Document Summary

Itp 101: introduction to information technology, week 3, lecture 1: analog vs digital + computer. --definition: of, relating to, or being a mechanism in which data is represented by continuously variable physical quantities. --definition: of, relating to, or using calculation by numerical methods or by discrete units especially binary digits. 2d graphics models may combine geometric models (vector graphics), digital images (raster graphics), text to be typeset (defined by content, font style and size, color, position, and orientation), mathematical functions and equations, and more. --these components can be modified and manipulated by two-dimensional geometric transformations such as translation, rotation, scaling. 2d graphics software: many graphical user interfaces (guis), including mac os and microsoft windows are primarily based on 2d graphical concepts. 2d graphics editors (drawing programs) are application-level software for the creation of images, diagrams and illustrations. Image editors are specialized for the manipulation of digital images. --an extension of cam (computer aided manufacturing) and cnc (computer numeric control)
