First thing is world generation
Want to do based SoA game instead of cringe AoS
So 'opaque' is a thing as its a bool we can have u64s.
64x64x64? no 128x128x64? maybe, z axis can be u64 so query above is if adjacent bits
but how to make it so god damn everything doesn go through the slow path ping pong for everything and its one frame to the next? duplication of stored data, chunks are myabe a few less but does not being a power of 2 fuck it? but yea if its all neighbour based
yep chunks are powers of 2 but the mapping onto world coords is -1 from each side, so neighbours can be sampled fast but it needs to be reconciled if a write occurs
and theres the complete information for the uniquely referenced values but what about the double ones that are shared by 2 separate slow pass?
Other ones for water (infiltrating) etc moisture, etc
not only that but correctness at edge of world
i think chunks should just pull from their neighbours and be 6-conn
and unloaded chunks, each chunk has sequence number, so when you load it can update up to where it should be, thats ok, might be kinda cheaty like duping water or something.
definitely dont want hyper breakage, probably better if things steady state more, like jank minecraft water
meshing on GPU with a geometry shader is a good option (not every frame)
any benefit to chunks, subchunks? eg mesh at higher level different chunk resolution for different things could you do chunk edge bookkeeping? only really solves half the problem
using glMultiDrawElements and
ok somethings still just NQR. and i need to clamp that shit as well.
