TEXTUREPROJLOD(3G)              [FIXME: manual]             TEXTUREPROJLOD(3G)

NAME
       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 3rd component of P in the shadow forms is
       used as Dref. 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.
