Hi..<br>I listen to your suggestion, but I think thath glColorMask can be used only after this instruction: myVtkRenderWindow->Render(); ...is it right?<br>So glColorMash is applyed at all scene while I'd like to use glColorMask only for a particular actor (a kind of box which serves as a mask).<br>Whath do you think about this?<br>Thanks a lot...<br><br>Luca<br><br><hr id="EC_stopSpelling">Date: Tue, 26 May 2009 12:45:54 -0400<br>Subject: Re: [vtkusers] call glColorMask from vtk<br>From: utkarsh.ayachit@kitware.com<br>To: luca.ramundo@hotmail.it<br>CC: vtkusers@vtk.org<br><br>Try implementing your own mapper or actor. You can make openGL calls in Render methods in these classes.<br><br>Utkarsh<br><br><div class="EC_EC_gmail_quote">On Tue, May 26, 2009 at 10:48 AM, Luca Ramundo <span dir="ltr"><<a href="mailto:luca.ramundo@hotmail.it">luca.ramundo@hotmail.it</a>></span> wrote:<br>

hi all,<br>I need your help for my great problem. I'd like to visualize a 3D object in my scene with the follow properties:<br>It must to be invisible but not trasparence because it has to hide some object inside it.<br>
I know that there is a openGL method to do it: glColorMask(). It is used to write or not in frame buffer some color component.<br>I'd like if there is something to resolve my problem in VTK or the way to call this openGL method from my vtk object.<br>
Thanks a lot,<br>Luca<br><hr>Quali sono le parole più cliccate? <a href="http://livesearch.it.msn.com/">Scopri la top!</a></div>
