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
Description
textureLod performs a texture lookup at coordinate P from the texture bound to sampler with an explicit level-of-detail as specified in lod. lod specifies and sets the partial derivatives as follows:
