Vector Graphics Use Functions

Lesson Focus 
For a half century computing technology has played an increasing role in how we create visual imagery. Vector graphics was the original method for rendering images on a display screen. It fell out of favor in the 1990s as increasing memory size allowed raster, or bitmap images, to be stored. Within the last decade there has been a resurgence of vector graphics to efficiently support graphic displays as large as billboards and as small as postage stamps. Vector graphics are dependent upon functions. This lesson introduces vector graphics and functions through a collaborative design activity.

Age Levels:

14 - 18
Objectives 
Introduce students to:
  • how vector graphics technology works, and contrasts with raster graphics.
  • how smooth scaling occurs.
  • the role that functions play in vector graphics.
  • how modern mapping software is implemented as vector graphics.
Anticipated Learner Outcomes 
Students will:
  • describe the difference between vector and raster graphics.
  • create a vector image by hand and write the related functions.
  • draw an personal logo using a set of functions.
  • explain how mapping software is more flexible with vector graphics.
