}Geometry-based
graphics applications store mathematical descriptions, or “models,” of
geometric elements (lines, polygons, polyhedrons…) and associated attributes
(e.g., color, material properties). Elements are primitive geometric shapes,
primitives for short.
}Images created as pixel arrays (via sampling of geometry) for viewing, but not stored as part of model. Images of many different views are generated from same model
