This sample demonstrates the concept of "display lists", which was introduced in OpenGL 1.1.\par
|
||
\par
|
||
Display lists provide the fastest way to display static geometry (even faster than vertex buffer objects in some cases). On the other hand, geometry built into a display list cannot be modified after the fact.\par
|
||
\par
|
||
Please note that display lists are not supported in OpenGL 3.1 or higher.\par

1. The OnLoad event handler builds the display lists. OpenGL commands placed within a GL.NewList()-GL.EndList() region are recorded into the display list. (Note that some OpenGL commands cannot be recorded - consult the OpenGL reference for more information).\par
|
||
\par
|
||
2. The OnRenderFrame event handler uses GL.CallLists() to render the display lists. This command takes an array of valid display list ids and "replays" the commands recorded in each list.\par
|
||
\par
|
||
3. The OnUnload event handler uses GL.DeleteLists() to clean up the display lists.\par
