Armed with Digistar from Evans & Sutherland, the lab continues to be on the cutting edge of immersive technology. Working with Vis Lab staff and faculty, students learn to produce and present fulldome content for school field trips, public shows, and Colgate courses.

The Vis Lab will be closed for public showings April 29 through June 3.  We will have special showings during Commencement (May 17-18) and Reunion Weekends (May 30 - June 2).

About the Lab

Robert H.N. Ho
Robert H.N. Ho

The Ho Tung Visualization Laboratory was a special gift to Colgate from Robert H.N. Ho '56 in memory of his grandfather Sir Robert Ho Tung.

Knighted twice by King George V and Queen Elizabeth II, Sir Robert Ho Tung was active as a businessman and philanthropist in the British Crown Colony of Hong Kong. At the September 15, 2007 dedication ceremony for the visualization lab, Mr. Ho quoted a Chinese proverb: "huh shwei, suh yuan"-"Drink water: consider source."

May those who discover new frontiers in this laboratory consider how they can model Sir Robert Ho Tung and Robert H.N. Ho's inspiring words.
