void glNewList(

void glEndList(void)
- list
- Specifies the display-list name.
- mode
- Specifies the compilation mode, which can be GL_COMPILE or
GL_COMPILE_AND_EXECUTE.
Display lists are groups of GL commands that have been stored for subsequent
execution. Display lists are created with glNewList. All subsequent
commands are placed in the display list, in the order issued, until
glEndList is called.
glNewList has two arguments. The first argument,
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 argument,
mode, is a symbolic constant that can assume one of two
values:
- GL_COMPILE
- Commands are merely compiled.
- GL_COMPILE_AND_EXECUTE
- Commands are executed as they are compiled into the display list.
Certain commands are not compiled into the display list but are executed
immediately, regardless of the display-list mode. These commands are glColorPointer, glDeleteLists, glDisableClientState, glEdgeFlagPointer, glEnableClientState, glFeedbackBuffer, glFinish, glFlush, glGenLists, glIndexPointer, glInterleavedArrays, glIsEnabled, glIsList, glNormalPointer, glPopClientAttrib, glPixelStore, glPushClientAttrib, glReadPixels, glRenderMode, glSelectBuffer, glTexCoordPointer, glVertexPointer, and all of the glGet commands.
Similarly, glTexImage2D and glTexImage1D are executed immediately
and not compiled into the display list when their first argument is
GL_PROXY_TEXTURE_2D or GL_PROXY_TEXTURE_1D,
respectively.
When glEndList 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.
glCallList and glCallLists can be entered into display
lists. 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.
A display list is just a group of commands and arguments, so errors generated
by commands in a display list must be generated when the list is executed. If
the list is created in GL_COMPILE mode, errors are not
generated until the list is executed.
- GL_INVALID_VALUE is generated if list is
0.
- GL_INVALID_ENUM is generated if mode is
not an accepted value.
- GL_INVALID_OPERATION is generated if glEndList is called without a preceding
glNewList, or if glNewList is called while a display
list is being defined.
- GL_INVALID_OPERATION is generated if glNewList or glEndList is executed between the
execution of glBegin and the
corresponding execution of glEnd.
- GL_OUT_OF_MEMORY is generated if there is insufficient
memory to compile the display list. If the GL version is 1.1 or greater,
no change is made to the previous contents of the display list, if any,
and no other change is made to the GL state. (It is as if no attempt had
been made to create the new display list.)
