Parisi worked with such corporations as Microsoft, Netscape, Silicon Graphics, Sun Microsystems and Sony to gain industry acceptance of the new protocol as a standard for desktop virtual reality.

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.

[13] 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.

[14] 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.

[15] 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.

[17] With the rise of consumer virtual reality and in the wake of Facebook’s acquisition of Oculus, Parisi advised several startup companies and became a public speaker and consultant.

[10][9] From 2011 through 2014, Parisi wrote books, created training courses and consulted to companies on WebGL, the standard JavaScript API for rendering interactive 2D and 3D graphics in web browsers.
