PLY File Not Rendering in Scene Despite No Errors – Possible Material Issue

[Gemstone-t]

Discussed in #394

^{Originally posted by Gemstone-t December 16, 2024}
I am encountering an issue when trying to load a PLY file into my scene. The file loads without any errors in the console, but nothing appears in the scene. I have confirmed that the PLY file can be successfully opened and viewed using 3D Viewer, so the file itself seems fine.

I suspect the issue might be related to the lack of material or color information in the PLY file, which could be why nothing is visible.

Could someone please help me resolve this issue? I would appreciate any guidance as soon as possible.

Could you share the .ply?

I use the ply files from "https://www.artec3d.com/3d-models/ply"

These don't contain the proper data (no splats)

ply

So, is it possible to show this file using Gaussian Splat 3D?
I am currently loading and displaying the file with PLYLoader in Three.js, where I apply the material to the PLY geometry. Is there a way to set the material in Gaussian Splat 3D in a similar manner?

All ply parsers have 'x', 'y' and 'z', but require the other props to be present (INRIAV2PlyParser.js) as expected/needed :) The viewer offers a toggle between splats/points, still the point representation is based on splat props.

Is it impossible to show like these PLY files by using GaussianSplats3D.Viewer?

[seppestaes]

Yes, I believe so.

Thank you for your help.

I'm just an enthousiast of this repo :)
