glCallList — execute a display list
glCallList 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
list has not been defined as a display list,
glCallList is ignored.
glCallList 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.
GL state is not saved and restored across a call to
glCallList. Thus, changes made to GL state during the execution of a display list remain after execution of the display list is completed. Use glPushAttrib, glPopAttrib, glPushMatrix, and glPopMatrix to preserve GL state across
