GPU accelerated rendering of protocol decode event bubbles

Open azonenberg opened this issue 5 years ago • 1 comments

Right now any "complex" type waveform output is rendered in software with Cairo, which gets slow for realtime streaming or fast panning/zooming.

In ngscopeclient, we build the decode bubbles every frame in immediate mode, then submit a batch to the GPU.

Better, but still not as fast as it should be (vs a fully shader based retained mode design). More work needed.
