DESCRIPTION


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
glAreTexturesResident,
glColorPointer,
glDeleteLists,
glDeleteTextures,
glDisableClientState,
glEdgeFlagPointer,
glEnableClientState,
glFeedbackBuffer,
glFinish,
glFlush,
glGenLists,
glGenTextures,
glIndexPointer,
glInterleavedArrays,
glIsEnabled,
glIsList,
glIsTexture,
glNormalPointer,
glPopClientAttrib,
glPixelStore,
glPushClientAttrib,
glReadPixels,
glRenderMode,
glSelectBuffer,
glTexCoordPointer,
glVertexPointer,
and all of the glGet commands.

Similarly, 
glTexImage1D, glTexImage2D, and glTexImage3D
are executed immediately and not compiled into the display list when their
first argument is GL_PROXY_TEXTURE_1D, GL_PROXY_TEXTURE_1D, or
GL_PROXY_TEXTURE_3D, respectively.

When the GL_ARB_imaging extension is supported,
glHistogram executes immediately when its argument is
GL_PROXY_HISTOGRAM.  Similarly, glColorTable executes
immediately when its first argument is glPROXY_COLOR_TABLE,
glPROXY_POST_CONVOLUTION_COLOR_TABLE, or
glPROXY_POST_COLOR_MATRIX_COLOR_TABLE.

When the GL_ARB_multitexture extension is supported,
glClientActiveTextureARB is not compiled into display lists, but
executed immediately.

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 created 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.)
