Two techniques for creating and animating objects combine computer graphics with real-world elements. In one technique, artists and production technicians build fiberglass or clay sculptures and scan them into the computer. The computer translates the data from the scan into a digital model. The model is then painted and animated in the computer. In the other technique, developers use actors along with animators to create some action sequences.
Actors perform motions with sensors attached to their bodies.
The sensors record their positions. Artists use the data to animate computer characters. This motion-capture method is most often used in sports games. Background artist or modeler. When players find themselves on alien planets, theme parks, football stadiums, or other settings, they have background artists to thank for the view.
