1/22/2024 0 Comments Paraview web![]() ![]() Loading data remotely with vtk.web protocols which consists of data folder with multiple file-formats like DICOM and mhd/mha. Is there any advantage(provide better color maps to the data which gives a more realistic volume rendering effect) of doing the same thing with paraview python rather than vtk, considering my use case. So, my approach is the vtk.web protocols and the normal vtk pipeline as I’m more comfortable with it for remote volume rendering and mpr and itk for segmentation. But, my interest is only on loading data from the server side and choosing the required data to visualize, basically web based remote volume rendering, then modifying the existing client side and the server side to support only remote volume rendering and later adding mpr and segmentation to it is very challenging and time consuming. I have a last few couple of major questions to ask you.Īctually, the Paraview Visualizer is an amazing example of doing the same thing as the paraview desktop application. I tried that and I was able to get the different render windows using GetGlobalId(), typecast to str, pass those ids as a list to a custom protocol, override VtkImageDeliveryProtocol and was able to access them in the client side with the view id. That answer was exactly to the point and that exactly gave me the answer I was looking for. So, how do you suggest I approach this MPR given the current pipeline, any advice is appreciated. I don’t understand how the mapper is being setup in the paraview vizualizer pipeline. The, Paraviewweb mouse handler sets up the “renderWindowInteractor”. ![]() Then, the registered viewport acts as a “renderwindow”. The, vtkRenderer/vtkGeometry renderer in paraviewweb adds the actor to it based on viewId. I’m trying to wrap my head around it by comparing it to the VTK pipeline.Ĭhoosing the data on the client side, sets up the “Reader” with the required data.Ĭhoosing Volume, Slice, etc from the drop-down sets up the “Actor”. I also don’t fully understand how Volume rendering is taking place here, when you click Volume from the drop-down. ![]() I understand the general pipeline of Visualizer, an entire directory is registered, so the user can choose the data on the client side and based on his need he can choose to Slice, Surface or Volume render, etc and after choosing based on mouse events, those mouse events are updated to the server and the data gets rendered and the updated images get sent back to the client. Here, we load one specific data and do MPR on it. So, if this is the case and I want to perform MPR, creating 3 more viewports one for each axial, coronal and saggital views will do I guess.īut, I’m not sure how to do this or even how to get started. So, based on the data size, 3d reconstruction happens on the server/client side and the user just gets a way to interact with the data with mouse events. Right now, if my understand is correct, by looking at the Paraview Vizualizer’s server code, a viewport is registered, so it can be accessed on the client side in vtkRenderer as a unique viewId. Say in a different viewport display the axial, coronal and saggital views for the chosen data. I’m also interested to know if it’s there’s any way to integrate Multi planar reconstruction(MPR) with it. Also, I’m aware that Paraview Visualizer is just an example of what is possible with paraview web, reactjs and pvpython, but I really like the remote rendering functionality so I don’t really want to re-invent the wheel, starting from scratch. ![]() Hi, I was able to build Paraview visualizer code and test out the remote volume rendering functionality. ![]()
