Is the wise man named Pong or Phong?
Phong, and his favorite game is Pong. Both became big names in computer graphics in the early 1970’s. Pong, created by Atari, was the first successful coin-operated video game. Mathematician Phong Bui-Tuong described a better method for shading polygons in the CACM in June 1975. His method produces more realistic images than Gourand shading.
