Depends on the implementation.<p>You don&#x27;t have to describe infinite (or very many) ever smaller layers at all times -- as with the fractal example, you can just render them when someone looks at them (which is almost always never below some point) and only at those areas and levels in which they look (make measurements) at a particular moment.<p>Besides, we assume a simulation that&#x27;s uniformly behaving at all points. They designer of the simulation could very well hard-code the result of that experiment to be what it is.
