(Anaglyphs: 1853 until
today)
Stereoscopic process
developed by Louis DUCOS DU HAURON in 1891.
The
stereoscopic process is the combination of two different angles
of a geometrical figure with a different color, blue and red,
or green and red, for each angle. Two
transparent screens in the same colors (complementary colors)
than the built planes create the 3D effect.
