fglNewList(3G) OpenGL Reference fglNewList(3G)NAME
fglNewList, fglEndList - create or replace a display list
FORTRAN SPECIFICATION
SUBROUTINE fglNewList( INTEGER*4 list,
INTEGER*4 mode )
PARAMETERS
list Specifies the display-list name.
mode Specifies the compilation mode, which can be GL_COMPILE or
GL_COMPILE_AND_EXECUTE.
FORTRAN SPECIFICATION
SUBROUTINE fglEndList( )
DESCRIPTION
Display lists are groups of GL commands that have been stored for
subsequent execution. Display lists are created with fglNewList. All
subsequent commands are placed in the display list, in the order issued,
until fglEndList is called.
fglNewList 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 fglGenLists and tested for uniqueness with
fglIsList. 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
fglAreTexturesResident, fglColorPointer, fglDeleteLists,
fglDeleteTextures, fglDisableClientState, fglEdgeFlagPointer,
fglEnableClientState, fglFeedbackBuffer, fglFinish, fglFlush,
fglGenLists, fglGenTextures, fglIndexPointer, fglInterleavedArrays,
fglIsEnabled, fglIsList, fglIsTexture, fglNormalPointer,
fglPopClientAttrib, fglPixelStore, fglPushClientAttrib, fglReadPixels,
fglRenderMode, fglSelectBuffer, fglTexCoordPointer, fglVertexPointer, and
all of the fglGet commands.
Similarly, fglTexImage1D, fglTexImage2D, and fglTexImage3D 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, fglHistogram executes
immediately when its argument is GL_PROXY_HISTOGRAM. Similarly,
fglColorTable executes immediately when its first argument is
fglPROXY_COLOR_TABLE, fglPROXY_POST_CONVOLUTION_COLOR_TABLE, or
fglPROXY_POST_COLOR_MATRIX_COLOR_TABLE.
When fglEndList is encountered, the display-list definition is completed
by associating the list with the unique name list (specified in the
fglNewList command). If a display list with name list already exists, it
is replaced only when fglEndList is called.
NOTES
fglCallList and fglCallLists can be entered into display lists. Commands
in the display list or lists executed by fglCallList or fglCallLists 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 fglEndList is called without a
preceding fglNewList, or if fglNewList is called while a display list is
being defined.
GL_INVALID_OPERATION is generated if fglNewList or fglEndList is executed
between the execution of fglBegin and the corresponding execution of
fglEnd.
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.)
