What is Computer Graphics?

● CG is the art and science of using the computer to make images.

● Study of methods (artistic, mathematical, algorithmic, software) and systems (mechanical, electronic, hardware) to create, control and manipulate pictoral data on the computer.


What makes Computer Graphics interesting?


Highly Interdisciplinary● Mathematics and Sciences

– Physics of light, color, motion, deformation...

– Geometry – Discrete, Differential, Projective

– Linear Algebra, Optimization

● Engineering and Systems

– Graphics processors, sensors, I/O devices

– Graphics libraries, windowing systems, parallel programming

● Art and Psychology

– Color and Perception theory, Composition, Form, Lighting

– Motion studies, perspective

Course Structure● Lectures, notes, textbook – see course

webpage.● Join mailing list (must before next class)● Programming Assignments: OpenGL on

Ubuntu LINUX, Groups of two, demos, at least 3 with the last being a multi-part project.

● Written Homework.● Quizes (Aug 31, Oct 19).● MidSem (Sep 12-17), EndSem (Nov 16-27).

Despicable Me, Illumination Entertainment 2010


Evaluation● Demos and viva, must run on my machine● Usually no open book exams● Assignments 50%, Exams+quizzes 45%,

Class participation 5%● Everything checked for plagiarism:

– Cite source if you borrow (even from your classmate).

– Minimum penalty is a FR.

Despicable Me, Illumination Entertainment 2010


Unsought Advice● Assignments – plan early, don't ask for

extensions.● Expect my PC to be evil - Works on my

machine, does not work on yours.● If you do not understand something - ask! ● If you think I am teaching something incorrect

– point it out.● If what I am teaching seems irrelevant – ask

why is it being taught.


SIGGRAPH● Special Interest Group on GRAPHics and

Interactive Techniques (of the ACM)● Largest, bestest? in Graphics research● SIGGRAPH Asia●


Course Courtesy – applies to you and me.

● We will be alert in class.● We will be honest.● When we borrow, we will always cite our

sources.● We will not be paranoid about grades –

please!● We will come to class in time.● We will have fun!
