7) • Programming Assignments (every two weeks) (50%) • Warmup (due 31 August - ONE WEEK FROM TODAY) • Image Processing (due 14 September) • Ray Tracer (due 28 September) • Virtual Rubik (due 12 October) • NPR (due 26 October) • Final Project (25%) • Do something cool! • Proposals due 9 November

  35. Programming Assignments • When? • Every two weeks • Where? • Anywhere you want, e.g. home or Small Hall PC Lab • How? • Portable code, so any OS you like • But we have to grade it! • Typically C and C++, OpenGL, GLUT • What? • Basic feature lists • Extra credit lists • Art contest

  36. Collaboration Policy • You must write your own code • You must reference your sources of any ideas/code • It’s OK to … • Talk with other students about ideas, approaches, etc. • Get ideas from information in books, web sites, etc. • Get “support” code from example programs • But, you must reference your sources • It’s NOT OK to … • Share code (no matter how trivial) with another student • Use ideas or code acquired from another sources without attribution • Directly debug another student’s program (i.e., by looking at their code) • Do not test us on this – zero tolerance in effect

  37. Administrative Matters • http://www.cs.virginia.edu/~cs445/ • Instructor: Aaron Bloomfield • TA: Jason Mars • Office hours for both will be posted on the website

  38. Required Book

  39. Recommended Book

  40. More, more, MORE! • Sequence of advanced graphics courses at UVA: • CS 447: Image Synthesis (Greg Humphreys) • Modeling light and materials (Rendering) • Spring 2007 • There will probably be an additional “follow-on” graphics class offered in the spring of 2008
