Paraview 5.6 black screen12/18/2023 ![]() We changed the clipping planes at vtkCamera::ComputeOffAxisProjectionFrustum(), when the projection matrix is being defined: But you should be able to see the full volume rendering on the server windows. To clarify, in CAVE mode, the client will never show the volume rendering, only outlines. Here is the state file and the dataset I used for the test: ironprotein.7z (68.4 KB) I can debug that further, but want to see if this is a reasonable approach before investigating it much further. In my test done using this cave.pvx (413 Bytes) and the Wavelet source or ironProtein dataset from ParaView data, I can see the volume mostly okay except for a few angles – I suspect it the clipping planes are not setup correctly due to bounds mismatch or something like that. InInfo.Set(executive.UPDATE_PIECE_NUMBER(), 0) InInfo.Set(executive.UPDATE_NUMBER_OF_PIECES(), 1) InInfo.Set(executive.UPDATE_EXTENT(), we, we, we, we, we, we) RequestUpdateExtent Script executive = self.GetExecutive() ![]() OutInfo.Set(executive.WHOLE_EXTENT(), we, we, we, we, we, we) We = inInfo.Get(executive.WHOLE_EXTENT()) InInfo = executive.GetInputInformation(0, 0) OutInfo = executive.GetOutputInformation(0) RequestInformation Script executive = self.GetExecutive() Print ("local extents are: ", input0.GetExtent()) Script # just for debugging, can be left empty For that, create the Programmable Filter connected to your ctVolume.vti source and add the following scripts for the 3 inputs on the Properties panel (you’ll need to click the on the Properties panel to see all properties) in addition to checking the Copy Arrays checkbox. The following Programmable filter script can be used to force ParaView to duplicate the data on all ranks. Is there any way we can add code to replicate our volume data so that it will work? IndeX takes advantage of the computational horsepower of GPUs to deliver real-time performance on large datasets by distributing visualization workloads across a GPU-accelerated cluster. On the other hand, when loading volume data, and switching the data representation from outline to volume, it prints Remote/parallel rendering: yesĪdditionally, we just realized there is an nvidia plugin for paraview: When loading vertex data(or just displaying the default empty scene) it prints : Remote/parallel rendering: no. I enabled the Show Annotation option, and I noticed two things. We are running a CAVE system using paraview immersive. So it seems the description I gave in the main post is wrong. I see, that’d explain the outline voxels on the desktop application! In the cave display nodes we see parts of the volume distributed all over the place, and some parts are not even renderer, it’s really hard to take a picture of it to show you. ![]() If you’re in CAVE mode, then the visualization shown in the application is only a representative and hence you won’t see the volume rendering in the desktop application. The other nodes dont throw any error messages related to displays and connections. VtkPVServerInformation::GetOGVSupport was deprecated for ParaView 5.5 and will be removed in a future version. Generic Warning: In /gpfs/runtime/opt/paraview/5.6.0_OpenGL2/src/Paraview/ParaViewCore/ClientServerCore/Core/vtkPVServerInformation.cxx, line 784 This is the generated output when the system connects from the desktop to the server: Is there a best practice manual on how to handle this distribute rendering case? Maybe there is an option we need to enable or an extra library Paraview needs to be built with.Īlso, this a Linux environment and every node has a Quadro K5000 card. The data is only 6.8mb, so personally I dont think is related to ram /vram memory. ![]() Maybe paraview sends all the data to every node instead of dividing it into chunks and distribute them to all the system. Our theory is, there are problems related on how the data is handle on the different nodes. ![]() When Paraview is not connected to the server, it renders the data as showed here:īut when it’s connected to the server, we get these outlined transparent voxels: However, we found out that it doesnt render volume data properly. Our system has Paraview installed in a client/server distributed rendering cluster and set it up to do parallel rendering on 69 nodes ( we followed all the instructions in ). ![]()
