Enum Texture.InternalFormat

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Texture.InternalFormat>
    Enclosing class:
    Texture
    public static enum Texture.InternalFormat
extends java.lang.Enum<Texture.InternalFormat>
    Internal texel formats

    These formats are used to specify a texture's internal storage format.

    Enumerants syntax format

    [components][size][type]
    components : List of stored components by this format
    size : Size in bit of each component
    type : Type this format is stored as
    Name Component
    R Linear Red
    RG Linear Red, Green
    RGB Linear Red, Green, Blue
    RGBA Linear Red, Green Blue, Alpha
    SRGB sRGB encoded Red, Green, Blue
    DEPTH Depth
    STENCIL Stencil

    Name Type
    (none) Unsigned Normalized Integer [0, 1]
    _SNORM Signed Normalized Integer [-1, 1]
    UI Unsigned Integer [0, 2size]
    I Signed Integer [-2size-1, 2size-1-1]
    F Floating-point

    Special color formats

    There are a few special color formats that don't follow the convention above:
    Name Format
    RGB565 5-bits for R and B, 6-bits for G.
    RGB5_A1 5-bits for R, G and B, 1-bit for A.
    RGB10_A2 10-bits for R, G and B, 2-bits for A.
    RGB9_E5 Unsigned floating point. 9-bits mantissa for RGB, 5-bits shared exponent
    R11F_G11F_B10F Unsigned floating point. 6-bits mantissa, for R and G, 5-bits for B. 5-bits exponent.
    SRGB8_A8 sRGB 8-bits with linear 8-bits alpha.
    DEPTH24_STENCIL8 24-bits unsigned normalized integer depth, 8-bits stencil.

    Compressed texture formats

    Many compressed texture formats are supported as well, which include (but are not limited to) the following list:
    Name Format
    EAC_R11 Compresses R11UI
    EAC_R11_SIGNED Compresses R11I
    EAC_RG11 Compresses RG11UI
    EAC_RG11_SIGNED Compresses RG11I
    ETC2_RGB8 Compresses RGB8
    ETC2_SRGB8 compresses SRGB8
    ETC2_EAC_RGBA8 Compresses RGBA8
    ETC2_EAC_SRGBA8 Compresses SRGB8_A8
    ETC2_RGB8_A1 Compresses RGB8 with 1-bit alpha
    ETC2_SRGB8_A1 Compresses sRGB8 with 1-bit alpha
