TEXTUREQUERYLOD(3G)             [FIXME: manual]            TEXTUREQUERYLOD(3G)

NAME
       textureQueryLod - compute the level-of-detail that would be used to
       sample from a texture

DECLARATION
       vec2 textureQueryLod(gsampler1D sampler, float P);

       vec2 textureQueryLod(gsampler2D sampler, vec2 P);

       vec2 textureQueryLod(gsampler3D sampler, vec3 P);

       vec2 textureQueryLod(gsamplerCube sampler, vec3 P);

       vec2 textureQueryLod(gsampler1DArray sampler, float P);

       vec2 textureQueryLod(gsampler2DArray sampler, vec2 P);

       vec2 textureQueryLod(gsamplerCubeArray sampler, vec3 P);

       vec2 textureQueryLod(sampler1DShadow sampler, float P);

       vec2 textureQueryLod(sampler2DShadow sampler, vec2 P);

       vec2 textureQueryLod(samplerCubeShadow sampler, vec3 P);

       vec2 textureQueryLod(sampler1DArrayShadow sampler, float P);

       vec2 textureQueryLod(sampler2DArrayShadow sampler, vec2 P);

       vec2 textureQueryLod(samplerCubeArrayShadow sampler, vec3 P);

PARAMETERS
       sampler
           Specifies the sampler to which the texture whose level-of-detail
           will be queried is bound.

       P
           Specifies the texture coordinates at which the level-of-detail will
           be queried.

DESCRIPTION
       Available only in the fragment shader, textureQueryLod computes the
       level-of-detail that would be used to sample from a texture. The mipmap
       array(s) that would be accessed is returned in the x component of the
       return value. The computed level-of-detail relative to the base level
       is returned in the y component of the return value.

       If called on an incomplete texture, the result of the operation is
       undefined.
