PARAMETERS

sampler

Specifies the sampler to which the texture whose dimensions to retrieve is bound.

lod

Specifies the level of the texture for which to retrieve the dimensions.

DESCRIPTION

textureSize returns the dimensions of level lod (if present) of the texture bound to sampler. The components in the return value are filled in, in order, with the width, height and depth of the texture. For the array forms, the last component of the return value is the number of layers in the texture array.
