Stop chunking together voxels.
They can still be requested/delivered in blocks if there are performance motivations, but less of the code should care about the concept of terrain blocks/chunks, and care only about voxels. Mesh extraction works on arbitrary edges now, so it can be done at the voxel level.
Load/unload state is tracked per-edge instead of per-chunk. Loading is noticeably slower. The client SurroundingsLoader is still working on chunks, which might be part of the reason.
Two blocking issues:
- Load speed is still noticeably slower
- Edges aren't properly unloaded!
I think the problem has to do with when edges from a higher LOD don't have corresponding edges in a lower LOD (ones going through the middle of a lower-LOD voxel). The code that used to downgrade chunk LODs should be responsible for this now.
I think edge reloading is fixed (there was a bug in rust-isosurface-extraction), but chunk/edge unloading logic is still shaky. Also framerate and load speed are bad.
