Gl.EndList (gb.opengl)
Static Sub EndList ( )
Create or replace a display list.
Parameters
- list
-
Specifies the display-list name.
- mode
-
Specifies the compilation mode,
which can be
Gl.COMPILE or
Gl.COMPILE_AND_EXECUTE.
Description
Display lists are groups of GL commands that have been stored
for subsequent execution.
Display lists are created with
Gl.NewList.
All subsequent commands are placed in the display list,
in the order issued,
until
Gl.EndList is called.
Gl.NewList 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
Gl.GenLists
and tested for uniqueness with
Gl.IsList.
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
Gl.AreTexturesResident,
Gl.ColorPointer,
Gl.DeleteLists,
Gl.DeleteTextures,
Gl.DisableClientState,
Gl.EdgeFlagPointer,
Gl.EnableClientState,
Gl.FeedbackBuffer,
Gl.Finish,
Gl.Flush,
Gl.GenLists,
Gl.GenTextures,
Gl.IndexPointer,
Gl.InterleavedArrays,
Gl.IsEnabled,
Gl.IsList,
Gl.IsTexture,
Gl.NormalPointer,
Gl.PopClientAttrib,
Gl.PixelStore,
Gl.PushClientAttrib,
Gl.ReadPixels,
Gl.RenderMode,
Gl.SelectBuffer,
Gl.TexCoordPointer,
Gl.VertexPointer,
and all of the
Gl.Get commands.
Similarly,
Gl.TexImage1D, Gl.TexImage2D, and Gl.TexImage3D
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 ARB_imaging extension is supported,
Gl.Histogram executes immediately when its argument is
Gl.PROXY_HISTOGRAM. Similarly, Gl.ColorTable executes
immediately when its first argument is Gl.PROXY_COLOR_TABLE,
Gl.PROXY_POST_CONVOLUTION_COLOR_TABLE, or
Gl.PROXY_POST_COLOR_MATRIX_COLOR_TABLE.
For OpenGL versions 1.3 and greater, or when the ARB_multitexture extension is supported,
Gl.ClientActiveTexture is not compiled into display lists, but
executed immediately.
When Gl.EndList is encountered,
the display-list definition is completed by associating the list
with the unique name
list
(specified in the
Gl.NewList command).
If a display list with name
list already exists,
it is replaced only when Gl.EndList is called.
Notes
Gl.CallList and
Gl.CallLists can be entered into display lists.
Commands in the display list or lists executed by Gl.CallList
or Gl.CallLists 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
Gl.EndList is called
without a preceding
Gl.NewList,
or if
Gl.NewList is called while a display list is being defined.
Gl.INVALID_OPERATION is generated if
Gl.NewList or Gl.EndList
is executed between the execution of
Gl.Begin
and the corresponding execution of
Gl.End.
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.)
Associated Gets
Gl.IsList
Gl.Get with argument Gl.LIST_INDEX
Gl.Get with argument Gl.LIST_MODE
