Which tools produce PLY files in practice?

The capture stack: handheld and desktop 3D scanners, drone photogrammetry solvers, depth-camera research code and medical imaging exports. If a device measured a real surface, the odds are good its software wrote PLY — often alongside vendor-specific formats for the same data.

Can a PLY file contain several separate objects?

Technically the format stores one vertex list and one face list, so multi-part scans arrive as a single mesh with disconnected shells. Splitting into separate objects is a DCC-task: import PLY into Blender or MeshLab, select by shell, then export each part on its own.

Why do scans arrive as millions of tiny triangles?

Because the scanner records the surface at instrument resolution with no idea which detail matters. The density is an archive, not a working mesh — decimate it in MeshLab or Blender once you know the target. Converting PLY to GLB here preserves the detail; downscaling is a separate artistic decision.

Is it better to decimate a scan before or after converting it?

After, in a tool built for the job. The converter's job is lossless transport — decimating first would bake a quality decision into the only copy you have. Convert PLY to GLB or OBJ, keep the original PLY as archive, and reduce the working copy to your target polygon budget.

Can I 3D-print straight from a scanner's PLY file?

Yes — convert PLY to STL and the shell goes to any slicer. Two practical checks first: close holes in a repair tool, because scans are rarely watertight, and confirm the scan's scale, since PLY keeps real-world units but slicers love to second-guess them.

About the PLY format

PLY is the format of things that were measured, not modelled. Scanners, photogrammetry solvers and depth cameras write it, because it stores what those devices actually produce: a dense shell of triangles, frequently with a color value pinned to every vertex. There is no hierarchy, no materials in the PBR sense, no animation — just the captured surface, preserved with metric fidelity. That makes PLY the archival format of the scanning world and the starting point for every cleanup, decimation and retopology pass that follows.
