## Declaration

gvec4 `textureProjLodOffset` gsampler1D sampler vec2 P float lod int offset gvec4 `textureProjLodOffset` gsampler1D sampler vec4 P float lod int offset gvec4 `textureProjLodOffset` gsampler2D sampler vec3 P float lod ivec2 offset gvec4 `textureProjLodOffset` gsampler2D sampler vec4 P float lod ivec2 offset gvec4 `textureProjLodOffset` gsampler3D sampler vec4 P float lod ivec3 offset float `textureProjLodOffset` sampler1DShadow sampler vec4 P float lod int offset float `textureProjLodOffset` sampler2DShadow sampler vec4 P float lod ivec2 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 texture will be sampled.

lod

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

offset

  Specifies the offset, in texels, to be applied to P before fetching texels.

## Description

`textureProjLodOffset` performs a texture lookup with projection from an explicitly specified level-of-detail with an offset applied to the texture coordinates before sampling. The texture coordinates consumed from P, not including the last component of P, are divided by the last component of P. The resulting 3 rd component of P in the shadow forms is used as D ref. After these values are computed, the texture lookup proceeds as in textureLodOffset, with lod used to specify the level-of-detail from which the texture will be sampled and offset used to specifiy the offset, in texels, to be applied to the texture coordinates before sampling.
