Open 0xr.space in the Quest browser or on a computer, press Open and choose the .pcd. ASCII, binary and binary_compressed files all open, the last being what PCL's savePCDFileBinaryCompressed writes. Each point is drawn as a small round dot in its packed rgb or rgba colour, sized to the cloud's spacing, and on a headset you can walk through it.
Only x, y, z and rgb or rgba are read. Intensity, normals and labels are not shown, so a cloud without rgb is white. The axes are used as written, with Y up, so a cloud saved Z up opens on its side, and a cloud far from its origin is moved to its own centre. A Quest draws up to 500,000 points at once and a computer 2 million. A cloud cannot be shared or downloaded yet.
Yes. The LZF compression PCL uses is unpacked in the browser, field by field.
It has no rgb or rgba field. Intensity is not turned into shading, so every point is white.
A Quest draws at most 500,000 points at once, a computer 2 million. A cloud with more keeps that many. Crop it for more detail.
Not yet. A point cloud stays on the device it was opened on.
No. It is read on the device, with nothing installed and no account.
