LDS-1 (Line Drawing System-1) was an attached calligraphic (computer graphics) processor with a workstation terminal created by Evans & Sutherland. It was controlled by a variety of host computers. Straight lines were smoothly rendered in real-time animation. General principles of operation were similar to the systems used today - 4x4 transformation matrices, 1x4 vertices... Possible uses included flight simulation (in the product brochure there are screenshots of landing on a carrier), scientific imaging and GIS systems.
The first LDS-1 was shipped to the customer (BBN) in August 1969. Only a few of these systems were ever built. One was used by the Los Angeles Times as their first typesetting/layout computer. One went to NASA Ames Research Center for Human Factors Research. Another was bought by the Port Authority of New York to develop a tugboat pilot trainer for navigation in the harbor.
Famous quotes containing the word drawing:
“Ye whose clay-cold heads and luke-warm hearts can argue down or mask your passions—tell me, what trespass is it that man should have them?... If nature has so wove her web of kindness, that some threads of love and desire are entangled with the piece—must the whole web be rent in drawing them out?”
—Laurence Sterne (1713–1768)
