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.
