STATIC SUB CallList ( Index AS Integer )
Gl.CallList 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, Gl.CallList is ignored.
Gl.CallList 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 Gl.CallList. Thus, changes made to GL state during the execution of a display list remain after execution of the display list is completed. Use Gl.PushAttrib, Gl.PopAttrib, Gl.PushMatrix, and Gl.PopMatrix to preserve GL state across Gl.CallList calls.
![]() | Display lists can be executed between a call to Gl.Begin and the corresponding call to Gl.End, as long as the display list includes only commands that are allowed in this interval. |
