  • Field Details

    • TEX2D

      protected static final int TEX2D
      Texture with normalized UV.
      See Also:

    • TEXRECT

      protected static final int TEXRECT
      Texture with un-normalized UV.
      See Also:

    • POINT

      protected static final int POINT
      Point sampling: both magnification and minification filtering are set to nearest
      See Also:

    • LINEAR

      protected static final int LINEAR
      Linear sampling: magnification filtering is nearest, minification set to linear
      See Also:

    • BILINEAR

      protected static final int BILINEAR
      Bilinear sampling: both magnification filtering is set to linear and minification either to linear-mipmap-nearest (linear interpolation is used within a mipmap, but not between different mipmaps).
      See Also:

    • TRILINEAR

      protected static final int TRILINEAR
      Trilinear sampling: magnification filtering set to linear, minification to linear-mipmap-linear, which offers the best mipmap quality since linear interpolation to compute the value in each of two maps and then interpolates linearly between these two values.
