glBindSamplers — bind one or more named sampler objects to a sequence of consecutive sampler units
void glBindSamplers(
|
GLuint first, |
| GLsizei count, | |
const GLuint *samplers); |
first
Specifies the first sampler unit to which a sampler object is to be bound.
count
Specifies the number of samplers to bind.
samplers
Specifies the address of an array of names of existing sampler objects.
glBindSamplers binds samplers from an array of existing sampler objects to a specified
number of consecutive sampler units. count specifies the number of sampler
objects whose names are stored in the array samplers. That number
of sampler names is read from the array and bound to the count consecutive
sampler units starting from first.
If the name zero appears in the samplers array, any existing binding
to the sampler unit is reset. Any non-zero entry in samplers must be the
name of an existing sampler object. When a non-zero entry in samplers is
present, that sampler object is bound to the corresponding sampler unit.
If samplers is NULL then it is as
if an appropriately sized array containing only zeros had been specified.
glBindSamplers is equivalent to the following pseudo code:
for (i = 0; i < count; i++) {
if (samplers == NULL) {
glBindSampler(first + i, 0);
} else {
glBindSampler(first + i, samplers[i]);
}
}
Each entry in samplers will be checked individually and if found
to be invalid, the state for that sampler unit will not be changed and an error will be
generated. However, the state for other sampler units referenced by the command will still
be updated.
glBindSamplers is available only if the GL version is 4.4 or higher.
GL_INVALID_OPERATION is generated if first + count is greater
than the number of sampler units supported by the implementation.
GL_INVALID_OPERATION is generated if any value in samplers is
not zero or the name of an existing sampler object.
