How to render layers on the facade of a building in 3dtitles

CesiumJS

Currently, I want to add a layer to a specific area on the building in 3dtitles, and the layer should be an RGB grid generated according to certain rules. How can I do this

Hi @supershunan, welcome to the community!

Can you explain a little more what you mean by a “RGB grid”?

I can think of two possibly relevant approaches:

  1. Draping imagery on 3D Tiles. This is a relatively new feature in CesiumJS, which you can read about in Draping Imagery over 3D Tiles in CesiumJS – Cesium.
  2. Classification of 3D tiles, overlaying a color in an area defined by a polygon. You can read about this in Dynamically Annotating 3D Tiles in CesiumJS – Cesium

Both of those articles include Sandcastle links with working code examples.

Let me know if I misunderstood what you are trying to do.
