[Paraview] Questions on Paraview with 3D vector fields

[Moreland, Kenneth]

Jim,

It looks like you are asking two questions.

The first question is about using the glyph filter. I'm not sure what the confusion is. The arrow glyph filter works equal well with polygons and polyhedral. I have no trouble loading in a 3D dataset with 3D cells and cell-centered data. I just select the arrow glyph and everything works fine. In short, I cannot replicate what your issue is. Perhaps you can give more information.

As far as a fly through, yes it is possible in ParaView although, admittingly, the controls are not very good. To add a camera path, first open the Animation View (View -> Animation View). Then add a track to the Animation View for "Camera, Follow Path". After that, double click the track to bring up the keyframes dialog. From there you can double click "Path..." to get yet another dialog box to edit the path. Click "Camera Position" and then click back to the main ParaView window to edit the camera path.

Subject: [EXTERNAL] [Paraview] Questions on Paraview with 3D vector fields

Hello All:

I'm working with 3D vector fields (2 of them in the same space) and want to do a fly through, set the center to be one of the arrow glyphs, and do some calculations on both fields using the calculator. I can't seem to do any of these. Any ideas?

It looks like the center selection was designed to work with polymeshes. 
The arrow glyphs just can't be selected. Is there any way to fake out Paraview and place something that the selector can see?

I saw fly through mentioned on some forum but no solution. I can place a line into my space. Is there some way to use the line as a camera path? 
I'm really interested in fly throughs in the program, not watching them as a movie. There's just too many things to change to make it a movie and not take forever to make/look at them.

The calculator looks like it only hooks up to one vector field at a time. Is there some object linking trick or running one field through an intermediate calculation that would make both fields visible to the calculator?

Any help appreciated.

-J
