third of the Computer Division of Lucasfilm that was launched in 1979 with the hiring of Dr. Ed Catmull from the New York Institute of Technology (NYIT),[6] where he was in charge of the Computer Graphics Lab (CGL). At NYIT, the researchers pioneered many of the CG foundation techniques—in particular the invention of the "alpha channel" (by Catmull and Alvy Ray Smith);[7] years later the CGL produced an experimental film called The Works. After moving to Lucasfilm, the team worked on creating the precursor to RenderMan, called REYES (for "renders everything you ever saw"); and developed a number of critical technologies for CG—including "particle effects" and various animation tools.
