how to make a simple interactive system?

I want to implement a simple interactive system, which looks like Demo video, I use a deep learning model to handle physics(including collision), when I drag the ball, it loads the deep learning model and compute the new vertices of the updated bunny. All the computing is done in gpu and maybe a computing shader or cuda is appropriate. I’m new to UE, how can I start this or is there any tutorial or project which looks like this. thanks.
