glNewList, glEndList
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 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,
glDeleteList,
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.
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 is called between
a call to glBegin and the corresponding
call to glEnd.
