Gaussian splatting model empty

Cesium ion
1

Hi all,

I am developing an app that post photos through the Cesium REST API to produce gaussian splatting models.

The 3D mesh model is reconstructed properly (id:4517707), but the gaussian splatting model presents an empty bounding box on the Cesium ION interface (id:4517706)

If I try to access the gaussian spatting tileset on my frontend, I am getting the following error message :

A 3D tile failed to load: https://assets.ion.cesium.com/ap-northeast-1/4517706/0/0.glb?v=1 Cesium.js:9993:117128
Error: Failed to load glTF

Any hint on how to get the gaussian splatting reconstruction to work would be greatly appreciated.

Thanks for reaching out with this problem. This is an issue that our team recently became aware of and is working to fix. There is an issue in the CeisumJS repository to track this. That issue should have updates when we have made some progress.
