Create a box with irregular top and bottom surface

Questions
1

I found some dynamic underground example but geological pieces. It’s something like a box with dynamic generated top/bottom “curved” surface rather than plane.
I found an interesting pg https://playground.babylonjs.com/#8R809X#0 which really similar to the above requirements.
It works for its topmost curved surface but the bottom one. I have tried but not done it.

Any clue or examples can be shared to make a way? thanks a lot.

Wonderful work and the explanation is more believed. I also gained a lot althought I was not so familiar with node material editors. Now I got the intended box but seems I failed to apply a jpg/png material on the box.

I Working on how to do that on NodeMaterial later.
