BDOF (File Format)

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

Offset	Type	Description
0x00	String	File magic. Always PDOF in ASCII.
0x04	UInt32	File size. Always 0x50.
0x08	UInt32	Unknown. Always 0.
0x0C	UInt32	Unknown. Always 0.
0x10	UInt16	Seems to be some filter bitmask. If bit 15 is set, posteffect.bti will be used as an indirect texture.
0x12	Byte	Inverse alpha.
0x13	Byte	Alpha.
0x14	Byte	DOF draw mode: 0 = Unknown. Probably none. 1 = Only use inverse calculation. 2 = Use both normal and inverse calculations (normal calculations needed will be reflected if using posteffect.bti).
0x15	Byte	DOF draw amount.
0x16	Byte	DOF curve type.
0x17	Byte	Unknown.
0x18	Float	DOF plane distance.
0x1C	Float	DOF plane range.
0x20	Float	Unknown.
0x24	Float	DOF expand. A higher value means blurrier.
0x28	Float[2]	Indirect texture ST scroll speed.
0x30	Float[2]	Indirect texture indirect ST scale.
0x38	Float[2]	Indirect texture ST scale.
0x40	Byte[16]	Padding.
