AW: 3D plots or image display in GR

[Dobler, Anton]

Hi Marcin,

Take a look at this: https://github.com/antondobler/gr-SurfaceInspector​

I recognized that there is still a problem concerning memory. I have not found that error until now, however if you can make any improvements for that block let me know!

Should be kind of a starting point!

Thank You for the help and suggestions.

Anton Dobler is your port of vis3d to 3.8 available somewhere on Github? I tried to look for your fork but didn't find it. (The only thing having the modification in regard to 3d plot was:
https://github.com/chrisruk/gr-inspector , but it has some problems after install like: AttributeError: module 'inspector' has no attribute 'vis3d_vf', even after sudo ldconfig and so on)

Your port/implementation would be very useful to start from with 3D in GR.

Martin Braun, gr-specest will save me a lot of time so that I can focus on understanding what is going on inside.

Kind regards,

Marcin Wachowiak

Marcin,

gr-specest (https://github.com/kit-cel/gr-specest/) has some cyclostationary code, as well as some matplotlib-based plotting thereof. The code was written in the Py2k era and might be out-of-date. But it might be an inspiration!

Hello,

I would like to experiment with some cyclostationary signal detection in GNU Radio.

In order to visualize the results, I need some kind of 3D plot or 2D image plot (to visualize matrix values). Having searched for similar topics on the internet and mailing lists I decided to ask here.

What could be the best approach to obtain such plots in GR? Should I try to introduce a new Qt block or use an embedded python block with matplotlib (create a sequence of plots, animation)? I can also do simple postprocessing after collecting the data but live visualization or one with tolerable latency would be most desirable. Maybe I can utilize some of the existing blocks like constellation sink and change the colours of points accordingly to values in the matrix?

Please let me know your thoughts.

Kind regards,
