. X file format detailed analysis. x file format

The picture below is. X file opened by DirectX Mesh View. today, we look at the X file's detail information. I stronugly recommand readers search "X File Format Reference" topic in DirectX SDK documentation.

 

 

 

 

 

 

The variable-length header is compulsory and must be at the beginning of the data stream. The header contains the following data.

 

Type Required Size (in bytes) Value Description
Magic Number x 4 "xof"
Version Number x 2 "03" Major version 3
"03" Minor version 3
Format Type x 4 "txt" Text File
"Bin" Binary file
"Tzip" MSZip compressed text file
"Bzip" MSZip compressed binary file
Float Size x "0064" 64-bit floats
X "0032" 32-bit floats
