Get min and max height of Point Cloud

CesiumJS

Hello.

I am going to implement elevation shading for point cloud.

To do this I need min and max height of point cloud to draw shading effect (gradient).

If anyone knows it, please teach me how to get it.

Thanks

I’m assuming you mean you need the absolute min/max, not just from what’s in view. Since this would require enumerating all points, it’s best to do this as an offline process. You could use a tool like Pdal to do this, store this information, and then use it in your CesiumJS scene when shading your 3D Tiles point cloud:
