This tool converts COLLADA models to glTF for use with Cesium. Create a zip file with your COLLADA file (.dae) and any images it references. Then, drag and drop the zip below. It will be uploaded, converted to glTF, and then a new zip will be downloaded containing the glTF model.
Although models are deleted after they are converted, please do not upload proprietary models.
Tip: If a COLLADA file doesn't reference any images, the .dae file can be dragged and dropped without creating a zip.
For troubleshooting and details on how to use the Cesium API to load glTF models, see the 3D models tutorial.
