It's a great tool for model convert to cesium, i want to know the tool is support to create LOD whether or not

You can find LOD sample data in there, which gives you an idea to implement LOD in 3D Tiles.

After you understand it, you can make LOD tileset by following steps :

• Export .obj models with different level of detail.
• Use obj23dtiles convert them to .b3dm.
• Create or modify a tileset.json file follow sample data's tileset.json file.

I hope this is clear enough.

@PrincessGod Can you tell us how to generate different LOD model out of single obj file? I couldnt find suitable application to do this. Any lead in this would be helpful

Sorry, I am not familiar with 3D modeling software (๑˙ー˙๑)

Hello @skylning and @ManishSahu53 , I just create an online tool to tile big single model into 3D Tiles with Level of Detail
http://www.3dtiler.com/
If you want to tile your model which is bigger than 20MB(current upload limit), you can send me the file and I can tile it manually.

Hi @CrashedBboy . I just tried you converter with an gltf file. I think the model is converted but the when I tried to download the converted 3dtile, the server respond with 500. Here's the download link http://www.3dtiler.com/tiler/3dtiles/iv7elle68p2ofsnl. BTW. I am working on my own open source 3dtile converter with vcglib's "quadric error method" to simplify mesh. Normally it's ok. But when there are many small meshes in the scene. This simplification method cannot merge the as one(Which I think it should). Do you have any experience in that if you don't mind to share?

hi, could you explain a little more how to do this ?

您可以在其中找到 LOD 示例数据，这为您提供了在 3D Tiles 中实现 LOD 的想法。

理解之后，就可以按照以下步骤制作LOD瓦片集了：

• 导出 .obj具有不同详细程度的模型。
• 使用 obj23dtiles 将它们转换为.b3dm.
• tileset.json按照示例数据的文件创建或修改tileset.json文件。

我希望这足够清楚。
