Loading Content by distance

In this experiment I tried to midigate long loading times by loading the stuff that is close to the camera first. For Each Cell there is a Thread loading that cell. Each cell contains 40x40 artifacts which have to be loaded.
Of course in this demo everything is simplified to toy problems. So there is no real data to load. Instead the workers are busy brute forcing some constructed problem. Each little rect represent a search intervall for the worker. The workers dont response when they are done, but rather every 750ms. The order in which they search their intervalls is depends on the on the current camera setup.
