Geometry-based Graphics
•Geometry-based
graphics applications store mathematical descriptions, or “models,” of geometric elements (lines, polygons, polyhedrons…) and their associated attributes (e.g., color, material
properties).
–Example 2D geometric programs: Adobe Illustrator, Macromedia Freehand, AutoCAD and other CAD software.
