Re: [Discuss-gnuradio] Waterfall spectrum display

[James Cooley]

Quite apart from the standard wx GUIs, I've been playing a bit with OpenGL.

This one is the first of two open GL displays I've been toying with:

http://web.media.mit.edu/~jcooley/gr_experiments/experiments/fft_3d_time/gr_3d_fft_time.htm

It's a bit like a combined waterfall and standard fft display and 
performance is surprisingly good! There's no legend and the scale 
markers mean nothing at this point, but at least it looks cool ;) Kind 
of an fft land.
