[Paraview] Properties Scroll Slowly with Cursor over Series Parameters

[Joel Kulesza]

Colleagues:

Has anyone else experienced unusably slow vertical scrolling through the
parameters dialog when the mouse is over the Series Parameters (i.e., the
various data series to plot)?  I'm seeing this on a 2017 MacBook Pro
running macOS 10.12.6.

Steps to reproduce:

1. Load a legacy VTK file with ~2 dozen data series (I'm using line chart
data).  The amount doesn't matter, but must be enough to take up a
nontrivial amount of the properties pane.
2. Click the properties "gear" to enable advanced properties (to give more
real estate to scroll through).
3. Position cursor next to "X Axis Parameters" label (a neutral area).
4. Begin to slowly scroll the dialog to reveal lower parts.  This should be
fluid until the cursor, floating above the scrolling content, comes over
the box of variables/swatches/legend names.  For this scrolling, because
I'm on a laptop, I'm using the "two-finger drag" on the touchpad.

Once the cursor is over the Series Parameters scrolling will become almost
impossible.  The only way to overcome this is to move the cursor over the
macOS vertical scroll bar, and scroll here.  This isn't an ideal solution
because this scrollbar is hidden by default.  Another approach is to
swipe/scroll so quickly as to let the inertia carry the cursor over this
trouble region.

This is very likely macOS specific, but it would be be helpful if someone
could confirm.  If confirmed, I'll file an issue in the tracker.

Please contact me with any comments, questions, or concerns.

Thank you,
Joel

Re: [Paraview] "Reload Files" Hotkey Acting on Individual Items --- Expected?

[Joel Kulesza]

Joachim,

Excellent, thank you for that snippet—it worked perfectly.  My thanks also
for correcting my terminology.

Is this something that would merit adding to ParaView's native
functionality (e.g., File -> Reload Files & File -> Reload All Files)?

Best regards,
Joel

[Paraview] "Reload Files" Hotkey Acting on Individual Items --- Expected?

[Joel Kulesza]

Colleagues:

In the File menu I would expect that the "Reload Files (F5)" command would
apply to all items in the pipeline browser rather than the one currently
selected or last acted on.  For individual reloading, I would expect to
need to use the right-click approach to "Reload Files."  However, this does
not seem to be the case.  If I open multiple, independent, data files that
I want to plot together, I must select each one in the pipeline browser and
reload it (either via F5 or right-clicking) to see changes.

Am I correct that the "reload files" hotkey only applies to the currently
selected or last used item (a file or collection of time-series files) in
the pipeline browser?  If so, is there a method to reload all items in the
pipeline browser (ideally avoiding the need to select all the files)?  If
not, can this be added as an enhancement request (e.g., menu item/hotkey
for Reload All Files)?

I'm using ParaView 5.4.1 in OS X 10.11.6.

Please contact me with any comments, questions, or concerns.

Thank you,
Joel

[Paraview] ParaView 5.4.0 Volume Rendering Inquiry

[Joel Kulesza]

Colleagues:

Has anyone else had problems rendering with "Volume" representation with
the as-distributed ParaView 5.4.0 (on OS X 10.11.6)?  When I select that
representation and "Yes" to the box regarding possibly taking a while, I
have only a white/blank Render View.  This is the case regardless of
coloring, colormap, or lighting options. Sometimes if I rotate the view,
I'll see a pseudo-surface representation, but when I stop I return to a
fully white render view.

In 5.4.0, I create the Volume by first Tetrahedraliz'ing my data set and
then selecting Volume representation.  Conversely, if I load the same data
in 5.2.0 and select Volume directly, it plots as I would expect.  If I try
to do the same in 5.3.0, it hangs on the render (status bar at the bottom
gets ~80% of the way and doesn't appear to proceed further).

Note that if I plot the same data in VisIt, it shows a Volume as I would
expect and quickly enough that I don't believe impatience to be my issue
(the data set is relatively small).

Any thoughts are appreciated.

Please contact me with any comments, questions, or concerns.

Thank you,
Joel

Re: [Paraview] Using results from multiple plots/data to get average

[Joel Kulesza]

Jairaj,

My first thought would be to use a Programmable Filter:

https://www.paraview.org/Wiki/Python_calculator_and_programmable_filter#Programmable_Filter

The examples are for PointData, but it also works for CellData.

I hope this helps.  Please contact me with any comments, questions, or
concerns.

Thank you,
Joel

Re: [Paraview] Method to Clip Sources & View Closed Volumes?

[Joel Kulesza]

Cory,

Thanks for the reply.  Indeed, that's what I suspected was the case and
it's all reasonable.  I was just hoping there might be a way to set a
preference (or another mechanism) so that when a user applied "clip" it
would perform the manipulations necessary to "see" the interior as a solid
region.

I tried applying the Deluanay3D filter to my sphere (80 theta & 80 phi
segments) and got a broken triangularization.  For more complicated shapes,
I'm concerned I'll have a similar result.

Perhaps asking my question another way: is there a recommended approach to
converting constructive solid geometry (CSG, which is effectively only
concerned with boundaries) to something that could be viewed in ParaView
with filters like "clip" meaningfully applied to see the interior regions
(because the end-user may be interested in that internal structure).  For
example, if I had several nested spherical shells defined with CSG, I'd
like to clip them and see those shells and not just the surfaces between
them.

Thanks,
Joel
