J. Cooley's 3-D waterfall display

GNU Radio
1

All,

Mr. Cooley wrote this code sometime early last year, and unfortunately
something in the gnuradio or wxgui code has changed, and this code is no
longer operable.

The error I got in trying to run it with gnuradio 2.8 is:

gnuradio_swig_python.py expects a
std::vector<float,std::allocator>

I had an email exchange with Mr. Cooley, and he would like to fix his
code,
so any effort would be appreciated in that. And, as he said in our
exchange,

“Now that I think about it, the waterfall Python OpenGL code that I did
was
based largely upon the similar wxgui-based fft. So, following the format
of
the wxgui versions may help lead you to the right functional calls, and
get
the right calls on the GnuRadio side.”

Would someone please look at this? Furthermore, I imagine that many Gnu
Radio users would like to be able to perform 3-dimensional FFT displays.

Greetings, all.

OK, I have fixed it, so it runs now with latest code from svn. The fft
block changed since I wrote that code, a long time back. It now expects
a window as a third arg. See the gr_wxgui fft code for a model on how to
structure the flow graph.

Hey, been away for a while… Kudos to all for the many many new things
I see in there! Very cool.
