Why Study Computer Graphics?

Graphics is coolGraphics is cool

• I like to see what I’m doingI like to see what I’m doing

• I like to show people what I’m doingI like to show people what I’m doing

Graphics is interestingGraphics is interesting

• Involves Involves simulationsimulation, , AI,AI, algorithmsalgorithms, , architecturearchitecture……

I’ll never get an Oscar for my actingI’ll never get an Oscar for my acting

• But maybe I’ll get one for my CG special effectsBut maybe I’ll get one for my CG special effects

Graphics is funGraphics is fun
