[Paraview] stitching artifacts in screenshots

2009-10-13 Thread Dominik Szczerba
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?

[Paraview] Stream Tracer, Save Layout

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

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. From:

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. Alan -Original Message- From: paraview-boun...@paraview.org

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? Dominik Scott, W Alan wrote: Looks OK to me. I tested at

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

2009-10-13 Thread Moreland, Kenneth
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

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
