<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Let’s take a very simple example to explain the encountered problem.<o:p></o:p></p>
<p class="MsoNormal">The considered model has only four points and a single cell (a quad basically).<o:p></o:p></p>
<p class="MsoNormal">The extraction point is a triangle cell using the bottom-left point, so half of the quad is in the extraction point.<o:p></o:p></p>
<p class="MsoNormal">As the points are the same in the model and the extraction points, the two cells are superimposed.<o:p></o:p></p>
<p class="MsoNormal">If we consider that the model is colored with default color and the extraction point is colored with blue, the rendering won’t be as expected : it is kind of hatched rendering.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">Thank you for your help.<o:p></o:p></p>
