BDOF (File Format)

BDOF (Binary Depth Of Field) is a post-effect file in Mario Kart Wii that controls effects like focus, sharpness and blur in tracks. It is always seen in the "./posteffect" folder inside an U8 file.

There is unused code that allows the usage of a secondary BDOF file, named posteffect.bdof_demo. This one has the same format as a normal BDOF file, and it seems to be used only in the course introduction if present.

File Format

The file byte order is always big endian.
