Using perspective techniques to extract a 3D model from a painting - in this case a view of London circa 1616. See

Engraving of London (c. 1616) by Claes Van Visscher, in the Guildhall Library, City of London
Both the Swan and Globe theatres, along with the Bear Garden (for bearbaiting), are depicted on the south bank of the River Thames. Topping the entrance gate to London Bridge are the impaled heads of traitors to the crown. In addition to the city’s monuments and houses, Visscher’s work contains scenes of daily life along the Thames—a ship trawling for eels (“The Eell Schipes”), rowboats and barges, carts and cattle in the street, and people strolling and conversing. Windmills occupy the hilltops, and tall ships are anchored in the Pool of London before the yeomen warders of the Tower of London. Many of the prominent structures on the north bank, including Old St. Paul’s Cathedral and St. Laurence Pountney, were destroyed in the Great Fire of London in 1666.
Claes Janszoon Visscher, (1587, Amsterdam – 19 June 1652, Amsterdam), was a Flemish draughtsman, engraver, printmaker and publisher.
Visscher primarily etched and published landscapes, portraits and maps.
Engraving is the practice of incising a design on to a hard, usually flat surface, by cutting grooves into it.
The original Library at Guildhall was founded in the 1420s under the terms of the will of Richard Whittington. Today, it is a major public reference library which specialises in the history of London, especially the City, as well as having other significant collections. The collections held at Guildhall Library are designated as national and international importance.
3D computer graphics
3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.
