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.
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.
