Visualization
• Visualization is related to vision (seeing through eyes), one of the major
human senses to interact with the world.
• Visualization is the process of forming a visual image of things that can be
seen through eyes (and/or imagined in human mind).
• What can be visualized?
– Visible reality: person, animal, building, mountain
– Hidden reality: earth core, blood vessel, universe
–
Invisible reality: wind, air, heat, electron, sound, smell, magnetic fields
– Abstract entity: data, information, idea, hierarchy, process, relationship
• How to visualize them? – Types/features of visualization forms
– 2D vs. 3D
– Static vs. motion
– Virtual (created in computers) vs. materialized (built/displayed in real world)
– Realistic (using realistic objects) vs. abstract (using abstract shapes)
• The visualization process (and the result) may change the original form of
things, or create new forms, for better unders
