Regions with many nearby points keep subdividing. Regions with few or no points stay large. The tree adapts to the data: dense areas get fine-grained cells, sparse areas stay coarse. The split grid is predetermined (always at midpoints), but the tree only refines cells that need it. Sparse regions stay as single large nodes while dense regions subdivide deeply.
Aurora lights shimmering over Earth were filmed on camera by Russia's space agency Roscosmos cosmonaut Sergey Kud-Sverchkov from the International Space Station. The phenomenon is caused by solar storms emitting high-speed charged particles colliding with gases in Earth’s atmosphere. The most common colour seen during this display is green, although other colours such as pink and red are sometimes visible as well.
