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

NAME
       textureLod - perform a texture lookup with explicit level-of-detail

DECLARATION
       gvec4 textureLod(gsampler1D sampler, float P, float lod);

       gvec4 textureLod(gsampler2D sampler, vec2 P, float lod);

       gvec4 textureLod(gsampler3D sampler, vec3 P, float lod);

       gvec4 textureLod(gsamplerCube sampler, vec3 P, float lod);

       float textureLod(sampler1DShadow sampler, vec3 P, float lod);

       float textureLod(sampler2DShadow sampler, vec4 P, float lod);

       gvec4 textureLod(gsampler1DArray sampler, vec2 P, float lod);

       gvec4 textureLod(gsampler2DArray sampler, vec3 P, float lod);

       float textureLod(sampler1DArrayShadow sampler, vec3 P, float lod);

       gvec4 textureLod(gsamplerCubeArray sampler, vec4 P, float lod);

PARAMETERS
       sampler
           Specifies the sampler to which the texture from which texels will
           be retrieved is bound.

       P
           Specifies the texture coordinates at which texture will be sampled.

       lod
           Specifies the explicit level-of-detail

DESCRIPTION
       textureLod performs a texture lookup at coordinate P from the texture
       bound to sampler with an explicit level-of-detail as specified in lod.
       lod specifies <lambda>base and sets the partial derivatives as follows:

       <delta> u <delta> x = 0 , <delta> v <delta> x = 0 , <delta> w <delta> x
       = 0 <delta> u <delta> y = 0 , <delta> v <delta> y = 0 , <delta> w
       <delta> y = 0
