    .SH "PARAMETERS"

        .PP sampler

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

            .RE
            .PP P

                        Specifies the texture coordinates at which texture will be sampled.

                .RE
                .PP lod

                            Specifies the explicit level-of-detail

                .SH "DESCRIPTION"
                    .PP 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 λbase and sets the partial derivatives as follows:
                    .PP δ u δ x = 0 , δ v δ x = 0 , δ w δ x = 0 δ u δ y = 0 , δ v δ y = 0 , δ w δ y = 0
