Hi, I ma getting stitching artifacts in screenshots larger than my
display (both 3.6.1 and recent CVS on linux). I have 'use
offscreen' enabled in the settings, but get an error message it is being
disabled because of a detected empty screen.
Does anyone else have similar problems?
Hi!
I have opened a figure in Paraview, just defined by surfaces connected
together. Let’s say a cube with six surfaces. In the xml file the velocity is
defined as PointDataScalars and now I want to create stream traces in the
figure. But when I did that with Filters – Alfabetical – Stream
Dear Kitware experts and users, :)
I'm still fighting with my live data reader and my deadline is
approaching :(
In my vtkMultiBlockDataSetAlgorithm derived reader
I implement
RequestInformation()
RequestData()
and
RequestUpdateExtent()
and call Modfied() and Update() from a thread.
Sofar all
If you really have a simple cube, ie just 8 points conected together, it is
possible that stream tracing be impossible because data are too sparse and the
streamline are not long enough to be considered as valid. I would suggest
trying with a little bit more complex dataset.

Looks OK to me. I tested at 1920x1024, on screen and off screen, and
7680x4096, off screen. I was writing png's, using 3.6.1. No stitching, no
error message, no disabled off screen rendering.

Hi Fabian,
I am not sure what you mean by a thread (a client side code?),
but perhaps you can simply write
pqApplicationCore::instance()-render();

Is this a surface or a volume that you are creating streamlines for?
If it is a surface you probably want to use streamtracer with a
custom source and use the surface as the source (either use subdivide
or quadric clustering to increase/reduce the number of streamlines).
I have written some
I also tested on another PC, with an NVIDIA gfx card and it is OK there.
So the culprit might be my integrated intel gfx chip in my thinkpad x60.
Still, I expected off-screen rendering to be independent from hardware,
not so?

Dear last resource :)
My last idea to make my live data reader work is to use animation.
Independed on what time value is requested I give back the current data.
I'll need a repeated loop for that - but once the time values are read,
they are cached and not requested again from my reader.
How
The stream tracer filter follows vector fields in 3D space. Tracing flow on
surfaces is problematic because if a position is off the surface, then the
stream tracer will not follow it.
The default stream tracer seed points is a cloud of random points centered
around some location. Because
You could try using lookmarks, which are design to save a portion of the state
and then apply that to different input data. Lookmarks are created by clicking
on the lookmark icon in that little bar above the view.
That said, although lookmarks are nice when they work, they tend to be quite
Does this happen only with Mesa? That looks like volume rendering,
does it happen with geometry rendering?

Hi,
I want to modify a vtkInformation object (specifically one within a
vtkInformation vector) to point to a new data set.
The use case is I have a derived class for which, in its RequestData
method, I want to do some preprocessing on the input, then send the
preprocessed input to the superclass
I only tried mesa because no graphics hardware are present on that
system. The system is off line today from maintenance, I can see if it
happens with geometry too when it's back on line.

In my case no volume rendering is involved, just a blend of surface
meshes and some wireframes with varying opacities.

Hmmm. Can you try turning off all wireframes?

I followed all the instructions for compiling, installing ParaView. It
seemed to compile without error (64-bit Linux), but when I typed make
install, I got this error near the end:
[ 88%] Built target QtTesting
[ 89%] Built target pqWidgets
[ 89%] Built target pqWidgetsTest

You may also have to call servermanager.Disconnect() before calling
servermanager.ReverseConnect(). This is because paraview.simple
creates a builtin connection by default.

Which version of ParaView is this?

I am not sure why it doesn't work but what you are doing is not safe
and is bad practice. The inputVector belongs to the input of this
filter and you should not modify it (other than passing a request
during RequestUpdateExtent). Isn't there another way you can do this?
Maybe having a data member
