Alain Chesnais

Alain Chesnais (born 21 September 1956) is a French computer scientist, entrepreneur, and community leader in computer graphics. He is considered a defining figure of the third generation of CGI pioneers, the group that brought 3D graphics into mainstream use. Chesnais is best known for his key role in developing Maya, one of the world’s most influential 3D animation platforms. He served as President of ACM SIGGRAPH between 2002 and 2005, and as President of the Association for Computing Machinery from 2010 to 2012.

Early life and education Alain Chesnais was born in Saint-Cloud, near Paris, in 1956. In 1958 his family emigrated to New York City. which introduced a formal model of concurrent database access and proposed an approximate analytical solution to evaluate system efficiency.

Early career CNRS and the Centre Mondial Informatique In 1981, Chesnais joined the CNRS as a researcher, focusing on performance modeling in distributed systems.

Studio Base 2 In 1986, he co-founded Studio Base 2 with Nicole Croiset. There, they developed the efficient ray-tracer Camil Tracer, available on PC, Mac, and Unix platforms. This was later acquired by Abvent and became the basis for the Artlantis engine.

Alias|Wavefront and Maya He advised during Thompson Digital Image's acquisition by Wavefront Technologies and later joined their Paris office.

In 2010, he was elected ACM President, serving from 2010 to 2012. He was the first president from the computer graphics field and the second from outside North America.

LEGO Alain

In 2013, at SIGGRAPH, he was gifted a custom 3D-printed LEGO figure in his likeness called LEGO Alain. It has since accompanied him to conferences, appearing in thousands of photographs and becoming an emblem of mentorship within the graphics community (> pictures to date).

Legacy Chesnais’s career spans theoretical computer science, graphics software development, entrepreneurship, and community leadership. He is celebrated for his technical vision, especially Maya, and for helping expand ACM and SIGGRAPH’s global reach, mentoring successive generations of technologists.
