How to create a curved grid? (like a spacetime grid)

Question

Hello! I'm trying to draw a curved spacetime grid on a plane. Somet$$anonymous$$ng like t$$anonymous$$s: alt text

So far all i got working is an endless grid using a shader i found here: http://forum.unity3d.com/threads/wireframe-grid-shader.60071/

And t$$anonymous$$s is how it looks right now:

Now I need to make it look curved, and the curvature should follow the objects moving on the X,Y plane. How can I get that curved look? Where should I start looking? terrains or transforming a mesh?

Thanks for any help!

@Pica hi, have you done your project? It seems its 3 years ago though. I'm working on similar project. Do you have an end result? Or do you have any suggestions like using shader based grids or texture based grids which one is better? I have unreliable result using shader based grids though. Do you have a ny suggestions or anything to share?
