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.
Name
textureLodOffset - perform a texture lookup with explicit level-of-detail and offset
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.
