How to display 3D building with texture from arcgis in cesium?

Hello, I am a newbie here.
Could you please help me,I have a 3D buildings with texture made in Arcgis and Sketchup and I want to display them in cesium.

  • I want to know in which format can I convert this model to be displayed in Cesium?

Thank you

You need gltf format.
Look at this converter page to convert a Sketchup model from COLADA to gltf format.

Hi Left,
Thanks for getting back to me. I converted the COLLADA file to gltf and it works, but since I have many 3D building models, do I have to change the value of modelMatrix for each model?

I don’t know, I think the answer is yes. I’m only a little ahead of you on the learning curve for Cesium, there aren’t many people coming from ArcGIS background, like us. I’ve seen reference to an off-line batch converter, which might help process many models, but I’m not sure what the solution is to your modelMatrix q. I may need to deal with this in the future, and I’m curious what the answer is, if someone else in the cesium-dev forum can help you
