41 | <function>glCallList</function> causes the named display list to be executed. | |
42 | The commands saved in the display list are executed in order, | |
43 | just as if they were called without using a display list. | |
44 | If <parameter>list</parameter> has not been defined as a display list, | |
45 | <function>glCallList</function> is ignored. | |
46 | </para> | |
47 | <para> | |
48 | <function>glCallList</function> can appear inside a display list. | |
49 | To avoid the possibility of infinite recursion resulting from display lists | |
50 | calling one another, | |
51 | a limit is placed on the nesting level of display | |
52 | lists during display-list execution. | |
53 | This limit is at least 64, and it depends on the implementation. | |
54 | </para> | |
55 | <para> | |
56 | GL state is not saved and restored across a call to <function>glCallList</function>. | |
57 | Thus, | |
58 | changes made to GL state during the execution of a display list | |
59 | remain after execution of the display list is completed. | |
60 | Use <citerefentry><refentrytitle>glPushAttrib</refentrytitle></citerefentry>, | |
61 | <citerefentry><refentrytitle>glPopAttrib</refentrytitle></citerefentry>, | |
62 | <citerefentry><refentrytitle>glPushMatrix</refentrytitle></citerefentry>, | |
63 | and <citerefentry><refentrytitle>glPopMatrix</refentrytitle></citerefentry> to preserve GL state across <function>glCallList</function> calls. | |

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