PATH (File Format)

The PATH format is used to store an area's Navigation Mesh in the Metroid Prime series. Like navigation meshes in many other game engines (Unreal Engine 2, Source, etc...), the PATH format represents an n-gon mesh partitioned into a BSP tree for rapid queries.

Please Note: PATH meshes use the local coordinate system of the MREA. One must multiply PATH coordinates as a column-vector with the matrix at offset 0x8 in the MREA to get world coordinates.
