<_whitenotifier-3> [scopehal-apps] azonenberg 7b2df76 - Minor tweaks to rendering hints in WaveformArea
<_whitenotifier-3> [scopehal-apps] azonenberg f66d6f5 - Rearranged rendering to fix some glitches at high zoom levels

<_whitenotifier-3> [scopehal-apps] azonenberg 376f37b - Now use new rendering architecture for FFT traces
<azonenberg> So, the new rendering fixes some artifacts but involves a fix-up pass after completion of rendering. Which breaks the parallelism i'll need to do tesselation in a shader
<azonenberg> But i should be able to fix that later
<azonenberg> At least for now things look nicer

<_whitenotifier-3> [scopehal-apps] azonenberg d6a4a2f - PrepareGeometry() now keeps track of dirty flag and only re-tesselates if new waveform data is ready or LOD has changed. Fixed unnecessary re-renders of unchanged scenery. Fixes #46.
<_whitenotifier-3> [scopehal-apps] azonenberg closed issue #46: Persistence doesn't clear when horizontally panning a trace - https://git.io/JvY3U
<azonenberg> So it turns out i had a bug where re-rendering was triggered even if there was no new waveform data
<azonenberg> That, combined with re-tesselating and pushing geometry to the GPU every frame even if nothing had changed, wasted a lot of time
<azonenberg> 10M point captures on my workstation are still a little jerky feeling (moving line tesselation to a compute shader should improve update times by close to an OOM) but no longer 5+ seconds of lag every time you interact with the UI
<azonenberg> Zooming in and out is slow, because tesselation is re-done when LOD changes
<azonenberg> So that should also improve greatly when i put that in a shader
<azonenberg> I think at some point i'm going to want to move digital protocol overlay rendering to GL too. Now that i'm not re-tesselating the analog traces constantly i'm spending a lot more time in software rendering proportionally
<azonenberg> Latest profiling from a test with a lot of protocol decodes showed 77% of total render time in Cairo overlays
