<p>
</p>
<p>With this module, it is possible to colorize nodes depending
on data read in an input file. An input file can be associated to a
<a class="link" href="v-sim-visu-data.html#VisuData"><span class="type">VisuData</span></a> object using <a class="link" href="v-sim-dataFile.html#dataFileSet-file" title="dataFileSet_file ()"><code class="function">dataFileSet_file()</code></a>. Doing this, the
rendering is changed and nodes are colorized following a scheme
describe later. To turn off colorization without removing the data
file (for temporary turn off for instance), use
<a class="link" href="v-sim-dataFile.html#dataFileSet-used" title="dataFileSet_used ()"><code class="function">dataFileSet_used()</code></a>.</p>
<p>
</p>
<p>The input file must have the same numbers of uncommented
lines as there are nodes in the <a class="link" href="v-sim-visu-data.html#VisuData"><span class="type">VisuData</span></a> associated with. If less
data is given, missing data are treaded as min values data. The
input data file can has as much column as desired. The colorization
is based on a linear color transformation. This transformation is
applied on color channel in RGB mode or in HSV mode. Resulting
color is given by : [resulting color vect] = [vectB] + [input
data][vectA], where [input data] are input data scaled to [0;1]. It
is possible to choose which column multiplies which color
channel.</p>
<p>
</p>
<p>Using <a class="link" href="v-sim-dataFile.html#dataFileApply-hideOnMinValue" title="dataFileApply_hideOnMinValue ()"><code class="function">dataFileApply_hideOnMinValue()</code></a>, it is possible to hide
some nodes depending on given input data. If the <em class="parameter"><code>column</code></em> argument
is -1, it unmask all nodes.</p>
