Overlay polygon over gltf 3d


I am having some trouble in a cesium project.
I have this 3D gltf load in the project of a industrial site and I wanna draw a polygon over some empty space of this area, but even with the correct coordinates the polygon doest not overlay the gltf.

Can anyone help me?

I wanna put the black outlined polygon in the empty space between the building.

Hi there,

I’m having a little trouble telling what the intended effect in the image is. Are you sure that your gltf has been positioned such that its over the polygon? Is your polygon clamped to terrain? You may find these examples helpful:

Hope that helps,

hi @dronesmart2017 did you find the solution fo the issue on overlaying polygon over gltf model?

This is now supported! See: https://sandcastle.cesium.com/index.html?src=Classification%20Types.html

The demo overlays polygon to 3dtilesets converted through cesium ion …

The plygon properly overlays on terrian but not on gLTF

here is the sandcastle demo
