textureLodOffset 3G
textureLodOffset perform a texture lookup with explicit level-of-detail and offset

## Declaration

gvec4 `textureLodOffset` gsampler1D sampler float P float lod int offset gvec4 `textureLodOffset` gsampler2D sampler vec2 P float lod ivec2 offset gvec4 `textureLodOffset` gsampler3D sampler vec3 P float lod ivec3 offset float `textureLodOffset` sampler1DShadow sampler vec3 P float lod int offset float `textureLodOffset` sampler2DShadow sampler vec4 P float lod ivec2 offset gvec4 `textureLodOffset` gsampler1DArray sampler vec2 P float lod int offset gvec4 `textureLodOffset` gsampler2DArray sampler vec3 P float lod ivec2 offset float `textureLodOffset` sampler1DArrayShadow sampler vec3 P float lod int offset

## Parameters

sampler

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

P

  Specifies the texture coordinates at which the texture will be sampled.

lod

  Specifies the explicit level-of-detail from which texels will be fetched.

offset

  Specifies the offset that will be applied to P before texels are fetched.

## Description

`textureLodOffset` performs a texture lookup at coordinate P from the texture bound to sampler with an explicit level-of-detail as specified in lod. Behavior is the same as in textureLod except that before sampling, offset is added to P.
