Hi Cesium team.
I am a software developer working on a project to generate contents to use in Cesium. We have a performance issue when we load our scene.
I have two simple objs that sharing a simple jpg image. When I generate 3d tile using model tiller. It produced tileset with some b3dm files. Unfortunately, I saw that each b3dm has its own copy of the image inside the glb content. We know that glb files support external referencing like gltf.
Before implementing a post processing that will modify the glbs inside b3dm files to use external referencing, I have two questions.
- Does Cesium render engine support glb external referencing or not? I mean when it tries to load two b3dm files into the memory that they have a similar external reference, does it import the reference two times or only once?
- I know that Cesium for optimisation is generating a texture atlas. In the above case, when it is generating the atlas does it duplicate the same texture or not?
Thanks for your support
