<function>glCallList</function> causes the named display list to be executed.
|
|
The commands saved in the display list are executed in order,
|
|
just as if they were called without using a display list.
|
|
If <parameter>list</parameter> has not been defined as a display list,
|
|
<function>glCallList</function> is ignored.

</para>
|
|
<para>
|
|
<function>glCallList</function> can appear inside a display list.
|
|
To avoid the possibility of infinite recursion resulting from display lists
|
|
calling one another,
|
|
a limit is placed on the nesting level of display
|
|
lists during display-list execution.
|
|
This limit is at least 64, and it depends on the implementation.
|
|
</para>
|
|
<para>
|
|
GL state is not saved and restored across a call to <function>glCallList</function>.
|
|
Thus,
|
|
changes made to GL state during the execution of a display list
|
|
remain after execution of the display list is completed.
|
|
Use <citerefentry><refentrytitle>glPushAttrib</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glPopAttrib</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glPushMatrix</refentrytitle></citerefentry>,
|
|
and <citerefentry><refentrytitle>glPopMatrix</refentrytitle></citerefentry> to preserve GL state across <function>glCallList</function> calls.

Display lists can be executed between a call to <citerefentry><refentrytitle>glBegin</refentrytitle></citerefentry>
|
|
and the corresponding call to <citerefentry><refentrytitle>glEnd</refentrytitle></citerefentry>,
|
|
as long as the display list includes only commands that are allowed
|
|
in this interval.
