glCallLists

glCallLists: man2/glCallLists.xml

glCallLists causes each display list in the list of names passed as lists to be executed. As a result, the commands saved in each display list are executed in order, just as if they were called without using a display list. Names of display lists that have not been defined are ignored. glCallLists provides an efficient means for executing more than one display list. type allows lists with various name formats to be accepted. The formats are as follows: The list of display-list names is not null-terminated. Rather, n specifies how many names are to be taken from lists. An additional level of indirection is made available with the glListBase command, which specifies an unsigned offset that is added to each display-list name specified in lists before that display list is executed. glCallLists 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 must be at least 64, and it depends on the implementation. GL state is not saved and restored across a call to glCallLists. Thus, changes made to GL state during the execution of the display lists remain after execution is completed. Use glPushAttrib, glPopAttrib, glPushMatrix, and glPopMatrix to preserve GL state across glCallLists calls.

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