Course Overview

Dr. Frederick C Harris, Jr.

Fall 2012

Objectives

• Broad introduction to Computer Graphics– Software– Hardware– Applications

• Top-down approach• Shader-Based OpenGL

– OpenGL 3.1– Open GL ES 2.0– webGL

Prerequisites

• Good programming skills in C (or C++)

• Basic Data Structures– Linked lists– Arrays

• Geometry• Simple Linear Algebra

Resources

• Can run OpenGL on any system– Windows: check graphics card properties

for level of OpenGL supported– Linux– Mac: need extensions for 3.1 equivalence

• Get GLUT from web if needed– Provided on Macs– freeglut available on web

• Get GLEW from web• WebGL: most newer browsers
