This is another temporary version on the way to Cataclysm after ADT/v22. It now has more chunks. (well, there are now more chunks in the leaked files.)
Do not bother implementing until final version is there. This is not used in current clients.
There might be some changes in the chunks below. I have not yet checked them but only added new ones!
This document may not list all chunks.
AHDR: HeaDeR
- size: 0x40
DWORD // 22 DWORD vertices_x // 129 DWORD vertices_y // 129 DWORD chunks_x // 16 DWORD chunks_y // 16 DWORD[10]
AVTX: VerTeX
- size: may be variable. Its based on the header. header.vertices_x*header.vertices_y + (header.vertices_x-1)*(header.vertices_y-1) * 4 bytes (float).
A large collection of floats. Again with inner[(header.vertices_x-1)*(header.vertices_y-1)] and outer[header.vertices_x*header.vertices_y] vertices.
Important: These are NOT mixed as in the ADT/v18s, but have the 129*129 field first, then the 128*128 one.
float outer[129][129]; float inner[128][128];
for example. Same should apply for the normals.
ANRM: NoRMals
- size: may be variable. Its based on the header. header.vertices_x*header.vertices_y + (header.vertices_x-1)*(header.vertices_y-1) * 3 bytes.
Like ADT/v18, these are triples of chars being a vector. 127 is 1.0, -127 is -1.0.
ATEX: TEXtures
- size: variable
Used for texture filenames. This is an array of chunks. There are as many chunks as there are textures used in this ADT tile.
ADOO: DOOdad
- size: variable
Used for M2/WotLK and WMO filenames. Both are in here. Again, an array of chunks with a chunk for every filename.
ACNK: ChuNK
- size: variable
This one is a bit like the MCNK one. There is an header for it, if the size is bigger than 0x40. If it has an header, its like this:
int indexX int indexY DWORD int areaId WORD DWORD[4] lowdetailtextureingmap WORD DWORD[7]
ALYR: LaYeR
- size: 0x20 or more.
This will include the alpha map if flags&0x100.
int textureID // as in ATEX int flags DWORD[6]
AMAP: alpha MAP
- optional. size: variable (?)
most likely like the old one.
ASHD: SHaDow map
- optional. size: 0x200 (?)
most likely like the old one.
ACDO: Chunk - Definitions of Objects
- optional. size: 0x38
Doodads and WMOs are now both defined here.
int modelid // as in ADOO float position[3] float rotation[3] float scale[3] float uint uniqueId DWORD[] // name / doodadsets?
AFBO: Flight BOx information
- size: 0x48
This again is just a list of two planes in shorts.
short[3][3] maximum; short[3][3] minimum;
ACVT: (Chunk?) VerTex shading
- size: may be variable. Its based on the header. header.vertices_x*header.vertices_y + (header.vertices_x-1)*(header.vertices_y-1) * 4 bytes. Like AVTX.
This now is over the whole ADT as the heightmap instead being a subchunk of the ACNK chunk. These are color values defined with 4 bytes: RGBA.
