Re: [Paraview] Changing default representation for vtkImageData
Oh no, don't need to add a new representation. You'll create a new autostart plugin (http://www.paraview.org/Wiki/Plugin_HowTo#Autostart_Plugins). In this plugin you'll have to create a new subclass for pqDisplayPolicy and then set it on the application core as follows: pqApplicationCore::instance()-setDisplayPolicy(mypolicy); In your pqDisplayPolicy subclass you can override the behaviour for creating representations when a new source is created.

Hey Utkarsh, No, I've never seen the clip lose data on one dataset by itself.

It's much more likely to disappear when the data was generated by a filter or brought in by a reader.

Re: [Paraview] Question on distributed processing and rendering using Paraview and MPI
Chewping,
Let me start with a nomenclature normalization. What you call master/slave
nodes we call client/server nodes. We make this distinction because the client
needs to be nowhere near the server nodes (I have attached a client to a server
running on the other side of the country).
Your question is difficult to answer succinctly because it depends on the type
of data. In general, load balancing does not happen through MPI but through
file I/O. The parallel readers in ParaView each read in a partition of data,
and that partition is fixed to the process. For structured types of data (data
with a regular grid topology), this partitioning can be very even. For
unstructured data, the partitioning is usually limited to how the data is lain
out in the data files, so even partitioning is not guaranteed. There is a
filter, D3, that will use MPI to redistribute an unstructured data set. No
data is passed through the client in this process.
For more information, you can consult The ParaView Guide, which has a couple of
chapters on parallel processing and rendering:
http://www.kitware.com/products/books.html
You may also take a look at the Supercomputing tutorial, which talks about the
parallel visualization from a User's perspective:

Hi,
My name is chewping and I'm doing my master's research in the University of
Malaya, Malaysia. I'm using ParaView and MPI to visualize a relatively large
medical data set in a homogeneous cluster environment. It consists of one
master node and 9 slave nodes in a Local Area Network with class C IP address.
Most nodes are similar to each other (32 bits processor, running on Linux). I
would like to manipulate MPI to make the performance better (faster
distributions of data and collections of results). As I am new to MPI and
parallel processing system, there are a few questions that I would like to ask:
1. How MPI distribute the work load?
2. Does the master node divide the work load evenly first, then distribute
to each slave node?
3. Or the master node pass the whole chunk of work load to every slave
node, then the slave node 'take' their own piece of work to process?
4. Can the work load being distributed according to priority (load
balancing)? Or give a bigger portion of work load to the node with higher
processing speed?
Can MPI do the above and how? Where can I learn more on how to use MPI to tune
for best performance for distributed processing and rendering?
Thanks in advance for your feedback!

Re: [Paraview] Losing data when clip multi-block
Eric et al, I recently had a problem where a filter opreated normally when used normally, but when someone put a calculator in front of it, it stopped working. The filter in question instantiated other filters internally. I tracked to the problem down to this. Calculator calls SetActiveScalars(New data) another filter later does a PointData()-PassData(blah) -SetActiveScalars(More New data) And the New data from before was lost. I do not like this SetActiveScalars function because it replaces (not adds) whatever scalar was there before. I cnaged the offending filter (in this case vtkSurfaceVectors) on my copy to do PointData()-PassData(blah) PointData()-AddArray(newData); PointData()-SetActiveScalars(newData-GetName()) or something like that (from memory). I have no idea if this is related to your problem, but I just thought I'd vent my spleen and start a campaigh to remove this SetActiveScalars(...) call as it is just rubbish. (At least it should be modified internally to not remove the old active slalars if they are are about to be wiped) JB Hey Utkarsh, No, I've never seen the clip lose data on one dataset by itself.

[Paraview] Creating ImageData w/Programmable Source
Hello, I'm having trouble creating vtkImageData with the Python Programmable Source. The PolyData Helix example works fine for me, but when I try to create ImageData it seems to build the data structure within Python (i.e. I can print the characteristics of the ImageData and it looks fine in the Output Messages), but no data shows in the Information tab or the 3d render view. Here's the simplest case of the things I've tried (after selecting vtkImageData from the combo box): pdo = self.GetImageDataOutput() pdo.SetDimensions(10,10,10) pdo.SetOrigin(0,0,0) pdo.SetSpacing(1,1,1) print pdo I can add scalars to it, or create a new vtkImageData and then shallow or deep copy that over to the output, and those things look like they're working fine at the print statement, but they don't seem to help get the data to really show up in the pipeline. I hope someone can just point out something I'm forgetting to do...

You can choose the slice axis and offset from the Display Tab. On Thu, Feb 5, 2009 at 3:13 PM, christina.gue...@voila.fr wrote: Hi, first of all, thanks for your answer. For my MHA file, this is exactly the procedure used to open this file: - open the MHA file and choose the meta file format - click on apply button then a white box appears - click on contour and apply buttons and a volume appears as shown in the attached file. The volume is not clear and I don't see the image normally. I would like to know are there parameters for adjusting or any thing else to see the volume and all slices of this volume. Note that I used default parameters and the version that I have downloaded is paraview-3.4.0-win32-x86. Thanks for your time.

If you do see a white box after loading the data than you have a few options: I believe the default ParaView shows you a button along the top of the screen to contour the data. It also shows a button to change the representation of the data from outline to volume. -- David E DeMarle Kitware, Inc.
