About GPU Raycast

Hello, I am looking for a LiDAR simulator.
I am looking to run Raycast with GPU.
I guess I need to use CUDA in c++ or have knowledge of Compute Shader to achieve this.
However, I have no knowledge of both.
Can someone please give me the information I need to fire Ray on GPU.
I am looking forward to your reply.

Thanks for sharing this very interesting article!
This article explains the use of shaders to implement ray tracing, correct?
I found this article to be very valuable and more informative than the Unreal Engine reference.
Thank you so much.
