Useful information about DDS
| Extension: | DDS |
|---|---|
| Name: | DirectDraw Surface |
| Mime Type: | image/vnd-ms |
| Converter: | DDS Converter |
| Description: | The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the previously proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. This makes the format useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed.[2] The file extension for this data format is dds. - Source |
Useful information about DXT5
| Extension: | DXT5 |
|---|---|
| Name: | S3 Texture Compression - Dxt5 |
| Mime Type: | image/dxt |
| Converter: | DXT5 Converter |
| Description: | The DXT5 format is an alternate RGBA format. As in the DXT3 case, each 4x4 block takes up 128 bits. So it provides the same 4:1 compression as in the DXT3 case. Just as for the DXT3 format, there are two 64-bit chunks of data per block: an RGB chunk compressed as for DXT1 (with the same caveat as for DXT3), and an alpha chunk. Again the second chunk is the color chunk; the first is the alpha. Where DXT3 and DXT5 differ is how the alpha chunk is compressed. DXT5 compresses the alpha using a compression scheme similar to DXT1. The alpha data is stored as 2 8-bit alpha values, alpha0 and alpha1, followed by a 48-bit unsigned integer that describes how to combine these two reference alpha values to achieve the final alpha value. The 48-bit integer is also stored in little-endian order. The 48-bit unsigned integer contains 3-bit codes that describe how to compute the final alpha value. These codes are stored in the identical order as the codes in DXT1; they simply are 3 bits in size rather than 2. - Source |
