<function>glRenderbufferStorageMultisample</function> establishes the data storage, format, dimensions and number of
|
|
samples of a renderbuffer object's image.

</para>
|

<para>
|
|
The target of the operation, specified by <parameter>target</parameter> must be <constant>GL_RENDERBUFFER</constant>.
|
|
<parameter>internalformat</parameter> specifies the internal format to be used for the renderbuffer object's storage and
|
|
must be a color-renderable, depth-renderable, or stencil-renderable format.
|
|
<parameter>width</parameter> and <parameter>height</parameter> are the dimensions, in pixels, of the renderbuffer.
|
|
Both <parameter>width</parameter> and <parameter>height</parameter> must be less than or equal to the value of
|
|
<constant>GL_MAX_RENDERBUFFER_SIZE</constant>. <parameter>samples</parameter> specifies the number of samples to be used
|
|
for the renderbuffer object's image, and must be less than or equal to the value of <constant>GL_MAX_SAMPLES</constant>.
|
|
If <parameter>internalformat</parameter> is a signed or unsigned integer format then <parameter>samples</parameter> must be
|
|
less than or equal to the value of <constant>GL_MAX_INTEGER_SAMPLES</constant>.
|
|
</para>
|

<para>
|
|
Upon success, <function>glRenderbufferStorageMultisample</function> deletes any existing data store for the renderbuffer
|
|
image and the contents of the data store after calling <function>glRenderbufferStorageMultisample</function> are undefined.
