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


Specifies the texture coordinates at which texture will be sampled.


Specifies the explicit level-of-detail from which to fetch texels.


textureProjLod performs a texture lookup with projection from an explicitly specified level-of-detail. The texture coordinates consumed from P, not including the last component of P, are divided by the last component of P. The resulting 3rd component of P in the shadow forms is used as Dref. After these values are computed, the texture lookup proceeds as in textureLod(), with lod used to specify the level-of-detail from which the texture will be sampled.
