CyArk has launched the America 250 Tapestry Collection, a digital heritage initiative celebrating the nation’s 250th anniversary. The project uses 3D gaussian splatting to recreate three historically significant sites that visitors can explore through a web browser.
This project leverages CyArk’s open-access, web-based storytelling platform, allowing users to experience virtual first-person walkthroughs natively within a web browser without specialized hardware.
The sites include the Revolutionary-era George Wythe House in Colonial Williamsburg, Virginia; the 1926 Rosenwald Historic Russell School in Hillsborough, North Carolina; and O’Hara’s Restaurant and Pub, a post-9/11 sanctuary located near Ground Zero in New York City.
To capture these environments on foot, field teams utilized the handheld XGRIDS PortalCam spatial camera for interior spaces alongside aerial drone sensors for surrounding exteriors.
On the delivery end, the platform relies on advanced infrastructure including the PlayCanvas Engine, World Labs’ Spark.js renderer over WebGPU, compressed SPZ and SOGS asset formats, and Cesium 3D Tiles streaming for real-time performance.
A Faster Approach to Heritage Documentation
“Splats have really changed how we approach heritage documentation. We can capture in a fraction of the time compared to traditional LiDAR and photogrammetry, and we hold onto the reflections, the way light falls, the surface detail that a mesh flattens. For cultural heritage, that’s a lot of what makes a space feel alive.”
Why 3D Gaussian Splatting Matters
This project shows how cultural documentation teams approach data acquisition and user accessibility. Historically, creating detailed reconstructions required intensive terrestrial lidar scanning and photogrammetry workflows, which often struggle with complex light reflections, translucent surfaces, and transparent boundaries. Gaussian splatting captures volumetric radiance fields directly, preserving specular reflections, soft lighting transitions, and subtle surface textures that traditional polygon meshes usually flatten. The ability to capture intricate locations in a fraction of the time compared to standard lidar layouts yields fieldwork efficiencies.
By embedding narrated audio by local interpreters and testimony from historical alumni, the collection transforms into living histories. This helps anyone with internet access to explore physical environments with realistic accuracy.
Implications for the Geospatial Industry
The deployment of the America 250 Tapestry Collection displays many of the current market trends involved in the 3D modeling, surveying, and mapping industries. By successfully integrating WebGPU, compressed splat formats, and streaming tiles, this project is an example that radiance field datasets are ready for large-scale consumer delivery without computational bottlenecks. As geospatial analysis tools and web mapping toolkits rapidly adopt native support for gaussian splatting layers, the boundaries between abstract point clouds and photorealistic representations will continue to blur.
For surveyors and earth scientists, these visualization techniques offer powerful mechanisms to communicate complex stories to stakeholders, clients, and the general public. Ultimately, this integration of rapid field collection, automated processing pipelines, and web-based rendering sets a new baseline for spatial asset management across heritage preservation, construction engineering, and municipal mapping applications.
