## Parameters

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.

dPdx

  Specifies the partial derivative of P with respect to window x.

dPdy

  Specifies the partial derivative of P with respect to window y.

offset

  Specifies the offset to be applied to the texture coordinates before sampling.

## Description

`textureGradOffset` performs a texture lookup at coordinate P from the texture bound to sampler with explicit texture coordinate gradiends as specified in dPdx and dPdy. An explicit offset is also supplied in offset. `textureGradOffset` consumes dPdx and dPdy as textureGrad and offset as textureOffset.
