Based on both distance AND the number of entities within a node, nodes will be split, ergo the tree will usually not be static. Let's say you have a huge world but coincidentally the player never leaves one particular child node of the root. The other children could be completely empty and loading (and entity insertion) might only occur when you get within x distance of a particular node. | |

I thought you had to get the max XYZ values from each cube to get it's "center" position and boundaries for easier collision checking. But if it's just about entities then it's not as small as I thought I had to go, and means I can divide the area of my world in sections. I'm still unsure about #2 though, using Skyrim or WoW as example, does that means the entire game is in memory during play, but only a portion of it is shown? | |
