<para>

<function>glBindFramebuffer</function> binds the framebuffer object with name <parameter>framebuffer</parameter> to the framebuffer target specified
|
|
by <parameter>target</parameter>. <parameter>target</parameter> must be either <constant>GL_DRAW_FRAMEBUFFER</constant>,
|
|
<constant>GL_READ_FRAMEBUFFER</constant> or <constant>GL_FRAMEBUFFER</constant>. If a framebuffer object is bound to
|
|
<constant>GL_DRAW_FRAMEBUFFER</constant> or <constant>GL_READ_FRAMEBUFFER</constant>, it becomes the target for
|
|
rendering or readback operations, respectively, until it is deleted or another framebuffer is bound to the corresponding bind point.
|
|
Calling <function>glBindFramebuffer</function> with <parameter>target</parameter> set to <constant>GL_FRAMEBUFFER</constant> binds
|
|
<parameter>framebuffer</parameter> to both the read and draw framebuffer targets.

<para>
|
|
The storage, dimensions, allocation, and format of the images attached to the default framebuffer are managed entirely
|
|
by the window system. In order that access to the default framebuffer is not lost, it is treated as a framebuffer object with the name of zero.
|
|
The default framebuffer is therefore rendered to and read from while zero is bound to the corresponding targets.
