DirectDraw Surface

The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the 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. The Microsoft Windows file extension for this data format is '.dds'.

History

This format was introduced with DirectX 7.0. In DirectX 8.0, support for volume textures was added. With Direct3D 10, the file format was extended to allow an array of textures to be included, as well as support for new Direct3D 10.x and 11 texture formats.

  • Digital Data Storage

    Digital Data Storage (DDS) is a format for storing computer data derived from Digital Audio Tape (DAT).

    DDS uses tape with a width of 3.81mm, with the exception of the latest formats, DAT 160 and DAT 320, which are 8mm wide. Initially, the tape was 60 meters (197 feet) or 90 meters (295 ft.) long. Advancements in materials technology have allowed the length to be increased significantly in successive versions. A DDS tape drive uses helical scanning for recording, the same process used by a video cassette recorder (VCR). If errors are present, the write heads rewrite the data.

    Backward compatibility between newer drives and older tapes is not assured; for examples, see HP's DDS Media Compatibility Matrix. (Notice in HP's article that newer tape standards do not simply consist of longer tapes; with DDS2, for example, the track was narrower than with DDS1.)

    The DDS format competes mainly against the LTO, AIT, VXA, and Travan formats.

    Generations

    Stores up to 1.3 GB uncompressed (2.6 GB compressed) on a 60 m cartridge, 2 GB uncompressed (4 GB compressed) on a 90 m cartridge.

    7 Days, 7 Weeks

    by: Deus

    Sister love, why don't you break it up?
    You got to let someone look into your heart
    Sister love, how do you keep it up?
    If you don't let no-one look into your heart
    As a kid, you couldn't live it up
    You were so serious but always so smart
    As a kid, you couldn't keep it up
    And we were never close, so much apart
    Here comes the sun smiling
    How long have you been blue?
    There'd ever be a time for us to recapture
    All the time we lose
    There was a time when you were being so proud
    Could have been anythin' that you aspired
    There was a time when you were never around
    When somethin' good happened, somethin' good happened right
    So sister love, I'll help you off the ground
    You got to let someone look into your heart
    You got to turn this situation around
    You got to turn this, turn it around
    Here comes the sun smiling
    How long have you been blue?
    There'd ever be a time for us to recapture
    All the time we lose
    'Cause it's plain to see
    A storm is not the weather
    And I'm telling you girl
    You'll look at them and smile
    I'm telling you girl
    You'll look at them and smile
    7 days you should be givin' yourself
    All your belongings, all that you treasure
    7 weeks you think of nobody else
    Is this what you want, is this what you are?
    How did it come this far?
    Here comes the sun smilin'
    The only thing that's true
    There'd ever be a time for us to recapture
    All the time we lose
    'Cause it's plain to see
    A storm is not the weather
    And I'm telling you girl
    You'll look at them and smile
    And I'm telling you girl
    You'll look at them and smile
    And I'm telling you girl
    You'll look at them and smile
    And I'm telling you girl
