Draw 3D ground in different colours as in the example

Hello everyone, I’m trying to implement a similar functionality:

To paint the floor around some prim, or at a certain lat and lon. For example, I create a prim on a 3D tile and a circle will be created around it within a certain radius, which visually paints the ground (i.e. part of the 3D tile)

Link on example from Cesium JS

In the example above, it is already implemented in Cesium JS, could you tell me how to implement it in Omniverse? I haven’t found any tutorials or documentation on this. Thank you!
