Background
3D’s early beginnings can be traced back to 1962 when Morton Heilig invented the Sensorama simulator. It provided 3D video feedback, as well motion, audio, and haptic feedbacks to produce a virtual environment. The next stage of development was Dr. Ivan Sutherland's completion of his pioneering work in 1968. He created a head-mounted display that produced a 3D, virtual environment by presenting a left and right still image of that environment.
Availability of technology as well as impractical costs held back the development and application of virtual environments until the 1980s. Applications were limited to military ventures in the United States. Since then, further research and technological advancements have allowed new doors to be opened to application in various other areas such as education, entertainment, and manufacturing.

Famous quotes containing the word background:
“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
“... every experience in life enriches one’s background and should teach valuable lessons.”
—Mary Barnett Gilson (1877–?)
“They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.”
—Jimmy Carter (James Earl Carter, Jr.)
