NAME¶
textureQueryLevels - compute the number of accessible mipmap levels of a textureDECLARATION¶
int
textureQueryLevels(gsampler1D sampler);
int
textureQueryLevels(gsampler2D sampler);
int
textureQueryLevels(gsampler3D sampler);
int
textureQueryLevels(gsamplerCube sampler);
int

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¶
samplerSpecifies 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.VERSION SUPPORT¶
