Hi,<br><br>Concerning coordinate systems, the visualization pipeline is what is of interest for you. You won't find useful stuff in ParaView sources (well, except for some helper classes or wrap-around VTK) but instead you should take a look at VTK sources. There, you will find a vtkCamera class and vtkTransform filters, but also coordinate systems correspondances in vtkRenderer, vtkMapper, ... ie everything that has role in the visualization pipeline.<br>
<br>Sorry for the lack of precisions, but I hope that'll help...<br>Jerome<br><br><div class="gmail_quote">2009/9/25 Arsham Mesbah <span dir="ltr"><<a href="mailto:arsham@uga.edu">arsham@uga.edu</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Hi<br><br>Does anyone know how different coordination systems is being handled in ParaView and How paraview keeps track of the the transformation from one to another one! <br>Here is my train of thoughts, well in any 3D Visualization system we have a "Point of View" which I think in ParaView is handled with a Class (ParaView uses the term Camera I think) which I assume it is in a different coordinate system than Our actual scene! (I would actually like to know name of and the location of the camera class in ParaView Source if you know where it is please do let me know) <br>
Further more, we might have more than an object which we are visualizing (reading off of vtk file) and they might be in different coordinate systems how does ParaView handle this? which class is used to handle this kind of differences and how ParaView keeps the track of these transforms? Any specific Proxy or Super class is used here to handle this? <br>
<br>I would appreciate any help or comment! <br clear="all"><font color="#888888"><br>-- <br>Sincerely Yours,<br>Arsham Mesbah<br>University of Georgia<br>Department of Computer Science<br>415 Graduate Studies Research Center<br>
