Failing to decode JPEG image inside glTF from Metashape #236

Closed ferengi82 closed 4 years ago

Hi, i tried too upload a *.glb file (3D-Mesh from Agisoft Metashape) and got an error. Asset ID 49550.

Thanks for reporting this @ferengi82. Looks like this is a bug on our end with reading the JPEG images in this model.

We'll take a look into fixing this. In the mean time, you can work around this issue by converting your .glb file to .gltf with separate JPEG images (you can do this with gltf-pipeline using the --separate flag), and then re-exporting each image file with any image editing software like Gimp.

I would also recommend choosing 3D Capture as an input type when tiling this on Cesium ion, since this is a photogrammetry model (captured from the real world). You'll get a more optimized 3D Tileset that way.

Hi,

i uploaded the convertet gltf and the re-exportet jpgs. now i get this error

We've encountered a problem with your data:

Error: File Not Found
File: 2019-10-11_Kelheim_Befreiungshalle.bin

If you'd like more help, open an issue in our Github repository or email support@cesium.com with the asset ID: 49723.

That means you didn't upload all the the files needed by the converted glTF (the .bin file contains the geometry). You should see a 2019-10-11_Kelheim_Befreiungshalle.bin in the same directory as the .gltf, so you should upload all those together.

thats embarrassing... thanks, now it worked!

Glad to hear it! I'll keep this issue open so we can look into fixing the problem with the original JPEG images.

We're migrating the issues in this repository to consolidate questions, Cesium ion feature requests, and bug reports on the Cesium community forum, that way there'll be one place to search for answers.

I believe the original issue was resolved here, but if you have any follow up questions please post in the community forum!
