3D Tiles Generator

3D Tiles
1

Hi,

I have a 3D model in OBJ format with separate texture files. I created a Cesium Ion account, zipped the model, and uploaded it. After the tiling process was completed, the model was optimized for rendering in Cesium Ion.

I’m looking for an open-source implementation or reference for the tiling process used by Cesium Ion. The closest tool I’ve worked with is Obj2Tiles from OpenDroneMap, but it generates the same number of tiles per level of detail (LOD), which differs from Cesium Ion’s approach.

Is there any publicly available code or documentation explaining the exact algorithm Cesium Ion uses to generate and optimize 3D tiles? Specifically, I want to understand how it determines LOD levels and efficiently structures tiles for rendering.

Any guidance or references would be greatly appreciated!

There is no open source implementation like tiling process used by Cesium Ion as I know.
That is why you need to purchase their tiling tool.
