GLNEWLIST() MachTen Programmer’s Manual GLNEWLIST()

NAME
glNewList, glEndList - create or replace a display list

C SPECIFICATION
void glNewList( GLuint list,
GLenum mode )

PARAMETERS
list Specifies the display-list name.

mode Specifies the compilation mode, which can be
GL_COMPILE or GL_COMPILE_AND_EXECUTE.

C SPECIFICATION
void glEndList( void )

DESCRIPTION
Display lists are groups of GL commands that have been
stored for subsequent execution. Display lists are cre-
ated 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 com-
piled.

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, glIsEn-
abled, glIsList, glNormalPointer, glPopClientAttrib,
glPixelStore, glPushClientAttrib, glReadPixels, glRender-
Mode, 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.

NOTES
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 cre-
ated in GL_COMPILE mode, errors are not generated until
the list is executed.

ERRORS
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.)
