I was looking for a post mentioning the build engine. Obviously it came a little later and has higher hardware requirements, but I wonder if this is really related to the sector approach, or whether it's mostly other parts of the engine. It seems much more elegant as it directly uses the data structures that represent the level layout, thus not requiring a preprocessing step, and intuitively I don't see how it's more expensive than walking a tree for every frame. Did anyone do a more thorough investigation into this? I know Doom's engine has been analyzed to death regarding every little detail, but build/duke3d didn't get nearly as much attention.
