<para>
|
|
Display lists are groups of GL commands that have been stored
|
|
for subsequent execution.
|
|
Display lists are created with <function>glNewList</function>.
|
|
All subsequent commands are placed in the display list,
|
|
in the order issued,
|
|
until <citerefentry><refentrytitle>glEndList</refentrytitle></citerefentry> is called.
|
|
</para>
|
|
<para>
|
|
<function>glNewList</function> has two arguments.
|
|
The first argument,
|
|
<parameter>list</parameter>,
|
|
is a positive integer that becomes the unique name for the display list.
|
|
Names can be created and reserved with <citerefentry><refentrytitle>glGenLists</refentrytitle></citerefentry>
|
|
and tested for uniqueness with <citerefentry><refentrytitle>glIsList</refentrytitle></citerefentry>.
|
|
The second argument,
|
|
<parameter>mode</parameter>,
|
|
is a symbolic constant that can assume one of two values:
|
|
</para>
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term><constant>GL_COMPILE</constant></term>
|
|

Commands are merely compiled.

<varlistentry>

<term><constant>GL_COMPILE_AND_EXECUTE</constant></term>
|
|
<listitem>

<para>

Commands are executed as they are compiled into the display list.
|
|
</para>
|
|
</listitem>
|
|
</varlistentry>
|
|
</variablelist>
|
|
<para>
|
|
Certain commands are not compiled into the display list
|
|
but are executed immediately,
|
|
regardless of the display-list mode.
|
|
These commands are
|
|
<citerefentry><refentrytitle>glAreTexturesResident</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glColorPointer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glDeleteLists</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glDeleteTextures</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glDisableClientState</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glEdgeFlagPointer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glEnableClientState</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glFeedbackBuffer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glFinish</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glFlush</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glGenLists</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glGenTextures</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glIndexPointer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glInterleavedArrays</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glIsEnabled</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glIsList</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glIsTexture</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glNormalPointer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glPopClientAttrib</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glPixelStore</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glPushClientAttrib</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glReadPixels</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glRenderMode</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glSelectBuffer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glTexCoordPointer</refentrytitle></citerefentry>,
|
|
<citerefentry><refentrytitle>glVertexPointer</refentrytitle></citerefentry>,
|
|
and all of the <citerefentry><refentrytitle>glGet</refentrytitle></citerefentry> commands.
|
|
</para>
|
|
<para>
|
|
Similarly,
|
|
<citerefentry><refentrytitle>glTexImage1D</refentrytitle></citerefentry>, <citerefentry><refentrytitle>glTexImage2D</refentrytitle></citerefentry>, and <citerefentry><refentrytitle>glTexImage3D</refentrytitle></citerefentry>
|
|
are executed immediately and not compiled into the display list when their
|
|
first argument is <constant>GL_PROXY_TEXTURE_1D</constant>, <constant>GL_PROXY_TEXTURE_1D</constant>, or
|
|
<constant>GL_PROXY_TEXTURE_3D</constant>, respectively.
|
|
</para>
|
|
<para>
|
|
When the <code>ARB_imaging</code> extension is supported,
|
|
<citerefentry><refentrytitle>glHistogram</refentrytitle></citerefentry> executes immediately when its argument is
|
|
<constant>GL_PROXY_HISTOGRAM</constant>. Similarly, <citerefentry><refentrytitle>glColorTable</refentrytitle></citerefentry> executes
|
|
immediately when its first argument is <constant>GL_PROXY_COLOR_TABLE</constant>,
|
|
<constant>GL_PROXY_POST_CONVOLUTION_COLOR_TABLE</constant>, or
|
|
<constant>GL_PROXY_POST_COLOR_MATRIX_COLOR_TABLE</constant>.
|
|
</para>
|
|
<para>
|
|
For OpenGL versions 1.3 and greater, or when the <code>ARB_multitexture</code> extension is supported,
|
|
<citerefentry><refentrytitle>glClientActiveTexture</refentrytitle></citerefentry> is not compiled into display lists, but
|
|
executed immediately.
|
|
</para>
|
|
<para>
|
|
When <citerefentry><refentrytitle>glEndList</refentrytitle></citerefentry> is encountered,
|
|
the display-list definition is completed by associating the list
|
|
with the unique name <parameter>list</parameter>
|
|
(specified in the <function>glNewList</function> command).
|
|
If a display list with name <parameter>list</parameter> already exists,
|
|
it is replaced only when <citerefentry><refentrytitle>glEndList</refentrytitle></citerefentry> is called.
|
|
</para>

<para>
|
|
<citerefentry><refentrytitle>glCallList</refentrytitle></citerefentry> and <citerefentry><refentrytitle>glCallLists</refentrytitle></citerefentry> can be entered into display lists.
|
|
Commands in the display list or lists executed by <citerefentry><refentrytitle>glCallList</refentrytitle></citerefentry>
|
|
or <citerefentry><refentrytitle>glCallLists</refentrytitle></citerefentry> are not included in the display list being created,
|
|
even if the list creation mode is <constant>GL_COMPILE_AND_EXECUTE</constant>.
|
|
</para>
|
|
<para>
|
|
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 <constant>GL_COMPILE</constant> mode, errors are
|
|
not generated until the list is executed.

<para>
|
|
<constant>GL_INVALID_VALUE</constant> is generated if <parameter>list</parameter> is 0.
|
|
</para>
|
|
<para>
|
|
<constant>GL_INVALID_ENUM</constant> is generated if <parameter>mode</parameter> is not an accepted value.
|
|
</para>
|
|
<para>
|
|
<constant>GL_INVALID_OPERATION</constant> is generated if <citerefentry><refentrytitle>glEndList</refentrytitle></citerefentry> is called
|
|
without a preceding <function>glNewList</function>,
|
|
or if <function>glNewList</function> is called while a display list is being defined.
|
|
</para>
|
|
<para>
|
|
<constant>GL_INVALID_OPERATION</constant> is generated if <function>glNewList</function> or <citerefentry><refentrytitle>glEndList</refentrytitle></citerefentry>
|
|
is executed between the execution of <citerefentry><refentrytitle>glBegin</refentrytitle></citerefentry>
|
|
and the corresponding execution of <citerefentry><refentrytitle>glEnd</refentrytitle></citerefentry>.
|
|
</para>
|
|
<para>
|
|
<constant>GL_OUT_OF_MEMORY</constant> 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.)
