The glNewList and glEndList functions create or replace a display list.
void glNewList(
GLuint list,
GLenum mode
);
void glEndList(
void
);
Display lists are groups of OpenGL commands that have been stored for subsequent execution. The display lists are created with glNewList. All subsequent commands are placed in the display list, in the order issued, until glEndList is called.
The glNewList function has two parameters. The first parameter, list, is a positive integer that becomes the unique name for the display list. Names can be created and reserved with glGenLists and tested for uniqueness with glIsList. The second parameter, mode, is a symbolic constant that can assume one of the two preceding values.
Certain commands are not compiled into the display list, but are executed immediately, regardless of the display list mode. These commands are glIsList, glGenLists, glDeleteLists, glFeedbackBuffer, glSelectBuffer, glRenderMode, glReadPixels, glPixelStore, glFlush, glFinish, glIsEnabled, and all of the glGet routines.
When the glNewList function is encountered, the display list definition is completed by associating the list with the unique name list (specified in the glNewList command). If a display list with name list already exists, it is replaced only when glEndList is called.
The glCallList and glCallLists functions can be entered into display lists. The commands in the display list or lists executed by glCallList or glCallLists are not included in the display list being created, even if the list creation mode is GL_COMPILE_AND_EXECUTE.
The following function retrieves information related to glNewList:
glGet with argument GL_MATRIX_MODE
