By MaKiPL. All thanks goes to Halfer, for rich research progress on world map file. This wiki page is also based on Blue's wmx2obj source code.
Contents
General
Wmx.obj is world map geometry model only. Contains 835 segments, does not contain textures nor additional info like general header or pointers. Collision is calculated directly from faces. Towns and places on map are part of world map and are created the same way as mountains, ground etc. File size is 0x9000*835. Every 0x9000 a next segments starts.
Segment = contains 16 blocks Block = contains geometry
One block is 512 bytes, one segment is 8192 sized (512*16) + header. There is 16 blocks in a segment.
Segment
Segment starts with header (consist offsets for every block). After header a block data appears (a 4 byte header?) and polygon data.
- NOTE: Polygon is two triangles form a plane.
| Offset | Length | Description |
|---|---|---|
| 0 | 68 bytes | Header data |
| 68 | varies | Block data |
| varies | varies | Padding (00) |
Header data
| Offset | Length | Description |
|---|---|---|
| 0 | 4 bytes | unknown |
| 4 | 64 (16 * uint32) | Offsets to blocks position. 4 bytes every offset! |
Block data
Block data starts with header:
| Offset | Length | Description |
|---|---|---|
| 0 | Byte | Polygon count |
| 1 | Byte | Vertices count |
| 2 | Byte | Shadow(?) |
| 3 | Byte | Unknown |
Just after header a polygon data appears:
| Offset | Length | Description |
|---|---|---|
| 0 | Byte | F1 (Triangle 1) |
| 1 | Byte | F2 (Triangle 1) |
| 2 | Byte | F3 (Triangle 1) |
| 3 | Byte | F1 (Triangle 2) |
| 4 | Byte | F2 (Triangle 2) |
| 5 | Byte | F3 (Triangle 2) |
| 6 | Byte | U1 |
| 7 | Byte | V1 |
| 8 | Byte | U2 |
| 9 | Byte | V2 |
| 10 | Byte | U3 |
| 11 | Byte | V3 |
| 12 | 4 BIT/4 BIT | Texture Page/CLUT id |
| 13 | Byte | Ground type |
| 14 | Byte | Unknown |
| 15 | Byte | Unknown |
vertices:
| Offset | Length | Description |
|---|---|---|
| 0 | short | X vertex |
| 2 | short | Z vertex |
| 4 | short | Y vertex |
| 6 | 2 bytes | unknown |
Shadow(?) data: 8 bytes long. Currently not really known.
