<a href="development_node_Inline.html">Inline node</a> dynamically load and
display a subscene file.<br/>
</p>
<p>
<a href="development_node_Inline.html">Inline node</a> can be use with the
<a href="development_node_Switch.html">Switch node</a>.<br/>
Advantage, only the displayed node is loaded in memory. Other subscenes are not
loader.<br/>
Inconvenience, change the subscene is slower (when <b>whichChoice</b> attribute
of Swith node change). Inline node must load and construct the new subscene.
</p>
<p>
The other possibility to define and display subscene: create and use a prototype
by sub scene.<br/>
Advantage, change the subscene is fast (subscene is already loaded).<br/>
Inconvenience, all subscene are loaded in memory.<br/>
</p>
<p>
The best solution, between use prototype or Inline node, depends on the material
constraints (memory, processor, ...) and the complexity of the scene.
</p>
<br/>

<p class="note info">
<b>Note:</b><br/>
MeMo extends <a href="development_node_Inline.html">Inline node</a> specification.<br/>
In addition, <a href="development_node_Inline.html">Inline node</a> gives you the opportunity to select a language pack for the
scene that is inlined.
</p>

<p class="note warning">
<b>Warning:</b><br/>
For Inline node, only use <span class="highlight">M4M</span> files in URL field.<br/>
Don't use <span class="highlight">WRL</span> files ( cause problems during the
final M4M file creation).
</p>
<br/>

<script type="text/javascript">addTitle("Anchor", 1);</script>

<p>
The <a href="development_node_Anchor.html">Anchor node</a> has two roles:
</p>
<ul>
<li>Call the phone browser and display a web page.<br/>
<p class="note info">
<b>Note:</b><br/>MicroEmulator doesn't open web browser.
</p>
</li>
<li>Open another VRML scene.<br/>
    <a href="development_node_Anchor.html">Anchor node</a> can change all the
    scene or only the Inline part containing the Anchor.
   <p class="note warning">
   <b>Warning:</b><br/>
   For Anchor node, to link scene with another scene, use <span class="highlight">M4M</span>

<script type="text/javascript">addTitle("Switch and resource saving", 1);</script>

<p>
<a href="development_node_Switch.html">Switch node</a> allows to render only
one node in a list of nodes. It is useful to display or hide elements.<br/>
It can be used to manage different panels in a scene (with tabs, menu, ...).<br/>
</p>
<br/>

<p>
<a href="development_node_Switch.html">Switch node</a> contains an array of
nodes (<b>choice</b> attribute) and the displayed node (<b>whichChoice</b> attribute).<br/>
<b>whichChoice</b> contains the index of current displayed node in <b>choice</b>
array. First node index is 0. <a href="development_node_Switch.html">Switch node</a>
doesn't display node if <b>whichChoice = -1</b>.<br/>
<b>whichChoice</b> value is modifiable via script (Script node and javascript language).
</p>

<p>
See <a href="development_node_Switch.html">Switch node documentation</a> for
more information about Swith node and example.
