Procedural 3D Modeling for the Geospatial World
Workshop at the Savannah College of Art and Design
Our Work

What We Do

Our mission is to empower geo-enabled professionals, students, and architecture/design and planning firms by teaching a 3D modeling and visualization process using ArcGIS CityEngine and the Epic TwinMotion rendering app. We believe that mastering these tools leads to expanded opportunities, broader career paths, and improved client/public collaboration.

This process and its visually stunning results are illustrated in the Esri video Urban Design Visualization with ArcGIS CityEngine and TwinMotion. Also see our video example below, produced in CityEngine using Esri procedural rules and finished/rendered in TwinMotion 2024.1.

Classroom and Video Instruction

We conduct workshops, participate in design/planning classes, and offer remote individual guidance for anyone interested in learning this process. Our instructional series, “CityEngine from the Ground Floor Up,” is available on YouTube to complement classroom learning.

Currently, we are also seeking partnerships with planning firms and agencies to validate our work processes and assess the demand for these services.

Our Work

We have been involved with CityEngine since its 2014 version. A significant portion of our work has been dedicated to writing CGA (Computer Generated Architecture) rules, the programming language that CityEngine uses to create 3D buildings, streets, and urban landscapes. We pushed the boundaries of CGA by developing rules to generate some of our favorite structures, such as bridges and “supertall” buildings. This high level of complexity made more typical challenges seem much simpler. Our work’s visual quality significantly improved when we started using Epic TwinMotion in 2023, a relatively simple tool that is relatively simple to learn and delivers fast results


About Us

JeffCity Geo+Media is me, Jeff Herzer. I began my career in broadcast journalism and later, worked as a digital media producer at a national architecture/engineering firm in Kansas City. There, I met some incredibly talented 3D modelers who produced content for our digital media productions, supporting public outreach for the firm’s major public transportation projects.

Since then, there have been significant advancements in the field, allowing individuals with geospatial skills to aspire to this type of work. It’s remarkable how the state-of-the-art has evolved over 25 years. I never imagined I would one day be producing 3D content that would surpass the work I saw many years ago. This is why I want to pass the knowledge to others.
