Mental Images GmbH (stylized as mental images) was a German computer generated imagery (CGI) software firm based in Berlin, Germany, and was acquired by Nvidia in 2007, then rebranded as Nvidia Advanced Rendering Center (ARC), and is still providing similar products and technology.

The company provides rendering and 3D modeling technology for entertainment, computer-aided design, scientific visualization and architecture.

The company was founded by the physicists and computer scientists Rolf Herken, Hans-Christian Hege, Robert Hödicke and Wolfgang Krüger and the economists Günter Ansorge, Frank Schnöckel and Hans Peter Plettner as a company with limited liability & private limited partnership (GmbH & Co. KG) in April 1986 in Berlin, Germany.

The first versions of the rendering software were influenced, tested and used for production by Mental Images' then operating large commercial computer animation division, led by the visual effects supervisors John Andrew Berton (1986–1989), 2000 Academy Award winner John Nelson (1987–1989), and 1996, and 2000, Academy Award nominee Stefen Fangmeier (1988–1990).

In 2003, Mental Images completed an investment round led by ViewPoint Ventures and another large international private equity investor.
