Join us in building the core technology platform for the future of 3D geospatial!https://cesium.com/careers/

CreateAccess is a nonprofit to help boost socioeconomic mobility through exposure education to 3D creation to enable the next generation of entrepreneurs and creators.All education content is freely available; tailored to beginners; uses modern professional 3D tools; and organized into digestible microcourses where participants achieve quick results and gain confidence.CreateAccess is inspired by my late parents. While it took our family multiple generations of hard-won lessons to see a world where we can dream big, take risks, and create outsized impact, we hope that CreateAccess closes this gap for many families and inspires participants to create the next Cesium.

The idea for the forum was actually first discussed on Episode 2 of our podcast: https://cesium.com/open-metaverse-podcast/open-standards-governance/

Co-creator of glTF, the open-standard for efficient transmission and loading of 3D scenes and models.Former Chair of the 3D Formats Working Group.Navigated glTF community and ecosystem through an enormous growth phase with broad industry adoption and collaboration from large players, including Microsoft, Unity, Google, and NVIDIA, while maintaining the grassroots open-source foundation. There is a vibrant ecosystem of 1,000's of rendering engines, content creation tools, and pipelines supporting glTF.Received the "Khronie" award in 2019 for outstanding contributions to open standards.Spec co-editor for glTF 1.0 and glTF 2.0.

First Day Entertainment builds AI-powered games and is co-founded by my former student, Stephen Zhen Gou.

Zoo builds a modern developer platform for hardware design with first-party applications for Modeling, Text-to-CAD, and 3D CAD Diffs.

Voracious reader and lifelong learner.Authored, edited, or contributed to over ten books on mapping, computer graphics, and games, including:* WebGL Insights editor. Also available free online with over 20K downloads and translated to Japanese.* OpenGL Insights co-editor. Also translated to Japanese.* 3D Engine Design for Virtual Globes co-author. Also translated to Chinese.* OpenGL Insights and the Virtual Globe book were selected to to be included in the Humble Book Bundle: Computer Graphics by CRC Press with over 13K readers.* Reviewed every last word of Real-Time Rendering 4th edition. :)* Rendering section editor for GPU Zen 2.* Contributing author to GPU Pro 4, 5, and 7.I have presented and organized sessions at countless conferences, such as SIGGRAPH, GDC, and FOSS4G, on topics ranging from the open metaverse to autonomous driving to 3D geospatial to WebGL to glTF to education.I've also served on committees for conferences and journals such as SIGGRAPH Asia, I3D, JCGT, FOSS4G NA, and FedGeoDay.Self-taught graphics developer starting in 8th grade with QBASIC. Developed countless 2D games throughout high school in the days of BBSes and 320×200 256 color displays when everyone was writing their own software rasterizers just before commodity GPUs. Developed in Turbo Pascal, x86 assembly, a bit of C, and...yes...Visual Basic.I have a geek-centric website that hasn't been updated since 2017: https://pjcozzi.github.io/---Active martial arts student. Lifelong training in boxing. Former assistant and volunteer at the storied Upper Darby Boxing gym, where I trained at-risk teens in the Backstreet Redemption program and taught classes. I’ve spent countless rounds in the ring sparring with novices to amateur champions to folks who turned pro. That was a long time ago; don’t give me too much credit.

Taught second-year graduate course, CIS 565: GPU Programming and Architecture, nine times. Starting unofficial course advising in Fall 2019. ~200 total students.This is perhaps the most well-known course of its kind with strong ties to industry, especially the WebGL community, Google, NVIDIA, and Microsoft. It is also considered the hardest course in our graphics programs and sometimes the CIS department.Advised a wide array of master thesis, senior design, and independent study projects on topics including open source, spatial data structures, ray tracing, physically-based rendering, image-based lighting, voxels, virtual reality, and glTF. Supported students in creating valuable open-source projects such as the WebGL 2 Samples Pack and glTF Pipeline.Various guest lectures on graphics and open source at MIT, Harvard, Drexel, Williams College, and Penn.My former student and colleague, Shehzan Mohammed, is now teaching CIS 565 and taking it to new heights.

Spun out Cesium into a growth-oriented venture-backed startup. Raised 5M Series A.Started Cesium, the 3D map platform. Grew team to 13, downloads to 500K+, and the open-source contributor community to 180+.Started 3D Tiles for streaming 3D geospatial datasets. Guided it through the OGC Community Standard process and broad adoption.Built partnerships in key verticals.Contributed across most facets: Product strategy. Engineering leadership. Business strategy. Partnerships. Go-to-market. New markets. Business development. B2B & B2G. Open source and open standards community and ecosystem building. Outreach. Recruitment, interns to executives. Mentoring. Team and culture building. IP portfolio. Startup and spinout formation. Series A venture fundraising and equity financing...Before Cesium, held leadership and individual contributor roles in product development using C++ and JavaScript.

For my final internship during undergrad, I returned to IBM and was fortunate participate in their high profile Extreme Blue program, which had a 2% acceptance rate.Our team of 3 technical interns and an MBA student worked with mentors at the Almaden Research Lab to develop a content-addressable storage solution for efficient storage of write once read many data.I developed the frontend using C++ and MFC. We were also issued a patent for secure removal of objects from disk storage.We demoed our work to Sam Palmisano, IBM CEO at the time. I barely knew what a CEO was at the time, and I had no idea I would become one - of a much more modest company - 16 years later.Extreme Blue was very well ran and instilled an innovative, fast paced, collaborative, go big culture. This had a huge impact on the Cesium culture of today.

My second internship during undergrad was at a company I aspired to work at: IBM.I spent the first half developing internal tools for automated component testing of new operating system APIs using Rexx and C. Some of our work was even published in an IBM Research Disclosure.The commitment to testing I learned during this time carried with me to this day and has significantly impacted the Cesium culture and engineering approach.During the second half of this internship, I was thrilled to work with the Linux Kernel (2.6 IIRC) deep in the filesystem layer, focused on caching and virtual machine shared access. I wrote a lots of internal developer guides and loved every minute of the low-level C coding and operating system data structures and algorithms. I had the privilege to work with great mentors who opened up my eyes to the people side of software development while I also read many classic books on the subject: Peopleware, The Mythical Man-Month, etc.

It was an honor to land an internship at my dream company when I was just 18 years old after my freshmen year of undergrad.As part of the System Validation and Software Tools group, I developed internal tools for bug tracking (waaay before GitHub) and front-side bus test tracking using Visual Basic and SQL Server. I even had the privilege to serve as tech lead for a 3+ person team of full-time teammates; to interview my replacement intern; and to dabble in C and inline x86 assembly to optimize test execution.Separate from this internship, during this time I also wrote my first "published" technical articles: an introduction to pointers in C++ series for the CodeCraft newsletter.
