<p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have 3D cardiac MRI data (4D including time domain). I can display volume rendering of the data using vtkSmartVolumeMapper.</p>
<p class="MsoNormal">When I tried to do animation (CINE) by changing actors every time TimerEvent occurs, it is slow (using CPU or GPU).
</p>
<p class="MsoNormal">Even when there is no user interaction, vtk seems to perform volume rendering every time actors change.</p>
<p class="MsoNormal">Are there any way for vtk to not perform volume rendering every time actors change by caching or something?</p>
<p class="MsoNormal">I was wondering if vtkMultiBlockDataSet or vtkTemporal*** can be utilized, but was unable to find a solution.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thank you,</p>
<p class="MsoNormal"> </p>
