Parameters
-
sampler
-
Specifies the sampler to which the texture whose mipmap level count will be queried is bound.
Description
textureQueryLevels returns the number of accessible mipmap levels
in the texture associated with sampler.
If called on an incomplete texture, or if no texture is associated with sampler, zero is returned.
