<p>
Interpolators are VRML nodes that provide an output value depending on
</p>
<ul>
<li>an input value from 0 to 1</li>
<li>a list of keys</li>
</ul>
<br/>

<p>
A ROUTE from TimeSensor TO input value of interpolator starts the calculation of the output value. A ROUTE from the output value of interpolator TO a field of another node will animate this field.
</p>
<br/>

<p>
There is one kind of interpolator per field type. There are several supported interpolators in the MeMo:
</p>
<ul>
<li><a href="development_node_ColorInterpolator.html">ColorInterpolator</a></li>
<li><a href="development_node_CoordinateInterpolator.html">CoordinateInterpolator</a></li>
<li><a href="development_node_CoordinateInterpolator2D.html">CoordinateInterpolator2D</a></li>
<li><a href="development_node_OrientationInterpolator.html">OrientationInterpolator</a></li>
<li><a href="development_node_PositionInterpolator.html">PositionInterpolator</a></li>
<li><a href="development_node_PositionInterpolator2D.html">PositionInterpolator2D</a></li>
<li><a href="development_node_ScalarInterpolator.html">ScalarInterpolator</a></li>
</ul>
<br/>

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

<p>
All these interpolators share a common interface and behavior.
</p>
<br/>

<p>
Every interpolator has the following fields:
</p>
<ul>
<li>the <b>set_fraction</b> field</li>
<li>the <b>value_changed</b> field</li>
<li>the <b>key</b> field</li>
<li>the <b>keyValue</b> field</li>
</ul>
<br/>
