Idk how to tell you my issue...

Unity Engine

… because I have no idea how to describe it in the title!

I am looking for a way to finite my terrain visually. So I am looking from the birds view down to the map and it should be limited inside a cube. So, everything of the map, going outside the cube is not visible. Like the boolean function in some 3d programs:

The edged should be plane like in the picture. I have found some useful c#-stuff on lynda.com (‘Advanced Unity 3D Game Programming’ - Procedural Voxel Terrain) but it is not the same I am looking for.

The most important for me is to know what am I looking for. So, are there any known words for that? I even have no idea what to type in Google?!

Thanks in avance…

Thanks. But what about the Stencil Buffer? Is it a way to use for terrains? I would like to do exactly what you can see in this video. Thought there is some kind of a standard use for that kind of scrolling:
