Re: [Paraview] Can Paraview use the GPU instead of the CPU?
" Thank you Mathieu for your reply. Regarding point 2 I have few questions: 1. I see the volume rendering mode (which I can switch between smart and CPU based) when I select a wavelet for instance. However, I can't see it when I choose unstructured cell type as the source (and this applies to my data set coming from CFD results). In that latter case, I get the select mapper drop down menu which has the options of projected tetra/z sweep/bunyk ray cast/resample to image. Is there a way to ensure volume rendering is done using the GPUs in that case? 2. In the case described above, when I select resample to image, the color of the model gets messed up (it becomes one color). Is there a way to get it back to normal? Thanks." Also, a third question regarding this point. If Paraview can do volume rendering using the GPUs. What does the NVIDIA IndeX plugin add on top of that then?

[Paraview] Can Paraview use the GPU instead of the CPU?
Is there a way to use the GPU instead of the CPU for: 1. Data rendering in general? 2. Volume rendering? other than using the NVIDIA IndeX plugin? 3. Loading and displaying the data (i.e. data crunching). For example, if I am loading a transient CFD simulation result? Also, is there a way to render-off screen through Paraview GUI? or this needs to be done through code? -- Best Regards, Mohamed Beshr ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: https://public.kitware.com/mailman/listinfo/paraview
