textureProjLod 3G
textureProjLod perform a texture lookup with projection and explicit level-of-detail

## Declaration

gvec4 `textureProjLod` gsampler1D sampler vec2 P float lod gvec4 `textureProjLod` gsampler1D sampler vec4 P float lod gvec4 `textureProjLod` gsampler2D sampler vec3 P float lod gvec4 `textureProjLod` gsampler2D sampler vec4 P float lod gvec4 `textureProjLod` gsampler3D sampler vec4 P float lod float `textureProjLod` sampler1DShadow sampler vec4 P float lod float `textureProjLod` sampler2DShadow sampler vec4 P float lod

## 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.

## Description

`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 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 textureLod, with lod used to specify the level-of-detail from which the texture will be sampled.
