You may want to read this source article: <a href="http://www.kitware.com/source/home/post/154" target="_blank">http://www.kitware.com/source/home/post/154</a>. Most of the changes related to this work is now available in VTK github repository in master branch. If you are targetting current VTK, I would suggest that any card that can support OpenGL2.1 or higher would be great. The higher the GPU memory the better. While these newer card will work with the previous version of volume rendering, it may not scale very well (in our testing that's what we have observed). Current the default in ParaView is OpenGL Volume Rendering but that is going to change sometime soon and once that happens you will have OpenGL2 backend for everything. </div><div><br></div><div>Hope this helps. </div><div>- Aashish</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div>On Thu, Feb 26, 2015 at 5:41 PM, Kevin Lau <span dir="ltr"><<a href="mailto:kevin.d.lau@gmail.com" target="_blank">kevin.d.lau@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div><div><div dir="ltr"><div><div>Hi, <br><br></div>I'm looking to putting together a workstation to perform realtime volume rendering of our simulation data.<br><br></div><div>Are there any particular GPU features I should look for? <br><br></div><div>If there are multiple GPUs will Paraview be able to take advantage of each GPU for volume rendering?<br><br></div><div>Many thanks<span><font color="#888888"><br><br></font></span></div><span><font color="#888888"><div>Kevin<br></div><div><br></div><br></font></span></div>
