Could you build this?

Partial The web viewer itself is straightforward using open-source WebGL/WebGPU Gaussian Splatting viewers, but capturing and training the high-fidelity 3D reconstruction requires specialized photogrammetry workflows.

What it would actually take: The frontend is easily built using standard libraries like `@mkkellogg/gaussian-splats-3d` or PlayCanvas. The hard part is the capture and data pipeline: capturing thousands of high-resolution, controlled exposure photographs and drone scans of Grace Cathedral, running them through COLMAP for Structure-from-Motion, and optimizing the 3DGS model via heavy GPU training pipelines. Producing the clean, artifact-free dataset requires physical on-site access, photogrammetry hardware, and 3D computer vision expertise.
