Is there a way for ArcGIS runtime for .Net to load point cloud programmatically rather than .slpk file?

Hi, I have thousands of self-defined Lidar data points, each one is defined by latitude, longitude, and altitude as GIS position and a float value as concentration (to be render by different colors in 3D map). These real-time data is collected via some ground-based laser radar and to be displayed synchronously in esri:SceneView, a WPF application, exactly like this:

I spent a couple of days studying here: https://github.com/Esri/arcgis-runtime-samples-dotnet, but these samples should load point cloud from some '.slpk' file.

I am not planing to be an expert in GIS, what I want to know is: is there a way for 'ArcGIS Runtime for .Net' to create these points programmatically rather than slpk file?
BTW, my application is a desktop one with no server or portal.

Any suggestions? Thanks in advance!

If we cannot use ArcGIS runtime to programmatically create point cloud, is it possible to create a slpk file programmatically ?

Well, it is seemingly possible: point_cloud_scene_layer_structure, only doubt it is feasibility... 😞
Probably I should give it up...

No there isn't. The SLPK is heavily indexed so that it is possible to handle and render billions of points, even on lower end device - a lot of preprocessing goes into that, so it won't run real-time.
