DIV (File Format)
From Wexos's Wiki
(Redirected from DIV)
DIV files (DIVision) are used in Mario Kart 7 tracks to subdivide the course model in clipping bounding boxes, to reduce lag.
File Format
The file byte order is always little endian.
Header
The file starts with a header that is 0x10 bytes long.
| Offset | Type | Description |
|---|---|---|
| 0x00 | Char[4] | File magic. Always BADC in ASCII. |
| 0x04 | UInt32 | File size in bytes. |
| 0x08 | UInt32 | PAHS offset. Always 0x10. |
| 0x0C | Int32 | Unknown. Always 1000. |
PAHS
The PAHS section (SHAPe) contains a group of streams, one per polygon in the course BCRES file. The streams follow the same order as the polygons.
| Offset | Type | Description |
|---|---|---|
| 0x00 | Char[4] | Section magic. Always PAHS in ASCII. |
| 0x04 | Int32 | Number of MRTS sections. |
MRTS
The MRTS section (STReaM) contains axis-aligned bounding boxes (AABBs) that correspond to the polygon from the course model.
| Offset | Type | Description |
|---|---|---|
| 0x00 | Char[4] | Section magic. Always MRTS in ASCII. |
| 0x04 | UInt16 | Number of bounding boxes (N). |
| 0x06 | UInt16 | Number of vertices in the polygon. |
| 0x08 + 0x10*N | Float[2] | Minimum position of the AABB. |
| 0x10 + 0x10*N | Float[2] | Maximum position of the AABB. |
