i read somewhere that continuous lod is very bad for the vertex caches of modern gpus.

i guess that's one the reasons conitec will implement chunked lod for terrains instead of continuous lod. it's easier to implement and faster.

the current 3dgs model lod solution is ok. it doesn't really matter if there are separate files or all stages in one file.


...
a tool which automatically creates the lod stages would be very cool indeed. i have worked with tools which handle that perfectly. i think they basically work somehow like that:

they render all animation frames of models from several different angles and then a brute force algorithm merges combinations of different vertices.

then they do image comparisons to find out which reductions lead to the least differences.

this can take several minutes per model.

...
but there are a lot of much more important 3dgs features to be done first!
