int textureQueryLevels( gsampler3D sampler);
int textureQueryLevels( gsamplerCube sampler);
int textureQueryLevels( gsampler1DArray sampler);
int textureQueryLevels( gsampler2DDArray sampler);
int textureQueryLevels( gsamplerCubeArray sampler);
int textureQueryLevels( gsampler1DShadow sampler);
int textureQueryLevels( gsampler2DShadow sampler);
int textureQueryLevels( gsamplerCubeShadow sampler);
int textureQueryLevels( gsampler1DArrayShadow sampler);
int textureQueryLevels( gsampler2DArrayShadow sampler);
int textureQueryLevels( gsamplerCubeArrayShadow sampler);

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.
