3D models
Most 3D views come from photogrammetry: photos turned into a textured mesh. The page starts from a saved camera angle so the object opens in a readable pose.
Lighter and sharper model rungs are separate. Texture labels only appear when that format is actually published.
glTF and GLB · KTX2 textures
Point clouds
A point cloud is the scene as many colored points instead of a solid mesh. It is good for seeing what the reconstruction actually measured.
Public clouds use streamable tiles when available, so the browser loads the part you are looking at instead of one huge source file.
PLY file format · Point Cloud Library
Photos
The page starts with the smallest useful image, then upgrades to sharper AVIF, WebP, or JPEG variants when the browser and screen can use them.
The fallback stays ordinary on purpose: older browsers still get a real image, and better displays can ask for wider-gamut or experimental HDR files when those exist.
AVIF · WebP · JPEG
Videos
The standard path is MP4 because it works almost everywhere. Some posts also have DASH for adaptive playback, controlled from Media settings.
A poster keeps browsing light. Opening the video is the signal to spend more bytes.
HLS · MPEG-DASH
Why there are choices
There is no single perfect file for every screen, browser, and connection. Browse stays light; inspect spends more only after the page has a reason.
These details show what the page can actually load, so the controls stay honest.
