Re: [Paraview] Save Animation option in ParaView 5.4.0 vs 5.3.0

[David E DeMarle]

Hey Mark,

Looks like we took that out as part of the revamp described here:
https://gitlab.kitware.com/paraview/paraview/issues/15917

Specifically this merge request took out the "No. Frames" entry.
https://gitlab.kitware.com/paraview/paraview/merge_requests/896
because, at least at that time, apparently the control didn't do anything
at all.

A 1 commit merge request that restores the widget and hooks it up to do
what it apparently did at one time is
here. https://gitlab.kitware.com/paraview/paraview/merge_requests/2197

Re: [Paraview] OSPRay ignores transparency

[David E DeMarle]

It is a known bug in VTK's interface to OSPRay such that opacity is ignored
in some cases dependent on some of the other color controls.

Re: [Paraview] Segfault with 'Hover Cells' over 3d glyphs

[David E DeMarle]

The output warnings you are seeing are unrelated and fixed in master.

Can reproduce the bug with 5.4.1 binary on linux.

Re: [Paraview] Writing XML VTK Binary files from C++

[David E DeMarle]

Another approach is to use VTK itself to write the files.

Since VTK 6 it is straightforward to configure a VTK build consisting
of only the IO/ParallelXML module and its required dependencies. To do
so, in cmake, turn of testing, all groups and turn on
Module_vtkIOParallelXML, and you should be set.

Re: [Paraview] XDMF file with multiple temporal collections

[David E DeMarle]

Try dropping your standalone external geometry and topology and just place
them in the first timestep's grid. It might make the reader happier.
Like so...

http://www.w3.org/2001/XInclude; Version="3.3">
  

  


  0 0 0 1 0 0 0 1 0 1 1 0 0 0 1 1 0 1 0 1 1 1 1 1


  9 0 1 3 2 4 5 7 6


  0 0 0 0 0 0 0 0

...

Re: [Paraview] Error reading timeseries with spatial grid collection with XDMF

[David E DeMarle]

It might be that the reader doesn't like or want that both of your times
are 0.0.
...

...

...
but your third case doesn't fit that hypothesis.

Otherwise your file looks ok at first glance. I'ld have to debug the reader
on your data to figure out what is going wrong.

Re: [Paraview] SWKey: File extension for PV Readers?

[David E DeMarle]

Not yet.

You could add one by editing the appropriate "ReaderFactory extensions"...
line of ParaviewCore/ServerManager/SMApplication/Resource/proxies_xdmf3.xml
in your builds.

Re: [Paraview] paraview osmesa render on supercomputer nodes

[David E DeMarle]

---

This syntax isn't clear to me:
> srun -n 24 pvserver -sp=15801 --mesa --use-offscreen-rendering
--disable-xdisplay-test
---ssh -N -f -L15801:localhost:15801 though internal connection-->
Where are you trying to run ssh on to open up this second (between login
and compute) tunnel?

---
ERROR: In /HOME/pp569/soft/ParaView-v5.4.1/VTK/Common/System/vtkSocket.cxx,
line 206
vtkServerSocket (0x20e9c20): Socket error in call to bind. Address already
in use.

Indicates that pvserver is trying to grab a socket that some other process
owns. You might be competing with one of your other pvserver processes
(from an earlier run or perhaps a misconfigured non-mpi pvserver task
running on the same node from this srun invocation) or possibly your ssh
tunnel process.

---

Forward connections from desktop to login to compute are harder to setup in
most cases because in general you don't know what compute node (and
sometimes login node) you will get.

---

I recommend using something simple like netcat to send and receive messages
across each tunnel. If you can type on one side and see the text on the
other, then paraview should be able to use the connection.

---

Please let us know how it goes. We would love to see ParaView running on
Tianhe-2!

[Paraview] About the SC17.5.5.preview binaries...

[David E DeMarle]

Hey folks,

As Utkarsh pointed out on Oct 23'rd "ParaView Release Roadmap", we decided
to push the 5.5 ParaView release from just before IEEE SC17 out to the
Spring of 2018.
Still there are a lot of good things already in master that we want to show
off at SC that we'd like to draw your attention to. So we decided to put
these current master binaries up on the download page as a technology
preview of what's coming in 5.5.

* The OSPRay path tracing capability and the accompanying Light Inspector
panel are pretty nice if I do say so myself.
* The separate color maps option that makes it easy to have multiple color
lookup tables for the same named array (on different representations of
views for example) is quite handy in certain situations and frequently
requested by users.
* We moved Tools->Python Shell to View->Python Shell and made it a dockable
widget.
* The nvpipe image compressor option does a great job at speeding up server
to client image delivery from nvpipe enabled servers.
* The Cell Size filter is another very handy little addition as are the new
Gradient Filter options.
* The revamped zoom to box camera interaction is much more predictable than
before.

There is a lot more that I am omitting for brevity but the point is that
there are a lot of good things to look forward to when 5.5 comes out in the
Spring. So please do give the 5.5 technology preview binaries a whirl and
let us know what you think of them via the mailing list and or issue
tracker. That will help a lot as we finish up even more features and work
to make the current ones even better.

thanks,

Re: [Paraview] OSPRay, scaled spheres

[David E DeMarle]

Looks like:

1) I was wrong, you don't need to scale and bias the input array into 0..1.
The transfer function editor widget's piecewise range controls let you
specify what the input domain extent.

2) You are correct that there isn't currently a way to get the radii to be
> 1.0 when applying the transfer function. Without the transfer function,
the point size control sets the radii for all points. With it the transfer
function's output (which is defined to be 0..1) controls the radii of each
point. Please file a bug report.

Notes: With Point Gaussian representation there is an extra "point gaussian
radius" control that gets factored in. We could do that with ospray, or
factor in the existing point size, or possible extend the transfer function
editor widget to change the range extent to something other than 0..1.

Re: [Paraview] OSPRay, scaled spheres

[David E DeMarle]

That control is only available if the representation type is surface, this
could explain why you don't see it on the ProgrammableSource.

In the glyph filter, use 2D glyph, VERTEX.

Re: [Paraview] OSPRay, scaled spheres

[David E DeMarle]

To change the size based on values:
check "OSPRay Use Scale Array" on "Display" section or "Properties" Tab
Choose the array name you want to scale by with "OSPRay Scale Array"
pulldown.
Define your value to radius transfer function via the "OSPRay Scale
Function" popup editor.

Note 1: the transfer function is defined to map between 0.0 and 1.0 and
clamp outside of that range. Use a calculator to scale and bias into that
range. If you don't like having to do this, file a feature request to
remind the developers to implement it one of these days such that min is
defined to be array min and max.

Note 2:Cutter will not cut through the implicit spheres.

Note 3: Point Gaussian representation's Use Scalar Array, Guassian Scale
Array and Scale Transfer Function (which I riffed off of) are similar. I'm
not sure about scale and bias and cut with this GL shader based side.

Re: [Paraview] multiple scalar fields

[David E DeMarle]

Give each array a name (vtkDataArray::SetName()) and use AddArray
(vtkFieldData:AddArray()) instead of using the atttibutes based API
(vtkDataSetAttributes::Set{Scalars/Tensors/Vectors})

ParaView uses named array access almost exclusively anyway.

Re: [Paraview] Creating clips for multiple data sets

[David E DeMarle]

Howdy,

Two ideas for you to try. 1) group the data into a multiblock and then clip
the merged result with one clip filter. 2) under the tools menu create
property links between the many clip filters so that whenever one changes
the rest do too.

Re: [Paraview] XDMF Version 2 and 3 Differences

[David E DeMarle]

Hi Mike.

You mean select the XDMF "Reader", not "Writer" when you open the file
correct?

In theory XDMF3 should read almost anything XDMF2 could. The main practical
differences in my recollection are:

+ xdmf3 doesn't leak memory and is faster and less of a memory hog,
especially with time varying data, in my experience.
+ xdmf3's field data arrays work better and in particular support arbitrary
width arrays
+ Thanks to Michal Habera's Google Summer of Code project xdmf3 master (in
nightly binaries and will appear in PV 5.5) has support for "other"
centered (more than 1 per cell) data in support of FEniCS higher order
cells.
+ xdmf3 has a much better suite of tests and contribution path than xdmf2
ever did

= xdmf3 had a boost dependency up until about a week ago (will appear in PV
5.5).

- xdmf3 tends to complain on files that use default/implied values in the
xml entries.
- xdmf3 doesn't automatically parallelize structured datasets when read in
parallel
- xdmf3 doesn't support strides for structured datasets
- xdfm3 doesn't support "hyperslab, list or range" temporal specifications
- xdmf3 lacks support for function specifications
- xdmf3's notion of subset is slightly different than xdmf2 (2's were
relative to cell, 3's are relative to face/edge or something to that effect)

If you can share one of your files I'll take a look.

thanks

Re: [Paraview] Windows MPI capable Paraview binary install package question

[David E DeMarle]

Hey Giovanni,

We publish two windows binaries for ParaView. The one without mpi in the
name doesn't need anything special to run. The other one depends on
microsofts mpi, which do not provide, but is available from microsoft for
free and is easy to install if you have the need.

Your suggested path of deploying the non-mpi one sounds best to me.

cheers!

Re: [Paraview] [vtkusers] Do you have data that I might show off OSPRay rendering with?

[David E DeMarle]

Thanks for the references Bill.

My backup plan is to find a suitably licensed model of a car from one of
the sites like free3d, but I'm hoping for something more "real world" from
someone's day to day work out there.

[Paraview] Do you have data that I might show off OSPRay rendering with?

[David E DeMarle]

Hi lists,

We've been working lately to expose OSPRay's path traced lights and
materials inside VTK and ParaView. I'd like to make some snazzy
photorealistic images and movies now and post them on the website, at
conferences  and in press releases.

Unsurprisingly the images I can make out of vtkSphereSource and the like,
are not all that compelling. That's why I'm reaching out to see if anyone
has some great looking, real world, data that I might work with.

I am thinking something like a car with lots of glass and metal and rubber
would be ideal - especially if the data also had some interesting attribute
data on it that I could colormap at the same time. I'm more than happy to
attribute the data however you like.

Feel free to contact me off-list if you like.

thanks

Re: [Paraview] OSPRay Surface Opacity

[David E DeMarle]

A couple of observations:

1) for surface rendering with color mapped array, vtk's OSPRay interface we
does not yet respect transparency (either at the actor level or in the
alpha channel of the colormap). If you use a solid color for the entire
actor (PV GUI color choice is "Solid Color" instead of one of the arrays in
the data) then we do respect opacity.

2) we turn on aoTransparencyEnabled whenever there are volumes in the scene
https://gitlab.kitware.com/vtk/vtk/blob/master/Rendering/OSPRay/vtkOSPRayRendererNode.cxx#L870
If your scene doesn't have volumes in it, then you'll need to compile from
source and enable that generally (remove the if conditon).

Feel free to submit patches or bug reports to for either of those things to
help us remember to improve them.

[David E DeMarle]

Please reply-all to keep the mailing list on the thread so everyone can
contribute to the discussion and benefit from it.

To make a multiblock from xdmf, enclose your grid inside of an
xdmfgridcollection like so:

Re: [Paraview] XDMF Reader

[David E DeMarle]

Put the co-rect-mesh (image data) inside a grid collection (multiblock).

Paraview's pipeline doesn't deal well with image data that changes
dimensions over time. This is not limited to xdmf. When inside a
multiblock, a different pipeline layer takes over and it works out.

Re: [Paraview] [EXTERNAL] Is anyone using the Extra Headlight in ParaView?

[David E DeMarle]

The only reason to "get rid of it" is because something new is coming that
is a superset of its functionality. From a user perspective it would be
instead of "turn on the extra headlight" it would be "add light and select
headlight as its type". Afterward they would behave exactly the same.

[Paraview] Is anyone using the Extra Headlight in ParaView?

[David E DeMarle]

By default, Paraview illuminates the scene with a vtkLightKit
<http://www.vtk.org/doc/release/5.0/html/a01682.html>. You can however add
an extra headlight. I am about to add a more general capability which lets
you add any number and any kind of light, including the headlight. When I
do that, the semi-hardcoded extra headlight becomes redundant. I would like
to remove it to streamline both the code and the UI.

Are there any objections to me doing that?

Re: [Paraview] How to properly visualize data in Paraview using HDF5?

[David E DeMarle]

cc'ing the list back in

xdmf has join for this purpose, but I typically use python filter in
paraview to join the scalars together into a vector instead. That route is
more widely traveled.

Re: [Paraview] [Camera Control] - Clipping Range

Try LockBounds.

For example:

view.MaxClipBounds = [x0,x1,y0,y1,z0,z1]
view.LockBounds = 1

Re: [Paraview] superbuild: configure: error swr requires C++14 support

[David E DeMarle]

Hi Nabil,

That was a regression that snuck in just before the 5.4.0 tag. Apologies.

One commit beyond the tag fixes it by patching mesa 17.1.1 to remove the
c++14 dependency.
https://gitlab.kitware.com/paraview/paraview-superbuild/commit/aa8a66b270fb481e39b9919f9ea68017a3a1543b

The patch is also now in mesa 17.1.3. ParaView 5.4.1 will address this by
bumping mesa and removing the patch.

99% certain that you have to build from source.
The paraview binaries from Kitware do not have it.

Re: [Paraview] [EXTERNAL] FW: paraview error.

[David E DeMarle]

That is a Qt thing and not strongly related to ParaView. I found out about
on a non ParaView project (Cinema's qt viewer) a while ago.

It basically tells Qt apps not to rely on the availability of shared memory
in X something or other.

I find Programmable Filter script string(s) that simply execfile(...) or

Re: [Paraview] Simple XDMF example

[David E DeMarle]

Try something like this:

http://www.w3.org/2001/XInclude; Version="3.0">
  

  
0 0 0
1 1 1
  
  
  
small_ds.hdf5:/myelin
  

  


If that doesn't work sent me the h5 offlist and I'll fix the above

Emphatically yes, with the caveat that the data has to be large, and the
format must be one that we have a parallel aware reader for. If the data is
small or every node has to read the same portions then performance will be
bad in parallel regardless and the PFS can make it worse.

Re: [Paraview] 3D Data Visualisation

[David E DeMarle]

I recommend Filters->PointVolumeInterpolator to make a mesh out of these
isolated points so that you have something to isocontour within.

On also recommend Enable OSPRay or to change Representation to Point
Gaussian to give these points some extent an local normals to make the
lighting look better on the point cloud.

Re: [Paraview] xdmf2 vs xdmf3 file type

[David E DeMarle]

We're planning to deprecate and remove xdmf2 this summer. So this will be
less of an issue in a release or two.
That said feel free to submit a merge request and I'll merge it.

Re: [Paraview] pvpython vtkMPIController usage? rank is always 0

[David E DeMarle]

Run with --symmetric.

Without it, only root node reads the script and it tells the rest of the
nodes what to do via paraview's proxy mechanisms (which take effect only
for vtkSMProxy and subclasses).
With it, every node reads and executes the script and all nodes do their
own parts behind the proxies.

Re: [Paraview] pvpython vtkMPIController usage? rank is always 0

[David E DeMarle]

Try your script within pvbatch.

pvpython is analogous to the Qt client application, it (usually) is not
part of an MPI execution environment. Either one can connect to an MPI
parallel pvserver.
pvbatch is a python interface that is meant to be run on the server. It is
directly connected to the pvserver.

Re: [Paraview] Integration points visualization

[David E DeMarle]

Please reply all to keep the mailing list on the discussion so all can
participate in and benefit from the discussion.

Question 1: Why delete columns? All of the columns can be point aligned
attributes.
Question 2: Are you sure you want a Structured Grid?

Table To Points will give you a simple point cloud. Table to Structured
Grid has the extra requirement that the points in the text file are ordered
regularly to make up a toplogical grid. If that is the case, then in
addition to designating the X, Y and Z columns, you also have to specify
the whole extent so that the filter knows how many cells there are in the
i, j and k dimensions.

Re: [Paraview] Integration points visualization

Try Table to Points filter and use the "X Column" "Y Column" and "Z Column"
properties to match up specific columns to the X, Y and Z point coordinates.

Re: [Paraview] Change a property of multiple data objects simultaneously?

[David E DeMarle]

I suggest using the group filter to make a multi block and then changing
the display properties of the collection there.

Alternatively there is Tool->Manage Links which should let you set up links
among the properties to control the whole set simultaneously.

Unsure what you mean by this projection. Depending on what the layout it
might be hard or easy to assign U/V coordinates that pick the right pixel
for each location on the surface of the sphere.

There is a texture map to sphere filter which creates U/V coordinates on a
data set. Once the data has U/V coordinates, you can load an ally a texture
from the Display section of the Properties panel.

Re: [Paraview] xdmf2 vs xdmf3 file type

[David E DeMarle]

They both claim ".xmf" and ".xdmf" via the ReaderFactor extensions line you
will find in readers.xml and proxies_xdmf3.xml. If one had something like
xmf2 and the other xmf3 it would do what you are asking for. You could do
that if you build from source for example.

If not you should be able to force something like that by making a dummy
reader xml only plugin just to get the file extension association. See
http://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Adding_a_Reader for
hints.

Re: [Paraview] ParaView v5.3: Generating textures from scalars and lookup table

[David E DeMarle]

Hi Nenand,

You might try vtkMapper::GetColorMapColors/ColorCoordinates/ColorTextureMap.
I'm using this in the OSPRay renderer for example.

Out of curiosity is this for the p2f3d exporter plugin?

then set paraview_SOURCE_DIR to some directory where you've got your
version of the paraview source tree.

Re: [Paraview] [Non-DoD Source] Re: Volume rendering with OSPRay Renderer not working with ParaView 5.3.0-RC3 (UNCLASSIFIED)

[David E DeMarle]

Just remembering now that OSPRay (currently) only has volume rendering
implemented for image data.

Please try the resample to image filter and that should look OK in OSPRay.

Also - please file an issue on gitlab to remind me to make the UI warn
whenever ParaView hands OSPRay something incompatible rather than just
rendering nothing.

Re: [Paraview] [Non-DoD Source] Re: Volume rendering with OSPRay Renderer not working with ParaView 5.3.0-RC3 (UNCLASSIFIED)

[David E DeMarle]

Thanks Joe.

I'll take a look at the silo data tomorrow and see what I can find.

For the large ugrid data, if you can tell me the size and number/type of
arrays, that would help diagnose and/or allow me to make something to
replicate the behavior.

Another thing that will help isolate is if you can try with 5.1 and or 5.2
and tell me if the behavior changed. If so I should be able to pinpoint
what change broke it.

Re: [Paraview] XDMF Multiblock limit on number of blocks shown in Hierarchy

[David E DeMarle]

It is a max constant in defined in the XDMF readers.

from Xdmf3SILBuilder.cxx for example:

// As soon as num-grids (sub-grids and all) grows beyond this number, we
assume
// that the grids are too numerous for the user to select individually and
// hence only the top-level grids are made accessible.
#define MAX_COLLECTABLE_NUMBER_OF_GRIDS 1000

Re: [Paraview] pvpython pass string to Script (Programmable Source)

[David E DeMarle]

Use the hidden property called Parameters on the Python Filter/Source to
pass in information.

>>> prosrc = ProgrammableSource()

>>> prosrc.Script = ("""

... try:

...   instring

... except NameError:

...   instring = "GOODBYE"

... print instring

... """)

>>> prop = prosrc.GetProperty("Parameters")

>>> prop.SetElement(0, "instring")

1

>>> prop.SetElement(1, "'HELLO'")

1

>>> prosrc.UpdateProperty("Parameters")

True

>>> prosrc.UpdatePipeline()

HELLO

Re: [Paraview] OSPray rendering: ERROR: VolumeMapper's Input has no scalar array!

[David E DeMarle]

 That's a bug in either the OSPRay mapper or the ResampleToImage filter,
depending on your point of view. To workaround, put a python programmable
filter into the pipeline to annotate the array as being the "Active
Scalars".

In it, choose:
Output Data Set Type = "Same as Input" //the default
check "Copy Arrays" //not the default
for script use :self.GetOutput().GetPointData().SetActiveScalars("RTData")

Re: [Paraview] ParaView Catalyst: export point data

[David E DeMarle]

Ah, then you can skip the filter and directly make a vtkUnstructuredGrid
containing only points and VTK_VERTEX cell that index them.

See section 3 of the users guide for details. Somewhere in your adaptor you
will have something like the following:


output = vtk.vtkUnstructuredGrid()
pts = output.GetPoints()
cells = output.GetCells()
for i in particles.len():
  pids = [i]
  pts.InsertNextPoint(next_coordinate)
  cells.InsertNextCell(vtk.VTK_VERTEX, 1, pids)

When you get that working you will want to replace the inserts with direct
memory references to the  possible.

Re: [Paraview] ParaView Catalyst: export point data

[David E DeMarle]

Glyph Filter, type=2D subtype=points will create 1D cells (VTK_POINTS type)
for every point (those that are attached to cells and those that are not
used by any cell). To get only those points that are not used by cells, you
may need the programmable filter.

Re: [Paraview] [EXTERNAL] OSRay and shadows

[David E DeMarle]

Bob,

There is no control for that just yet. Work is in progress to provide the
full complement of light controls. If you are working in builting mode, you
can resort to python as follows.

lights = GetActiveView().GetRenderer().GetLights()
for i in range(0, lights.GetNumberOfItems()):
   lights.GetItemAsObject(i).SetLightTypeToSceneLight()

Note: the light position bug in 5.1 that Alan was referring to had the
effect of making making the light positions fixed (scene lights in vtk
terms). In 5.2 that was corrected and now they are camera relative lights
that move with the viewer as they do with GL rendering.

hope that helps

Re: [Paraview] Newer object always in front in Render View

[David E DeMarle]

That's pretty crazy. You typically have to do some coding to get the
layering effect.

Try running with -dr to disable your preferences and settings. Also, please
share more information about your binary and OS as well as passing along a
state file to see if anyone can reproduce it.

Re: [Paraview] Still Render in PV5.2.0 takes longer time than in PV4.4.0

Is this with OpenGL1 or 2 back end? If you are using Kitware's binaries 4.4
will be OpenGL1 and 5.2 will be OpenGL2. If you built from source or got it
from a distro then it might be otherwise.

Re: [Paraview] Custom Glyph

[David E DeMarle]

Glyph with Custom source filter can do it. Note that it works in CPU/RAM
instead of in a GPU shader so memory can be an issue for all the replicated
geometry.

To use it, manufacture a mesh that appears the way you want it and save it
in a common mesh format. Load that into the pipeline and hide it, select
the object you want to apply glyphs to and apply the Glyph with Custom
Source filter. Choose the shape you read in as the "Glyph Type" input.

some of the time. ;)

If you open it up with the spreadsheet view (so no rendering), you can see
that the cell connectivity array gets nonsense in it - some of the time.
When you then open a renderview and show it, it crashes.

So something about the read in of the connectivity data has an
uninitialized/misaligned word somewhere.

Can confirm that it Alessangro's initial xdmf file fails on windows (crash
is in somewhere in the rendering stack - need a debug build to diagnose
further) but works OK on Linux.

Please submit an issue on the ParaView issue tracker.

Re: [Paraview] How to set properties of custom vtkSMProxies (python)?

[David E DeMarle]

The immediate_update flag that you can set in XML doesn't quite do what you
want and it seems like it may be deprecated soon.

Internally vtkSMProxy::UpdateProperty takes an optional force flag, but I
don't see that exposed anywhere public that won't involve writing some
paraview SM code to use it.

What you might do is add a pure vtkProperty (not vtk*vector property) that
calls some method on your class. Those take no arguments so they always
execute on the server when asked for by the client.

Re: [Paraview] OSPRay rendering issue

[David E DeMarle]

Most likely you are running into this bug:
https://gitlab.kitware.com/paraview/paraview/issues/16919

Try applying the generate surface normals filter and see if you get colors
then. If you can, please send me a screen capture and the data if
permissible to help track it down.

Re: [Paraview] Paraview python script: passing images to PIL (python image library)

[David E DeMarle]

Unless you can rely on PIL being on the system search path yes.

In my case PIL is mostly optional so if you look closely you will see paths
that avoid PIL if not present when Catalyst writes out cinema files.

Re: [Paraview] Paraview python script: passing images to PIL (python image library)

[David E DeMarle]

Look into the cinemaIO directory of ParaView. We move back and forth
between paraview, numpy and PIL often there.

For example:
image = self.view.CaptureWindow(1)
ext = image.GetExtent()
width = ext[1] - ext[0] + 1
height = ext[3] - ext[2] + 1
imagescalars = image.GetPointData().GetScalars()
idata = numpy_support.vtk_to_numpy(imagescalars)
image.UnRegister(None)
imageslice = idata.reshape(height, width, 3)
imageslice = numpy.flipud(imageslice)
pimg = PIL.Image.fromarray(imageslice)

Re: [Paraview] Can't export to vector graphics in ParaView 5.0

[David E DeMarle]

Yes that is known.

SVG output was temporarily lost in the initial transition to OpenGL"2"
rendering back around 5.0.
I think it returned before 5.1.

Note also that if you built 5.0 from source but choose the OpenGL"1"
backend instead of the then newly default OpenGL"2" you would also have it.

Re: [Paraview] Building ParaView v5.1.2 on Linux from source with support for GPU and SWR.

[David E DeMarle]

I recommend the ParaView superbuild. All of the incantations that we use to
setup and build paraview, mesa and the rest of our dependencies are written
down and maintained there.

https://gitlab.kitware.com/paraview/paraview-superbuild

We've used it for our Desktop binaries for years, and more and more often
we use it for our HPC installs as well.

Re: [Paraview] pvbatch hangs when enabling OSPRay

[David E DeMarle]

Ben,

I am not able to reproduce this locally. Can you file an issue to help me
keep track of it on ParaView's new gitlab issue tracker?

Re: [Paraview] Xdmf Reader always asks for version 2 or Version 3

[David E DeMarle]

Sorry not without hacking a bit.

Thoughts about how to go about it:

You can configure a ParaView build to have just one or the other, in which
case the choice goes away.

Change the .xdmf file extension to something like .xdmf2 or .xdmf3 and then
register the extension to just one of the readers.

Extend vtkXdmf*Reader::CanReadFile to check for some version attribute near
the top of the file and return no if the file is meant for the other reader.
