I have found out, that the attributes are stored in the b3dm-File for each node at nodes->extras, but how do I access these values with the functions for Cesium.Cesium3DTileFeature or are there other other possibilities? I think the point is, that i need to create Features from my model…
You can reach out to sales@cesium.com and they’ll set you up with an evaluation.
Being able to read metadata like this from glTF is definitely something we want to officially support. One issue is that there isn’t currently a standard for how to embed this data, so I’m curious to hear more about your process here. Were these long/lat’s originally from the shapefile? Did you use any Blender plugins for importing this?
Yes, I have imported a shapefile with its geometry and the attributes into Blender with the included GIS-Import and exported it as glTF. In the glb-File they are kept as JSON, but i guess the pipeline of 3d-titles-tools doesn’t recognize the structure how they were stored in the glb file.
