Namespace Shard.Gameplay.Universe.World.Chunks

BlockChunk: Block data within a 32x32x32 chunk. Stores block types, rotations and filler offsets.

ChunkStorage: Caches generated block data by chunk position within the World bounds.

ChunkStreamer: Selects the chunks to send a player, streaming per (x,z) column so the client has each column's SetColumn container before its SetChunk chunks (otherwise the client buffers the chunks waiting for the column). Walks a horizontal square of radius horizontalRadius chunks, nearest column first (Chebyshev rings), across chunk-Y in [minChunkY, maxChunkY]; a column fully outside the world bounds is skipped. Streaming policy (how much, how paced) is the caller's; this is the pure selection.

ColumnHeightmap: Builds a column's surface heightmap (Java: BlockChunk.updateHeight): the world-Y of the highest non-transparent block at each (x,z) cell, or the column floor when a cell is all air. Every one of our placeholder blocks is opaque, so "non-transparent" is just "non-air" for now (a real block palette with opacity data refines this later). The result is a ColumnBytePalette ready to Serialize() into SetColumn.Heightmap.

ColumnSerializer: Assembles a SetColumn for an (x,z) column — the container the client needs before it applies the column's SetChunk sections (Java: BlockChunk.getCachedColumnPacket). It carries the surface ColumnHeightmap values and the tintmap palette.

PalettedChunkData: IChunkData implementation that internally palettes values, storing their indices rather than the values themselves. Can be serialized for use in Hytale.Protocol.Packets.World.SetChunk and Hytale.Protocol.Packets.World.SetFluids packets.
