3D point cloud rendering tools or controls under WPF

problem description

I am now using WPF to develop a 3D scanning software, and now I want to use a control to display the scanned 3D point cloud in real time. I don"t know if there are any good controls or tools that can solve this problem.
ask the gods for advice!

the environmental background of the problems and what methods you have tried

it is known that SCIChart has a control, but the commercial version does not want to use it.
the Viewer3D, that comes with WPF feels a little complicated, and there are many things to set up by yourself, especially the real-time display of this requires all kinds of optimization. At present, there is no energy to do the optimization work
