Yes when you rotate, a coarse resolution mesh is used to keep the interaction in real time . You can try GPURayCastMapper for batter performance but I am not sure if the interaction will be done on its original resolution <br>

Hi everyone<br>Sorry for my numerous questions but I'm new in vtk and so I have several doubts.<br><br>I'm using vtkVolumeRayCastCompositeFunction (as I said in my other mails) to render a 3D volume. <br>Is it normal that, when I move the mouse on my OpenGL Window, the image losses focus and resolution and takes a little time to return ok? Or is it a problem of my pc? Is there any way to improve my OpenGL performance?<br>
<br>Thanks<br>Daniela<br> <br><hr>nome.cognome @... Verifica la disponibilità sui <a href="https://signup.live.com/signup.aspx?mkt=it-it&rollrs=12&lic=1" target="_blank">NUOVI domini</a></div>
