Is there any difference between get_rays() and get_rays_np()

Hi, thanks for the great work!

Is there any difference between get_rays() and get_rays_np()?

Thanks!

Functionality of both functions is same. However, get_rays is implemented using numpy and the resulting variables are stored in cpu. On the other hand, get_rays_np is implemented using torch and load the variables in gpu.
This is my understanding of these function.

I think get_rays_np is the function implemented using numpy
