Frequently Asked Questions

Will the glTF to PLY conversion preserve all geometry?

The conversion preserves vertex positions and face connectivity. However, PLY doesn't support glTF's advanced features like materials, animations, or scene hierarchies.

Can I convert animated glTF files to PLY?

PLY is a static format, so only the base geometry from the glTF will be converted. Animation keyframes and skeletal data are not included.

Does the conversion handle glTF materials and textures?

No, PLY format doesn't support materials or textures. Only geometric data (vertices and faces) is transferred to the PLY file.

Are there file size limits for glTF to PLY conversion?

The conversion runs in your browser, so very large glTF files (>50MB) may be slow. Most web 3D models convert quickly without issues.

Can I convert glTF 2.0 files?

Yes, the converter supports both glTF 1.0 and glTF 2.0 formats, automatically detecting the version and extracting geometry data.

Will vertex colors be preserved in the PLY?

Yes, if the glTF contains vertex colors, they will be included in the PLY file as color properties for each vertex.

Does the conversion work with binary glTF (.glb) files?

Yes, the converter handles both .gltf (JSON) and .glb (binary) formats, extracting the same geometric data to PLY format.

Can I convert multi-mesh glTF scenes?

The converter combines all meshes in the glTF scene into a single PLY mesh. Individual mesh separation is not preserved.

Will the PLY file work in research software like MeshLab?

Yes, PLY is widely supported in research tools. The converted file will work directly in MeshLab, CloudCompare, and other mesh analysis software.

Does the conversion preserve the original scale and orientation?

Yes, vertex positions are preserved exactly as defined in the glTF coordinate system. No scaling or rotation is applied during conversion.
