Purpose of Computer Graphics

 

 

·        Communicating information with presentation graphics eg charts. Spreadsheets can generate charts needed.

 

·        Visualisation includes simulations, animations, 3D graphics and rendering drawings. Virtual reality demonstrates the potential for graphics visualisation.

 

·        Illustration software consists of paint and drawing programs.

 

·        Charts should be simple, avoid clutter and use a true scale. Charts used by businesses include organisational charts, Gantt charts and flowcharts. A Gantt chart keeps track of projects, showing a timeline for completion of tasks.

 

·        Diagrams include engineering, building and landscape drawings. CAD programs allow easy editing, different views and re-usable objects.

 

·        Animation includes video games, simulation, television commercials and special effects for movies. Morphing is a special effect changing one image to another gradually. Computer animations can help juries visualise  complex topics.
