What do you need to know?

7

A programming language in the C-family C / C++ All Assignments need to be submitted in C / C++

NOT Graphics / OpenGL / linear algebra We will cover what you need in class

Reference books

8

• Computer Graphics Using OpenGL, by Francis S. Hill, Jr., 2nd or 3rd edition, Prentice Hall, ISBN: 0023548568.

• OpenGL Programming Guide, Fourth Edition: The Official Guide to Learning OpenGL, Version 1.5, by Woo et al., Addison Wesley, ISBN: 0201604582.

Required Software

9

Microsoft Visual Studio 2008 or 2010 http://www.microsoft.com/express/Downloads/#2010-Visual-CPP

Your finished programs must compile and run under Windows OS You can use UNIX, Linux, or Mac OS X for

development, but we don’t support them

Grading

10

The final grade depends on: Continuous assessment: 50%

Assignment average: 40%Midterm test: 10%

Final exam: 50%

Assignment

11

About 6 short programming assignments: 1 student independently Submit via email The deadline is non-negotiable

Academic Honesty

12

You must identify code that is not your own Mention original author(s) in source or README

files Do not remove original headers! Do not collaborate with other students

What is this course about? Basic goal: Teach you the fundamentals for

writing your own graphics applications We want you to:

learn how to programming in OpenGL understand computer graphics concepts have some fun!

What happened in the past 8 years? Interactive is delivering near-offline quality

1,000,000x faster GPUs have taken advantage of semiconductor

trends to deliver performance GPU strengths/weaknesses have sparked

innovation in algorithms and software
