Mental Images GmbH (stylized as mental images) was a German computer-generated imagery (CGI) software company based in Berlin, Germany. In 2007, Nvidia acquired the company and rebranded it as the Nvidia Advanced Rendering Center (ARC). The company continues to provide similar products and technology, offering rendering and 3D modeling technology for entertainment, computer-aided design, scientific visualization and architecture.
The company was founded in April 1986 in Berlin, Germany, by the physicists and computer scientists Rolf Herken, Hans-Christian Hege, Robert Hödicke and Wolfgang Krüger as well as the economists Günter Ansorge, Frank Schnöckel and Hans Peter Plettner. It was established as a company with limited liability & private limited partnership (GmbH & Co. KG). The Mental Ray software project was initiated in 1986. The first versions of the rendering software were influenced, tested and utilized by the then-sizable commercial computer animation division of Mental Images, which was led by the following visual effects supervisors: The 1991 and 1993 Academy Award winner John Andrew Berton (1986–1989), the 2000 and 2017 Academy Award winner John Nelson (1987–1989), and the 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. Since December 2007, Mental Images GmbH has been a wholly owned subsidiary of the Nvidia Corporation. The company is headquartered in Berlin with subsidiaries in San Francisco (Mental Images Inc.) and Melbourne (Mental Images Pty. Ltd.) as well as an office in Stockholm. Following its acquisition by Nvidia, the company was renamed Nvidia Advanced Rendering Center (Nvidia ARC GmbH).
