Gpu post nr 2
A little machinery behind this page: video, photo, 3D scan and point cloud.
What loaded
Open a view to see what actually loaded.
Videos
The standard path is MP4 because it works almost everywhere. Some posts also have adaptive playback when you want the heavier route.
A poster keeps browsing light. Opening the video is the signal to spend more bytes.
HLS · MPEG-DASH
Photos
Small first. Sharper AVIF, WebP, or JPEG when the browser and screen can use them.
The fallback is just an image. That is the point.
AVIF · WebP · JPEG
3D scans
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.
The first look, normal model, and heavier files 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.

Why choices exist
One file does not fit every screen and connection. Browse stays light; inspect spends more when you ask.
