Parisi has designed and developed several international 3D graphics standards. In his early career Parisi worked as a software engineer in Cambridge, MA. From 1987 to 1990 Parisi was at
Bolt, Beranek and Newman, developing scientific and statistical analysis software and managing projects to port products to early graphical user interface systems. From 1990 to 1991 Parisi was a senior software engineer at spreadsheet pioneer
Lotus Development Corporation, where he worked on X, Windows and Macintosh versions of
Lotus 1-2-3. In 1991 he co-founded Belmont Research with BBN alumni, where he created a scientific and statistical analysis software toolkit and wrote the compiler and runtime graphics and user interface libraries for BTL, the company’s domain-specific language for application developers. Parisi was a founding member of the
Web3D Consortium, an organization focused on encouraging development and implementation of open standards for three-dimensional content and services. He was one of the original designers and specification editors of
X3D, an upgrade to VRML which extended its features and added format encodings in XML, compressed binary and JSON.
2012-2023 In 2012, Parisi joined the
Khronos working group creating
glTF, a JSON- and binary-encoded file format for three-dimensional scenes and models intended for web and mobile applications. He served as glTF specification co-editor from 2012 to 2017, and contributed technical features such as the design of the original animation system. Parisi also wrote the initial file loader for
Three.js, and the first sample exporter to glTF from the
Unity game-engine editor. Parisi coined the name “glTF” (Graphics Language Transmission Format) as an alternative to the generic working title “ATF” (Asset Transmission Format), which the working group accepted. Parisi was also instrumental in getting the format adopted by companies such as Oculus and
Microsoft in 2016, which helped propel the format into wide use and industry acceptance. Parisi is the co-host with Mark Pesce of the podcast “A Brief History of the Metaverse.” Parisi authored an introductory book on virtual reality programming published by O’Reilly Media in 2015. ==Bibliography==
