High fidelity animation in Hise - What are my options?
-
Thanks!
Is it possible (easy
) to create display buffers for external nodes?Else I can use a peak node or similar I guess to get to that step? Trying to be performant and have as few steps of 'translation' as possible with the data to get it into the path format.
-
@griffinboy Like this?
-
@griffinboy yes, use a peak node right after and then plot its data. Set it to an external buffer and use that with a floating tile.
-
You can also use a peak node as a member within your C++ class and pass on the external data to it, then forward all callbacks to it at the appropriate time.
-
Yeah exactly, scrolling history

This might be my best option as I realised I simplified my explanation: The graph I am trying to draw is a bit more complex than simple history, I need to be able to redraw the whole graph with different data at certain points, so I guess it's not really a history graph
I'll try and do what you said here, although I've not done this before and I'm not entirely sure what you mean : )
-
@griffinboy I'm happy to help, hit me up over DM. It's super-easy to do what you'd like. Though my first suggestion, assuming that's what you want, is to adapt the tile @Christoph-Hart is using for HISE.
-
I'll message, thanks for the offer
-
@griffinboy Yes. First, pls take a look at my commercial spectral editor, Steinberg's SpectraLayers. If you want to do anything you see in that programme, obviously I can be pretty specific. If you'd like a license for it, let me know.

@clevername27 I've done similar stuff using a peak FFT external buffer, though I'm concerned about the efficiency of my code.
From the top of my head it was as simple as keeping an array of data updated by push/pop new/old external buffers. But then the paintRoutine behind has A LOT of data to draw! So it works, but the GPU probably hates me...
Would there be a more efficient way? And if you add a blur then...
Of course the data has first to be downsampled to whatever the resolution of the panel is, but still the paintRoutine can be sometime a painRoutine

That's the thing, it's all being drawn on the CPU. That's the problem. I don't know if JUCE 8 finally solves this.

Don't.... At least until Melatonin Blur gets implemented. If you have to, use drop shadow to fake blur on paths, but even that (except the text one, which uses Melatonin) is going to be somewhat hungry.
-
@aaronventure oh yes I always forget that the CPU is in charge… pity…
Yeah I simply dropped the stock blur for a long time, eager to see melatonin being implemented more deeply
