I’ve managed to get the streamline representation working and it looks pretty great. However, there seems to be some disparity between the streamline representation and the actual streamlines themselves.
Also could anyone weigh in on the following video?
was it just purely captured with a screencapture device or is there a better way to export this??
StreamTracer and StreamlineRepresentation are two different algorithms, resulting to different results.
To export the StreamlineRepresentation output, one must use a screencapture software indeed.
Will there be a way to export StreamlineRepresentation output in the future?
I’ve obtain the StreamlineRepresentaion output in Paraview 5.9.
- Open View > “Animation View”.
- Turn off “TimeKeeper1 - Time”
- Mode > Real Time
- Big Duration 10000
- File > Save Animation > png export
- Using ffmpeg like:
ffmpeg -r 30 -i stream%04d.png -c:v mpeg4 -vcodec libx264 -pix_fmt yuv420p stream.mp4
My step could have needless step.
Hi your results are very cool, I have a question,
how did you do to load the picture of the city in the backgroud,
I’m looking for something similar. Can you help me?
I´m new ParaView user.
Thank you for your answer is very interesting I’ll, try it; other alternative I found this weekend is exporting the CFD’s results in x3d format and then using blender to combine the results with CAD files given a lot of possibilities. Thank you again for you reply.
For reference, it has been impossible to export StreamlineRepresentation and volume rendered output to x3d file. I’m also using Blender to make final vtk as background in Paraview. But I think Blender has many limitations for rendering CFD results (e.g. volume, moving streamline).
This does not appear to work anymore in 5.10.0. The streamlines are there, but not animated. I tried both Real Time and Sequence.
To be more explicit:
When I attempt to Save Animation of the animated StreamLineRepresentation as described by @Gwang-Jin_Lee, I only get a static image in 5.10.0. I get animations in 5.9.0, though they’re not smooth.
I’m running on a Windows client, which may be relevant.
Provide steps to reproduce. It is working great here (on linux)
I get animations in 5.9.0, though they’re not smooth.
Increase the FPS.
I increased the sequence length from 1e4 to 1e5. I guess that did it.
