textureLod — perform a texture lookup with explicit level-of-detail
gvec4 textureLod( | gsampler2D sampler, |
| vec2 P, | |
float lod); |
gvec4 textureLod( | gsampler3D sampler, |
| vec3 P, | |
float lod); |
gvec4 textureLod( | gsamplerCube sampler, |
| vec3 P, | |
float lod); |

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
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 and sets the partial derivatives as follows:
