Classes
struct	ADT
	A terrain tile for one client version. More...
struct	ADTFlying
	The flying bounds (MFBO), BC+. More...
struct	ADTSplit
	Cataclysm+ split-file tile chunks (the tile now spans root/_tex0/_obj0/ _obj1/_lod files). More...
struct	ADTTexFdids
	The 8.1+ FileDataID texture tables (_tex0), which replace MTEX names on height-texturing maps. More...
struct	ADTWotlk
	WotLK+ tile chunks: the water (MH2O) and the texture flags (MTXF). More...
struct	AlphaCodec
	MCAL codec: decode/encode the per-layer 64x64 alpha maps through AlphaMapCodec, indexing the sibling layers' flags + offsetInMcal. More...
class	AlphaMapCodec
	The MCAL alpha-map codec. More...
struct	InFileSpec
	Stored form of an inFile annotation: a binary chunk's physical-file group. More...
struct	LayerCodec
	MCLY codec: the texture layers, plus sizing alphaMaps to the layer count (MCAL may be absent on Cata+ when empty, so alphaMaps must be sized here to keep it aligned with layers). More...
struct	MapChunk
	A terrain chunk (MCNK) for one client version. More...
struct	MapChunkCata
	Vertex lighting (MCLV) and terrain materials (MCMT), Cata+. More...
struct	MapChunkColor
	Vertex colors (MCCV), WotLK+. More...
struct	MapChunkLegacyLiquid
	Legacy liquid (MCLQ). More...
struct	MapChunkReadCtx
	Context a sub-chunk codec needs to read one MCNK sub-chunk: the (already parsed) header, the sibling texture layers (MCAL indexes them), the tile alpha bit depth and whether to repair the 63x63 "unfixed" edge form. More...
struct	MapChunkWriteCtx
	Context a sub-chunk codec needs to write one MCNK sub-chunk. More...
struct	NormalCodec
	MCNR codec: 145 XZY normal triples followed by 13 undeclared padding bytes (a near-constant client pattern preserved for the semantic round-trip). More...
struct	SerializerSpec
	Stored form of a serializedBy annotation: the reflection of a codec type handling a sub-chunk that a plain readValue/writeValue cannot (external length, a transform, or a companion member). More...
struct	ShadowCodec
	MCSH codec: the 64x64 shadow map through ShadowMapCodec. More...
class	ShadowMapCodec
	The MCSH shadow-map codec: a 512-byte 1-bit bitmap on disk, a 4096-texel 0/1 surface in memory. More...
struct	SoundEmitterCodec
	MCSE codec: typed emitter records — the era picks the entry (pre-WotLK 52-byte CWSoundEmitterVanilla, 28-byte CWSoundEmitter after; the member's value_type carries the choice). More...
class	TerrainMapCodec
	Shared geometry for the 64x64 terrain map codecs: the last-row/column repair the client applies to "unfixed" maps on load. More...

Functions
LiquidVertexFormat	resolveVertexFormat (std::uint16_t stored, std::size_t totalBytes, std::size_t n)
	Resolve a liquid instance's vertex layout from its stored field and the span of its vertex-data block: the offset-multiplier method (wowdev), robust across every client.
void	appendBytes (FileBuffer &out, const void *p, std::size_t n)
	Append n raw bytes at p to out (a byte-copy primitive).

Variables
constexpr std::size_t	AlphaDim = 64
	The edge length of the decoded square edit surface (64).
constexpr std::size_t	AlphaTexels = AlphaDim * AlphaDim
	The texel count of a decoded map (64 * 64 = 4096).
constexpr std::size_t	Alpha4BitBytes = AlphaTexels / 2
	The on-disk size of a 4-bit alpha map (4096 / 2 = 2048 bytes).
constexpr std::size_t	ShadowBytes = AlphaTexels / 8
	The on-disk size of a 1-bit shadow bitmap (4096 / 8 = 512 bytes).
constexpr std::size_t	McvtCount = 145
	The 9x9 + 8x8 = 145 vertices of the MCVT height / MCNR normal grid.

◆ resolveVertexFormat()

LiquidVertexFormat wowlib::formats::adt::detail::resolveVertexFormat	(	std::uint16_t	stored,
