</h2><p>
15 <code class=
"function">glFramebufferRenderbuffer
</code> attaches a renderbuffer as one of the logical buffers of the
16 currently bound framebuffer object.
<em class=
"parameter"><code>renderbuffer
</code></em> is the name of the renderbuffer object
17 to attach and must be either zero, or the name of an existing renderbuffer object of type
<em class=
"parameter"><code>renderbuffertarget
</code></em>.
18 If
<em class=
"parameter"><code>renderbuffer
</code></em> is not zero and if
<code class=
"function">glFramebufferRenderbuffer
</code> is
19 successful, then the renderbuffer name
<em class=
"parameter"><code>renderbuffer
</code></em> will be used as the logical buffer
20 identified by
<em class=
"parameter"><code>attachment
</code></em> of the framebuffer currently bound to
<em class=
"parameter"><code>target
</code></em>.
22 The value of
<code class=
"constant">GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE
</code> for the specified attachment point is
23 set to
<code class=
"constant">GL_RENDERBUFFER
</code> and the value of
<code class=
"constant">GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME
</code>
24 is set to
<em class=
"parameter"><code>renderbuffer
</code></em>. All other state values of the attachment point specified by
25 <em class=
"parameter"><code>attachment
</code></em> are set to their default values. No change is made to the state of the renderbuuffer
26 object and any previous attachment to the
<em class=
"parameter"><code>attachment
</code></em> logical buffer of the framebuffer
27 <em class=
"parameter"><code>target
</code></em> is broken.
29 Calling
<code class=
"function">glFramebufferRenderbuffer
</code> with the renderbuffer name zero will detach the image, if any,
30 identified by
<em class=
"parameter"><code>attachment
</code></em>, in the framebuffer currently bound to
<em class=
"parameter"><code>target
</code></em>.
31 All state values of the attachment point specified by attachment in the object bound to target are set to their default values.
33 Setting
<em class=
"parameter"><code>attachment
</code></em> to the value
<code class=
"constant">GL_DEPTH_STENCIL_ATTACHMENT
</code> is a special
34 case causing both the depth and stencil attachments of the framebuffer object to be set to
<em class=
"parameter"><code>renderbuffer
</code></em>,
35 which should have the base internal format
<code class=
"constant">GL_DEPTH_STENCIL
</code>.
