The Graphics Group, which was one-third of the Computer Division of Lucasfilm, was launched in 1979 with the hiring of Catmull from NYIT, where he was in charge of the Computer Graphics Lab. He was then reunited with Smith, who also made the journey from NYIT to Lucasfilm, and was made the director of the Graphics Group. At NYIT, the researchers pioneered many of the CG foundation techniques—in particular, the invention of the alpha channel by Catmull and Smith. Over the next several years, the CGL would produce a few frames of 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 several critical technologies for CG—including particle effects and various animation tools.
