The file contains UV texture coordinates for the ground triangles of an island section.
Texture coordinates usually have a representation from 0.0f->1.0f.
Therefore, to convert UV coordinates to the range 0.0f-1.0f, it is necessary to divide the UV by 65535.0f.
(U16)U/65535.0f = 0.0f-1.0f and (U16)V/65535.0f = 0.0f-1.0f
Specification[edit]
Each entry in the file consists of 12 bytes containing 3 texture coordinates.
1 entry = 1 ground triangle
The number of entries varies between island sections, depending on how many ground triangles are textured.
UV entry[edit]
- Offset 1: UNSIGNED SHORT (u16): U (Vertex 1)
- Offset 2: UNSIGNED SHORT (u16): V (Vertex 1)
- Offset 3: UNSIGNED SHORT (u16): U (Vertex 2)
- Offset 4: UNSIGNED SHORT (u16): V (Vertex 2)
- Offset 5: UNSIGNED SHORT (u16): U (Vertex 3)
- Offset 6: UNSIGNED SHORT (u16): V (Vertex 3)
