NAME
    tex3Dfetch - performs an unfiltered texture lookup in a given sampler.

SYNOPSIS
      float4 tex3Dfetch(sampler3D samp, int4 s)
      float4 tex3Dfetch(sampler3D samp, int4 s, int texelOff)

      int4 tex3Dfetch(isampler3D samp, int4 s)
      int4 tex3Dfetch(isampler3D samp, int4 s, int texelOff)

      unsigned int4 tex3Dfetch(usampler3D samp, int4 s)
      unsigned int4 tex3Dfetch(usampler3D samp, int4 s, int texelOff)

PARAMETERS
    samp    Sampler to lookup.

    s       Coordinates to perform the lookup. The level of detail is stored
            in the last component of the coordinate vector.

    texelOff
            Offset to be added to obtain the final texel.

DESCRIPTION
    Performs an unfiltered texture lookup in sampler *samp* using
    coordinates *s*. The level of detail is provided by the last component
    of the coordinate vector. May use texel offset *texelOff* to compute
    final texel.

PROFILE SUPPORT
    tex3Dfetch is only supported in gp4 and newer profiles.
