<p class=MsoNormal><span lang=EN-US>Hi,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’d like to measure and display the
render time (or the frames per second). As this is probably a very common
problem I hope you can share your experience with me. This is what I found out
so far:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US> A good starting point seems to be the
vtkRenderer::GetLastRenderTimeInSeconds() method. However, there are two issues
left when using this method.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>In my application the vtkRenderWindow is
connected to a vtkRenderWindowInteractor. I’d like to display the FPS
without altering the vtk code. The vtkRenderWindowInteractor invokes the
RenderEvent after rendering. Is it possible to catch this event in my code and
the read the render time from vtkRenderWindow? If so, how?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’d also like to know the render time
of different actors in the scene. More specifically, I have a volume that is
rendered and I’d like to measure the render time just for the volume and
not for the others actors in the scene. Is that possible?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thank you very much in advance!<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Kindest regards,<o:p></o:p></span></p>
