Re: [Paraview] Creating Plugins
Reproduced the problem on OS X 10.5.6 with latest Xcode tools and
ParaView from CVS (probably pulled yesterday).
Removing the space between '//' and 'ETX' resolves the hang.
Tried to work through the code but didn't get very far. At least it is
reproducible.

Hi
I appended a plugin which makes the wrapper hang here.
Please note - I ripped tons of code out the filter which leaves it
in an uncompilable state - but that's not the point. It makes the
wrapper hang and that's it

Hi Benjamin,
I can't reproduce this. Can you provide an example plugin that

Hi
I think found the problem.
When I have:
//BTX
something
// ETX
(note the space between the comment and the ETX)
This has caused the hang here

Benjamin,
I don't think any of the developers are aware of bug that causes
the VTK wrapping parser to hang. Could you send us a piece of
code that demonstrates the problem?

I just renamed the baseclass now (It is not inside a library so
that's
no issue) and the parser seems to accept this. Adding //btx //etx
works
but that's not really an ideal solution. IMHO, the grammar of the
parser
should be changed for such things to be possible.
I'm using the svn version of paraview and the parser seems to hang
but
it doesn't report an error. I assume that's a bug which will be
fixed
pretty soon
Thanks

Hi
I'm trying to create a paraview plugin out of a filter I'm

writing for my own viewer. I'm hitting several roadblocks with the
parser:
*** SYNTAX ERROR found in parsing the header blablabla
I currently found the following issues:
class Something; // Not allowed because it does not start with the
vtk Prefix
class vtkMyFilter: public vtkSomeFilterClass, public
MyBaseClass //
Probably same as above, but I'm not sure
{
void SomeFunction(Eigen::Vector3f arg); // I assume I can't take
arguments that are not primitive types or don't have the vtk

}
Is there anything I can do about these issues?

Re: [Paraview] hyperstreamline visualization
Hi Pierre, The reason the filter does not show up is that it has the same name as an existing one.

So, I wanted first pointing out a possible interesting feature: having two buttons when dealing with plug-ins: - select having the functionality of the current load one: selection of an XML file - a load or apply button to confirm the selection of the XML file and maybe achieving some controls: - is the file empty? - does it start with the ServerManagerConfiguration tag? - and so on... (well, the standard controls that allow the use of an XML file I guess...) Then, here is my main question: I'm not sure at all the loading worked correctly: Where am I supposed to find the loaded filter to apply it on an example? I went in the Filter tab and I couldn't see it anywhere... (see attached picture) I am of course not interest in the vtkCellDerivatives lcass: I know that it is availabe with the filter Compute Derivatives. It is just a test. Could you point me out where is the mistake? I have to say that I didn't use any GUI XML, as it is said being optional in the page: http://www.paraview.org/Wiki/Plugin_HowTo#Enabling_a_filter_in_VTK In addition, just for information: where does the name displayed in the Filter tab comes from? Is it the value of the SourceProxy tag \name attribute? In this case, are we forced to prepend vtk from the vtk class name to obtain it? It would indeed mean that we cannot have blank in the name. Concerning the wiki, I have also few questions. - First, once I have this working for HyperStreamLine, I guess that it may interest other users. Wouldn't it be interesting to have a section in the wiki where users could drop validated server manager configuration files for VTK classes that could then be downloaded by others? - Finally, I found the old page: http://www.paraview.org/Wiki/ExtendingParaView#Enable_Existing_VTK_Class more detailed than the new one. Shouldn't they be merged? Tell me if I can help on this topic. Cheers, Pierre 2008/12/18 Pierre JUILLARD pierre.juill...@gmail.com Hi all! I had a look on the wiki, and indeed, one can find information at the page you pointed me: http://www.paraview.org/Wiki/Plugin_HowTo#Enabling_a_filter_in_VTK but also at that one: http://www.paraview.org/Wiki/ExtendingParaView#Enable_Existing_VTK_Class Very interesting information are given, however, I think I am missing something. Just to try out, I copy/past the given Server Manager Configuration file in a xml, naming it vtkCellDerivatives.xml. I loaded it as it is indicated (using the Plugins Manager), as shown on the following picture. (By the way, I'm surprised that there is no confirmation of the correct loading.

Different solutions may exist: 1). For instance, evaluate the principal components (vectors) from stress tensor and use the 'stream tracer' filter to visualize each principal component individually. However, in the 'Calculator' filter, I see neither 'extract principal component' function, nor the possibility to interact with tensor at all: only the access to scalars and vectors is allowed. Could you confirm me this? 2). Another actually much more interesting way would be to use the Hyperstreamline method available in the VTK library (http://www.vtk.org/doc/release/5.2/html/a00565.html). Nonetheless, I don't see the equivalent filter in ParaView. Is there a way to 'activate' it simply in ParaView? Or should an external filter be developped (based on the existing VTK class)?

Re: [Paraview] Plot on a Contour surface
