Grading For CSc 4820 students: Mid-term exam: 20% Homework assignments: 25% Projects: 50% Class participation 5% For CSc 6820 students: Homework assignments: 15% Projects: 50% Graduate student project 30% Class participation 5%

Grading The grading scale is as follows: A: 90+ B: C: D: 60 – 69 F: < 60 Make-up exams are given at the discretion of the instructor. Students who are unable to take an exam for a valid reason should notify the instructor before the exam time.

Tentative Schedule Tentative course schedule is available online at /home.htmhttp:// 6820/home.htm

Projects & Assignments About 4 projects and 5 homework assignments All projects and homework assignments are individual work Assignment and project requirements may be different for students enrolled in CSc Each graduate student needs to complete an additional individual project OpenGL is the primary choice for project development.

Projects & Assignments Projects are due on the assigned date. Late submissions may result in reduction of grades. Project submissions later than three days will not be accepted unless you make prearrangements Students should keep copies of their projects and assignments until after they receive their grades.

Projects Overview Project 1: basic OpenGL and GLUT programming Project 2: transformation, viewing, projection, and basic interaction Project 3: lighting, surface materials, and animation Project 4: texture mapping, fog, transparency, animation

Homework Overview Homework 0: set up your OpenGL programming environment, get to know your graphics card Homework #1: transformation, view, and projection Homework #2: lighting, surface materials Homework #3: texture mapping, transparency, modeling

Any questions?

What is Computer Graphics? The word “Computer Graphics” means different things to different people. We will focus on 3D interactive computer graphics: – How to create and store geometry objects (Modeling) – How to manipulate geometry objects (Animation) – How to generate and display images of geometry objects (Rendering) – User interaction Images courtesy Discreet Lord of the Rings

Major Fields in Computer Graphics Modeling How to create and store geometry objects Animation How to manipulate geometry objects Rendering How to generate and display images of geometry objects

General Goals of CG Modeling & rendering: create photo-realistic images Is it real or is it CG? Animation: create visually realistic simulation Towards true real-time performance 60 frames per second Flexible user interaction Use CG techniques to advance other research fields Scientific visualization and engineering simulation

Major Applications Entertainment 3D games Films Training and education E.g. flight simulator, military training Scientific visualization E.g. bioinformatic visualization, data visualization Other

What I will teach in this course A general understanding of the following: The fundamentals of 3D graphics pipeline 3D transformation, camera manipulation, lighting, texture mapping, frame buffer operations, etc. The basics of Graphics Processing Unit, shaders and shader programming

What I will teach in this course The fundamentals of 3D modeling and animation. The current state of the art in computer graphics and expected near term advances.

Why study computer graphics 3D graphics is everywhere. The graphics related industry is growing very fast. Sales of video-game software in the United States: $9.9 billion in 2005 (compared with the $11.4 billion sale by music industry in 2004). By 2010, U.S. sales of video games are expected to grow to $15 billion. Video gaming is expected to generate more than 250,000 jobs by 2009 The average age of gamers was 33 years, and 25% of players were older than 50.

Why study computer graphics Non-graphics related businesses are using graphics contents to reach out to their customers (e.g. virtual worlds). anizations_in_Second_Lifehttp://en.wikipedia.org/wiki/Businesses_and_org anizations_in_Second_Life
