glBindSampler — bind a named sampler to a texturing target
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.
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.
