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.
