I want to use Cesium’s model articulation animation, as in the CZML example. What kind of model editor can be used to create AGI\_articulations animations?Thanks a lot。

You can read about this extension here: [https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Vendor/AGI\_articulations#agi\_articulations](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Vendor/AGI_articulations#agi_articulations).

The only editor I’m aware of that supports it is STK: [https://www.agi.com/products/stk/easily-create-model-articulations-with-stk-plugin](https://www.agi.com/products/stk/easily-create-model-articulations-with-stk-plugin).
