Parameters
| Variables | Description |
|---|---|
| target |
Specify the target of the bind operation.
target
must be
one of
GL_ATOMIC_COUNTER_BUFFER
,
GL_TRANSFORM_FEEDBACK_BUFFER
,
GL_UNIFORM_BUFFER
or
GL_SHADER_STORAGE_BUFFER
.
|
| first |
Specify the index of the first binding point within the array specified by
target
.
|
| count |
Specify the number of contiguous binding points to which to bind buffers.
|
| buffers |
A pointer to an array of names of buffer objects to bind to the targets on the specified binding point, or
NULL
.
|
Description
glBindBuffersBase
binds a set of
count
buffer objects whose names
are given in the array
buffers
to the
count
consecutive binding
points starting from index
first
of the array of targets specified
by
target
. If
buffers
is
NULL
then
glBindBuffersBase
unbinds any buffers that are currently bound to the referenced binding points.
Assuming no errors are generated, it is equivalent to the following
pseudo-code, which calls
glBindBufferBase
,
with the exception that the non-indexed
target
is not changed by
glBindBuffersBase
:
for (i = 0; i < count; i++) {
if (buffers != NULL) {
glBindBufferBase(target, first + i, buffers[i]);
} else {
glBindBufferBase(target, first + i, 0);
}
}
Each entry in
buffers
will be checked individually and if found to be invalid, the state
for that buffer binding index will not be changed and an error will be generated. However, the state for
other buffer binding indices referenced by the command will still be updated.
Notes
glBindBuffersBase
is available only if the GL version is 4.4 or higher.
Errors
GL_INVALID_ENUM
is generated if
target
is not
GL_ATOMIC_COUNTER_BUFFER
,
GL_TRANSFORM_FEEDBACK_BUFFER
,
GL_UNIFORM_BUFFER
or
GL_SHADER_STORAGE_BUFFER
.
GL_INVALID_OPERATION
is generated if
first
+
count
is greater
than the number of target-specific indexed binding points.
GL_INVALID_OPERATION
is generated if any value in
buffers
is not
zero or the name of an existing buffer object.
