Hi, thank all.
how can I draw that model like the photo(hexahedral mesh and fill).
Hi there,
I’d recommend creating this model in a 3D modeling program then converting to a gltf for use with Cesium. If you need to make a lot of shapes like this one, you might want to implement a new custom geometry type like this: https://github.com/AnalyticalGraphicsInc/cesium/wiki/Geometry-and-Appearances
hope that helps,
