Re: [Paraview] Problem with Custom ParaView Reader
Hi Kalin, I'm thinking that maybe there is ghost level information that is wrong, or maybe extent information. I'm assuming that you're running the server in serial so in that case you shouldn't have any ghost levels. If your grid has 16 points in each direction than than the extent for that should be [i, i+15, j, j+15, k, k+15] for a single process (note that extents don't need to start from 0 but usually do). If your grid is 16 cells in each direction than the extent would be [i, i+16, j, j+16, k, k+16]. If that isn't the problem, dan you share your code and your vti file from your test harness?

Re: [Paraview] Problem with Custom ParaView Reader
Hi Andy,
Thanks for the quick response. I am setting the extent to be
[0,16,0,16,0,16], as follows:
in the constructor:
this-extent[0] = 0;
this-extent[1] = 16;
this-extent[2] = 0;
this-extent[3] = 16;
this-extent[4] = 0;
this-extent[5] = 16;
in RequestInformation():
outInfo-Set(
vtkStreamingDemandDrivenPipeline::
WHOLE_EXTENT(),
this-extent, 6);
Attached is the .vti file and the code. In the test harness I also have
a vtkRenderer, which also displays the data as a 3d cube.

Re: [Paraview] Problem with Custom ParaView Reader
Hi Kalin,
I think the issue is that your extents are wrong. The extents should be the
index of the first and last point in each logical direction so it should be
[0, 15, 0, 15, 0, 15] if you have a square grid with 4096 points. Note that
this is the whole extent that the reader could provide even though
subsequent filters may ask for a reduced extent. Also, in RequestData() you
should get the requested extent with something like the following and take
out the SetDimension() call:
vtkInformation *outInfo = outputVector-GetInformationObject(outputPort);
int subext[6];
outInfo-Get(vtkStreamingDemandDrivenPipeline::UPDATE_EXTENT(),subext);
image-SetExtent(subext);
Then use the subextent to fill in your scalars array since it may be less
than what it could potentially provide (e.g. why read in all data when you
only need a subset of that).
I've filled in the vtkJHTDBReader.cxx code with some comments and changes.
You should go through and review what I did since I can't test your code.

Andy

[Paraview] Outline of multiple transforms
Hi all, I was curios to know if it is possible to draw an outline around several transformed domains. I have run a simulation of s periodic flow on a truncated domain. Upon importing the data, have added a couple of transformations to give the impression of a wider domain. However, unlike reflect, which merges copies of the original and mirrored domain, the transforms are separate items in the pipeline. I'm not sure how to draw a single outline around the original and transform domains. I would appreciate any advice.

[Paraview] VRUI connection ParaView Crash
Hi, after some time in which i had to dedicate myself to other software, i finally had a chance to come back to paraview to work and develop on it. I'm trying to re-set it up on my 3-screens VR setup with magnetic tracking of the user position and wand and a wiimote to get the buttons. I have a VRUI server that joins the tracker and the wiimote, but there seems to be no way to get it working in ParaView. I tried with a VRPN server and it works correctly, tracking and all, but unfortunately i need the VRUI one to join buttons. As soon as i configure everything in the VRPlugin (i tried both ways, through the GUI and through the state file) and I start it, paraview gets stuck, mouse pointer hourglass shaped and no sign of life nor error message until i have to kill the process. I tried with the 3.98 and the 4.0, with the 4.1 i seem to have a mismatching between the client and server version and therefore the handshake seems to fail because of that. Any idea?
