graphics, and transporter effects, were delegated to a team led by visual-effects supervisor David Takemura. Accustomed to directing episodes for the television series, Frakes was frequently reminded by effects artist Terry Frazee to "think big, blow everything up". Most of the effects sequences were planned using low-resolution computer-generated animatics. These rough animated storyboards established length, action and composition, allowing the producers and director to ascertain how the sequences would play out before they were shot.First Contact was the last film to feature a physical model of the Enterprise. For the ship's dramatic introduction, the effects team combined motion control shots of the Enterprise model with a computer-generated background. Sequence supervisor Dennis Turner, who had created Generations energy ribbon and specialized in creating natural phenomena, was charged with creating the star cluster, modeled after the Eagle Nebula. The nebular columns and solid areas were modeled with basic wireframe geometry, with surface shaders applied to make the edges of the nebula glow. A particle render that ILM had devised for the earlier tornado film Twister was used to create a turbulent look within the nebula. Once the shots of the Enterprise had been captured, Turner inserted the ship into the computer-generated background and altered its position until the images matched up. The opening beauty pass of the new Enterprise was the responsibility of visual-effects cinematographer Marty Rosenberg, who handled all the other miniatures, explosions, and some live-action bluescreen elements. Rosenberg had previously shot some of the Enterprise-D effects for Generations, but had to adjust his techniques for the new model; the cinematographer used a 50 mm lens instead of the 35 mm used for Generations because the smaller lens made the new Enterprises dish appear stretched out. Knoll decided to shoot the model from above and below as much as possible; side views made the ship appear too flat and elongated. Rosenberg preferred motion-control passes of ships over computer-generated versions, as it was much easier to capture a high level of detail with physical models rather than trying to recreate it by computer graphics. For the Borg battle, Knoll insisted on closeup shots that were near the alien vessel, necessitating a physical model. ILM layered their model with an additional five inches of etched brass over a glowing neon lightbox for internal illumination. To make the Borg vessel appear even larger than it was, Knoll made sure that an edge of it
