I am trying to visualize an isosurface. I used to work with Matlab where I would input the data in 4D in the format: <X> <Y> <Z> <Intensity><br>To use Paraview, I generated a dataset in VTK format as an unstructured grid with no cells. The Intensities are associated to the corners of the cells as follow:<br><br><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 11"><meta name="Originator" content="Microsoft Word 11"><link rel="File-List" href="file:///C:%5CUsers%5Calex%5CAppData%5CLocal%5CTemp%5Cmsohtml1%5C01%5Cclip_filelist.xml"><!--[if gte mso 9]><xml>
