And how can I mange to unite three different actors on one single

<br>
one option is you can use vtkThreshold, if your threshold ranges are
fiixed.. Like in your example, there are three conditions.. So three
times, u can use vtkThreshold class and create that many actors..<br>
<br>
Any other way is there my friends..??<br>
<br>
Thanks<br>

Do you know if it's possible to assign different alpha values to a
scalar field representation (for example on a cutting plane)?<br>
<br>
I want to have scalar to be more transparent if they are below some
defined threshold.<br>
For example something like this<br>
</font></font>
<ul>
<li><small><font face="Helvetica, Arial, sans-serif">scalar
<
0.1
: alpha = 0.3</font></small></li>
<li><small><font face="Helvetica, Arial, sans-serif">0.1 <
scalar
< 0.5 : alpha = 0.7</font></small></li>
<li><small><font face="Helvetica, Arial, sans-serif">scalar
>
0.5
: alpha = 1.0</font></small></li>
</ul>
<font face="Helvetica, Arial, sans-serif"><small>Do you know
how I
can
manage this?</small><br>
<br>
