How to convert large obj to b3dm

CesiumJS
1

hello
I want to convert a large obj file to b3dm.
The obj23dtiles library is converted to a single object, so rendering takes a long time.
I want it to be broken down and optimized for rendering like DJI Terra software
How can I convert obj into b3dm?

thank you

Hi there,

Cesium ion has data pipelines for obj to 3D Tiles.

Hello, thank you for your reply. I already know how to use ionic. The problem is that ionReasource has cost issues because it has not only simple objs but also large objs that scan large buildings. That’s why I want to know how to get an optimized b3dm file for obj.

Can you explain a bit more? Is the problem that ion is a paid service, or are the results you are getting non-optimal?

thank you for your reply.
First, there is an issue with the ion paid service. Because obj capacity is large, if I write code by loading it into myAsset, I have to pay a lot of money. Second, I would like to download a 3D object divided into multiple b3dm, like when output with DJI terra.

Hello, could I ask how you solved this problem? Thank you!

Hi @sunrise,
Thank for your note and welcome to the Cesium community.

Can you expand on which part of the problem you are referring to?

As mentioned before Cesium Ion has data pipeline for obj to 3D Tiles 3D Models – Cesium.

If you would like to download portions of your 3D Tileset in smaller portions, Cesium Ion now offers “clip and ship”. This allows you to download specific parts of your data https://cesium.com/blog/2024/05/08/cesium-ion-clipping/.

Please let us know if this answers your question and if we can be of further assistance.
Best,
Luke
