<P>Hello,</P>
<P>We are developing a 3D CFD data visualization tool using vtk.</P>
<P>We recently shifted from vtk 4.0 to 4.2 and now have the following
problem:</P>
<P>Setting the pixelaspect on the viewport (in this case the renderer) used to
result in views with different aspect ratios (which is useful for us, because
our datasets tend to be much wider than tall).</P>
<P>But now, with vtk 4.2 this doesn't work anymore, although some 2D actors
behave as desired and the interactorstyle seems to change its behaviour.</P>
<P>We tried to find the problem in the vtk sources and the aspect setting seems
to influence the results of WorldToDisplay but we couldn't find any obvious
reasons why this wouldn't work correctly. It's probably to deep down into the
rendering process for us. Hope someone can help us out.</P>
<P>Kind regards,</P>
<P>Pink and Titus</P></FONT></FONT></DIV></BODY></HTML>
