as you can see in the image below, the massive gravitational energy of the black hole bend the fabric of universe, on of the way to create such a phenomena is to bend the rays that emit from camera to produce something link black hole effect.

are there any vex function or vop node that can manipulate the camera rays in mantra?

I was thinking about creating some curve and assign their tangent attribute to camera rays.

is that possible?

or I can create a fake geometry.
