<div dir="ltr"><div dir="ltr">Pretty great progress, Don. I'm not sure if I showed this widely earlier, but here's a picture of a mostly vibe-coded app (it struggled early) which shows JSON (not X3D or glTF) rendered with WebGPU: When you edit the JSON, the scene updates automatically! The main problems seem to be that this is not particularly adequate for the archive, since it requires React, Three and Vite. I believe this link is the project, but I may have made some tweaks, especially to the depth and content of the Text node. <a href="https://claude.ai/share/636ed092-ace5-4331-9222-4d0d85e80ada">https://claude.ai/share/636ed092-ace5-4331-9222-4d0d85e80ada</a> (note that you need to press the share/publish button near the top of the web page to publish a project, looking forward to yours!)<div><br></div><div>I do admit I have not tried for "X3D JSON" or "schema validated" yet.
