Parameters
-
sampler -
Specifies the sampler to which the texture from which texels will be retrieved is bound.
-
P -
Specifies the texture coordinates at which the texture will be sampled.
-
lod -
Specifies the explicit level-of-detail from which texels will be fetched.
-
offset -
Specifies the offset that will be applied to P before texels are fetched.
Description
textureLodOffset performs a texture lookup at coordinate P from the texture bound to sampler with an explicit level-of-detail as specified in lod. Behavior is the same as in textureLod except that before sampling, offset is added to P.
