    Description
    BilinearNearestMipMap
    Same as BilinearNoMipMaps except that instead of using samples from texture level 0, the closest mipmap level is chosen based on distance.
    BilinearNoMipMaps
    In this method the four nearest texels to the pixel center are sampled (at texture level 0), and their colors are combined by weighted averages.
    NearestLinearMipMap
    Similar to NearestNeighborNoMipMaps except that instead of using samples from texture level 0, a sample is chosen from each of the closest (by distance) two mipmap levels.
    NearestNearestMipMap
    Same as NearestNeighborNoMipMaps except that instead of using samples from texture level 0, the closest mipmap level is chosen based on distance.
    NearestNoMipMaps
    Nearest neighbor interpolation is the fastest and crudest filtering method - it simply uses the color of the texel closest to the pixel center for the pixel color.
    Trilinear
    Trilinear filtering is a remedy to a common artifact seen in mipmapped bilinearly filtered images: an abrupt and very noticeable change in quality at boundaries where the renderer switches from one mipmap level to the next.

    • NearestNoMipMaps

      public static final Texture.MinFilter NearestNoMipMaps
      Nearest neighbor interpolation is the fastest and crudest filtering method - it simply uses the color of the texel closest to the pixel center for the pixel color. While fast, this results in aliasing and shimmering during minification. (GL equivalent: GL_NEAREST)

    • BilinearNoMipMaps

      public static final Texture.MinFilter BilinearNoMipMaps
      In this method the four nearest texels to the pixel center are sampled (at texture level 0), and their colors are combined by weighted averages. Though smoother, without mipmaps it suffers the same aliasing and shimmering problems as nearest NearestNeighborNoMipMaps. (GL equivalent: GL_LINEAR)

    • NearestNearestMipMap

      public static final Texture.MinFilter NearestNearestMipMap
      Same as NearestNeighborNoMipMaps except that instead of using samples from texture level 0, the closest mipmap level is chosen based on distance. This reduces the aliasing and shimmering significantly, but does not help with blockiness. (GL equivalent: GL_NEAREST_MIPMAP_NEAREST)

    • BilinearNearestMipMap

      public static final Texture.MinFilter BilinearNearestMipMap
      Same as BilinearNoMipMaps except that instead of using samples from texture level 0, the closest mipmap level is chosen based on distance. By using mipmapping we avoid the aliasing and shimmering problems of BilinearNoMipMaps. (GL equivalent: GL_LINEAR_MIPMAP_NEAREST)

    • NearestLinearMipMap

      public static final Texture.MinFilter NearestLinearMipMap
      Similar to NearestNeighborNoMipMaps except that instead of using samples from texture level 0, a sample is chosen from each of the closest (by distance) two mipmap levels. A weighted average of these two samples is returned. (GL equivalent: GL_NEAREST_MIPMAP_LINEAR)

    • Trilinear

      public static final Texture.MinFilter Trilinear
      Trilinear filtering is a remedy to a common artifact seen in mipmapped bilinearly filtered images: an abrupt and very noticeable change in quality at boundaries where the renderer switches from one mipmap level to the next. Trilinear filtering solves this by doing a texture lookup and bilinear filtering on the two closest mipmap levels (one higher and one lower quality), and then linearly interpolating the results. This results in a smooth degradation of texture quality as distance from the viewer increases, rather than a series of sudden drops. Of course, closer than Level 0 there is only one mipmap level available, and the algorithm reverts to bilinear filtering (GL equivalent: GL_LINEAR_MIPMAP_LINEAR)

  • Method Details

    • values

      public static Texture.MinFilter[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static Texture.MinFilter valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
