Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
|
|||
|
|
|
|||
|
|
The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
|
|||
|
|
packed custom format called FTEX. This file format uses file extensions FTC
|
|||
|
|
and FTU.
|
|||
|
|
* FTC files are compressed textures (using standard texture compression).
|
|||
|
|
* FTU files are not compressed.
|
|||
|
|
Texture File Format
|
|||
|
|
The FTC and FTU texture files both use the same format. This
|
|||
|
|
has the following structure:
|
|||
|
|
{header}
|
|||
|
|
{format_directory}
|
|||
|
|
{data}
|
|||
|
|
Where:
|
|||
|
|
{header} = {
|
|||
|
|
u32:magic,
|
|||
|
|
u32:version,
|
|||
|
|
u32:width,
|
|||
|
|
u32:height,
|
|||
|
|
u32:mipmap_count,
|
|||
|
|
u32:format_count
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
* The "magic" number is "FTEX".
|
|||
|
|
* "width" and "height" are the dimensions of the texture.
|
|||
|
|
* "mipmap_count" is the number of mipmaps in the texture.
|
|||
|
|
* "format_count" is the number of texture formats (different versions of the
|
|||
|
|
same texture) in this file.
|
|||
|
|
|
|||
|
|
{format_directory} = format_count * { u32:format, u32:where }
|
|||
|
|
|
|||
|
|
The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
|
|||
|
|
uncompressed textures.
|
|||
|
|
The texture data for a format starts at the position "where" in the file.
|
|||
|
|
|
|||
|
|
Each set of texture data in the file has the following structure:
|
|||
|
|
{data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
|
|||
|
|
* "mipmap_size" is the number of bytes in that mip level. For compressed
|
|||
|
|
textures this is the size of the texture data compressed with DXT1. For 24 bit
|
|||
|
|
uncompressed textures, this is 3 * width * height. Following this are the image
|
|||
|
|
bytes for that mipmap level.
|
|||
|
|
|
|||
|
|
Note: All data is stored in little-Endian (Intel) byte order.
