At 1,000,000 voxels there are approximately 2 samples/voxel. Starting with 8 voxels there are approximately 200 samples/voxel. The number of samples seems to be auto generated. It is "the unit distance on which the scalar opacity transfer function is defined." I believe this is used to attenuate the OTF values, i.e., it's a hack to defer editing the CTF and OTF if possible. It is NOT the number of samples along the ray nor the distance between samples. This is an attribute of vtkVolumeProperty. The texture-based volume mappers were dropped at some point.vtkRectilinearGrid can have a Tetrahedralize filter applied to create an unstructured grid, though. vtkRectilinearGrid and vtkPolyData are not supported.It is not clear how using the "OSPRay Based" volume mapper differs from enabling OSPRay overall.It is unclear why one would use the "Resample to Image" volume mapper instead of applying a "Resample to Image" filter in the pipeline.VtkImageData, vtkStructuredPoints Volume Mappers Sampling Dimensions (Resample to Image only).vtkStructuredGrid, vtkUnstructuredGrid Volume Mappers Caveat: Responsive GUIĪfter selecting "Volume" from the Representation menu, the volume mappers made available in the Properties will depend upon the VTK Data Set type of the selected item in the Pipeline Browser.

ParaView can read in delimited text files as tables, which is essentially what you have.
