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:
