glBindSampler: bind a named sampler to a texturing target

Function Definition

 void glBindSampler(GLuint unit​, GLuint sampler​);
Specifies the index of the texture unit to which the sampler is bound.
Specifies the name of a sampler.


glBindSampler binds sampler​ to the texture unit at index unit​. sampler​ must be zero or the name of a sampler object previously returned from a call to glGenSamplers. unit​ must be less than the value of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.

When a sampler object is bound to a texture unit, its state supersedes that of the texture object bound to that texture unit. If the sampler name zero is bound to a texture unit, the currently bound texture's sampler state becomes active. A single sampler object may be bound to multiple texture units simultaneously.


glBindSampler is available only if the GL version is 3.3 or higher.


GL_INVALID_VALUE is generated if unit​ is greater than or equal to the value of GL_MAX_COMBIED_TEXTURE_IMAGE_UNITS.

GL_INVALID_OPERATION is generated if sampler​ is not zero or a name previously returned from a call to glGenSamplers, or if such a name has been deleted by a call to glDeleteSamplers.
