[Paraview] Populating "transforming" entries in a reader

Hi everyone, I'm interested in the possibility of automatically populating the entries in the "transforming" options of an object from within a reader (specifically the nifti reader). I've not been able to track down where these entries live in the class hierarchy, or whether it is feasible based o

[Paraview] Fixing the nifti plugin

Hi Everyone, I'd like to use paraview to combine volume rendering with various forms of geometric information - meshes and streamlines. The volume information is typically in the form of nifti files, while the geometries are VTK files. My problem is that the nifti plugin doesn't fully utilize the n

[Paraview] Tube on line problem solved

Hello, My previous issue with applying the tube filter to polydata lines has been solved, although there may be a bug that can be looked at in future releases. The problem came up on a linux machine on which the drop down filter menu stretched required scrolling. The Tube filter is well down this

[Paraview] Strange tube behaviour

Hi, I'm finding inconsistent behaviour between mac 4.0.1 (binary install) and linux 4.0.1 which I compiled myself. The issue is to do with applying the tube filter. I load a streamline dataset (which is an ascii vtk polydata file) - these streamlines are from MRI brain data, not fluid simulations.

[Paraview] Problems positioning image slices in 3D

Hi, I have a set of slices extracted from a 3D volume. These slices have been processed with image magick to produce a transparent background and a colour overlay. I can load several into paraview, feed them through the image to pointset filter and then transform them so that they are in a 3D stack

[Paraview] Further questions regarding 4D dataset

Hi, The volume rendering works successfully. Thank you for the assistance. Further investigations have suggested that Imaris is probably performing simple maximum intensity projection, but enabling the user to rotate the volume and producing nice colour combinations. Is there any MIP facility in pa

[Paraview] Recommendations for display of 4D color dataset

Hi, I'm investigating methods for display of a 4D microscopy dataset. I'd like to be able to reproduce the style of display provided by Imaris, however I'm not entirely sure how Imaris does it. It may be volume rendering or a clever surface rendering. The data is from a confocal microscope and has

[Paraview] Viewing of 3D image data on object data with paraview

Hi, I asked a related question a couple of years ago but never found a good answer. I need to revisit it now. I'd like to view image data plus track data in paraview. The track data is produced as list of points in world coordinates. I can convert these to vtk objects and load them. My problem is

Re: [Paraview] Problems combining volume and line data

solution is to translate the direction cosines into an orientation that can be entered into paraviews transformation. I am still stuck with how to colour lines according to direction though. Thanks On Fri, Oct 1, 2010 at 2:13 PM, Richard Beare wrote: > Hello, > I have some image data that I'd

[Paraview] Problems combining volume and line data

Hello, I have some image data that I'd like to volume render. It starts out as a nifti file and I can view it in paraview after conversion to a vtk structured grid (using the ITK ConvertBetweenFileFormats tool). I also have some line data (DTI tracts) that I have converted to ploydata lines. I can

[Paraview] help with streamlines (units?)

Hi, I'm hoping to examine some MRI derived blood flow velocity data using paraview. I've transformed the original data into a time series of vtk images, which have the velocity vector at each point. However I suspect I need to set up the units for velocity appropriately. Should I ensure that the di

[Paraview] paraview as a mesh editor?

Hi, I was wondering whether there are any options that allow some interactive editing of mesh objects in paraview? Is this a capability that can be included in the existing pipeline structure or is it completely outside the design. My reason for thinking about paraview for this application is that

[Paraview] Viewing multiple image volumes that aren't in the same space

Hi, I have some slice based MRI data that I'd like to display in paraview (so I can do contouring and so on). I have multiple slices in different planes that I'd like to display in their correct relative positions. The problem is that paraview appears to ignore all of the orientation information,
