How to soften a 2d matrix effect?

Other Hardware LEDs and Multiplexing
1

Just wondering, how to visually calm this animation.

Linear filtering? Antaliasing? What would you do?

An example how it appears right now. I mean, it looks not bad, but I would like to have it even smoother.

It runs with arround 150 fps on 1024 leds with 36 bit color depth - so there is still space to do some fancy math.

Inspiration appreciated! Any thoughts?

Thanks,

Helmuth

P.S. I´m not talking about the flickering - this is caused by an interference between the multiplexing and the cameras fps.

Looks nice. I would just slow it down or filter in the time domain. Anything else will change the overall appearance and that's a subjective judgement - do you like more blue?

Some iterations later: slower, more detailed + multi layer based

I would use antaliasing to generate intermediate frames.

Ha, synchronicity!

I played yesterday with this idea in order to produce very smooth transitions.

The key was to calculate everything on a base of 256 fractions between the integer steps.

Now I need a better color-/gamma correction which allows that 2 leds at 50% are exactly as bright perceived as one led at 100% brightness.

This might become tricky due to a different human sensitivity to different colors and the different led characteristics itself.

I´ve no idea yet how to start with a decent calibration. It might need a couple of test pictures with gradients in order to bend the curves into the right S-shapes.
