glNewList(3G) OpenGL Reference 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 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 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 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 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.)
