GLNEWLIST(3G)       UNIX Programmer's Manual        GLNEWLIST(3G)

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 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 gen-
     erated 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

     GL state. (It is as if no attempt had been made to create
     the new display list.)
