START EARLY !!Course will involve some understanding of mathematical, geometrical concepts taught (explicitly tested on midterm, open book take home written assignments at end)Prerequisites: Solid C/C++/Java programming background. Linear algebra (review on Mon) and general math skillsShould be a difficult, but fun and generously graded courseRelated coursesRelated coursesCOMS 4162, follow on to 4160 taught by me in the spring. I hope many of you will enroll in that (lot of fun last year)Many 6000-level courses (e.g. COMS 6160 High Quality Real-Time Rendering taught by me last year in fall)Part of Vision and Graphics track in BS and MS programs. Columbia Vision and Graphics CenterOther related courses: Computer Vision, Robotics, User Interfaces Computational Geometry, …To Do To Do Look at websiteVarious policies etc. for course. Send me e-mail if confused.Skim assignments if you want. All are readyAssignment 0, Due Sep 13 Tue (see website). Send e-mail to [email protected] telling us about yourself and sending us a digital photo (so we can put names to faces).Any questions?HistoryHistoryBrief history of significant developments in fieldCouple of animated shorts for funTowards end of course: movie, history of CGWhat is Computer Graphics?What is Computer Graphics?Anything to do with visual representations on a computerIncludes much of 2D graphics we take for grantedAnd 3D graphics modeling and rendering (focus of course)Auxiliary problems: Display devices, physics and math for computational problemsThe term Computer Graphics was coined by William Fetter of Boeing in 1960First graphic system in mid 1950s USAF SAGE radar data (developed MIT)2D Graphics2D GraphicsMany of the standard operations you’re used to:TextGraphical User Interfaces (Windows, MacOS, ..)Image processing and paint programs (Photoshop, …)Drawing and presentation (Powerpoint, …)How far we’ve come: TEXTHow far we’ve come: TEXTManchester Mark IDisplayFrom Text to GUIsFrom Text to GUIsInvented at PARC circa 1975.
