Bind a named sampler to a texturing target.

C Specification[edit]

void glBindSampler( GLuint unit, GLuint sampler );


unit - Specifies the index of the texture unit to which the sampler is bound.
sampler - 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_COMBINED_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 .
