ICS 415Dr. Muhammed Al-Mulhem21 The Basics Computer graphics: generating 2D images of a 3D world represented in a computer. Main tasks: modeling: (shape) creating and representing the geometry of objects in the 3D worldmodeling: (shape) creating and representing the geometry of objects in the 3D world rendering: (light, perspective) generating 2D images of the objectsrendering: (light, perspective) generating 2D images of the objects animation: (movement) describing how objects change in timeanimation: (movement) describing how objects change in time Computer graphics: generating 2D images of a 3D world represented in a computer.

Graphics 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 interesting Involves simulation, AI, algorithms, architecture…Involves simulation, AI, algorithms, architecture… I’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 fun Graphics 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 interesting Involves simulation, AI, algorithms, architecture…Involves simulation, AI, algorithms, architecture… I’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 fun
