How to interact with point cloud data in cesium.


I am new to cesium and still exploring this.
I want to find out how do i capture a single point in point cloud data and modify it by zooming and rotating. I am using cesium version 1.48.0.
I will appreciate if anyone can help me with this.

Basic code from cesium demo for point cloud data:

var viewer = new Cesium.Viewer(‘cesiumContainer’);

var tileset = new Cesium.Cesium3DTileset({ url: Cesium.IonResource.fromAssetId(5714) });

I aim to enable user to add primitive objects like like cubes, spheres to the 3D scene rendered in cesium

If you just want to enable the user to add objects, you can listen for an input action and create objects, like in this drawing example:

If you want to edit the point cloud itself, the easiest way I can think of is to use the 3D Tiles Styling language, where you can change color/hide points by certain attributes as in this example:

So for example, you could hide points with styling and create new ones that the user can manipulate. You should be able to use the viewer.scene.pick ( function to get what’s under the mouse, like in this example:

Let me know if this helps. Feel free to share more about what you’re building here, it sounds like an interesting application!
