3D models
Most models here come from photogrammetry: overlapping photos solved into a textured mesh. The browser gets GLB files, rendered posters, lighter and fuller model choices, saved camera framing, and source-format notes where they matter.
Texture compression is treated as real delivery proof, not a label. If a model has ordinary WebP textures, it is described that way until an actual KTX2/BasisU asset exists and is served correctly.

Point clouds
A point cloud is a 3D scene made from many individual points, often with colour, rather than a solid surface. It is closer to a floating swarm of measured dots than a normal 3D model.
PLY is one common source file format for that kind of data. Public viewing works better when the cloud is converted into streamable tiles, because the browser can load nearby detail instead of swallowing one huge raw file.

Why the variants exist
Browsers, screens, networks, and media types do not agree on one perfect file. The page stays simple, while the saved asset details keep source kind, quality level, preview confidence, dimensions, format, and fallback intent.
Each asset gets the special handling it needs. The goal is not to show off file formats; it is to make the page choose the right thing quietly, then explain the machinery only when you ask.
