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.
bias
Specifies an optional bias to be applied during level-of-detail computation.
texture samples texels from the texture bound to sampler at texture
coordinate P. An optional bias, specified in bias is included in
the level-of-detail computation that is used to choose mipmap(s) from which to sample.
For shadow forms, the last component of P is used as
P.
For non-shadow variants, the array layer comes from the last component of P.
