First human and CGI character interaction, first live action reflection on on CGI character, first reflection mapping
1) The NYIT (New York Institute of Technology) staff, most notably Gene Miller, Lance Williams and Michael Chou, were responsible for an innovative rendering technique called "reflection mapping", which was used to provide realism to shiny objects in television and the movies (Flight of the Navigator, and The Abyss). One of the first such videos was done by Chou, showing girl standing next to a shiny synthetic robot and kissing him. NYIT published the technique at SIGGRAPH in 1982 and 1984, and in 1985 used the technique in this short video.
2) Reflection mapping later used in Terminator 2 for T-1000 robot.
