The web content discusses a little web app that demonstrates how to fetch 3D Tiles from the Google Photorealistic API and normalize & rotate the glTF tiles. The purpose of the app is to educate users on how to experiment with the API and adjust parameters like zoom and screen space error. Offline use is prohibited according to Google’s Map Tiles API policies. The app fetches URLs to glTF tiles based on a given lat/lng/zoom level and normalizes them to be centered around (0, 0, 0). The concept of “screen space error” is explained as a measure of level of detail. The content also provides instructions on running the app locally.
