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
component of P in the shadow forms is used as
.
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.
