1. Welcome to Introduction to Computer Graphics
CSE 470
Arizona State University
Spring 2017

2. Course Overview Categories of Computer Graphics:
1) Real-time rendering
> Topic of this course > Visualizing scientific data, games, or prep for pre-rendered > Interaction!
2) Pre-rendered > Advanced CG courses > Movies, commercials, art, entertainment, games
> Ray tracing, radiosity, photon mapping, ….

7. Pre-rendered Method: Radiosity
From Cornell University graphics group

8. Pre-rendered Method: Photon Mapping
From Henrik Wann Jensen’s

9. Course Plan Focus on real-time rendering
Follow the “pipeline” (see CG Overview ppt)
Implement main ideas with OpenGL
Review “pre-rendered” methods
Create cool programs!

10. Reason: more detail and realism
© Pixar
On 1995 computer hardware Toy Story average frame took 2 hours to render
On 2005 hardware Cars average frame took 15 hours to render despite 300x overall increase in compute power
Reason: more detail and realism

11. Changes … More work to do
Finding Nemo and Finding Dory
Hank: 2 years to create one scene!
Comparison
Side-by-side scene
Some details
