glNewList.3gl

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.	 The 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
  glIsList, glGenLists,	glDeleteLists, glFeedbackBuffer, glSelectBuffer,
  glRenderMode,	glReadPixels, glPixelStore, glFlush, glFinish, glIsEnabled,
  and all of the glGet routines.

  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.	 The 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 zero.

  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.
