I was just sitting there toying around with the decimate modifier when I thought that using it for an audio visual animation would have been pretty interesting. So I did.
Hello everyone, thank you for your interest.
Regarding the workflow, I’m not at all good at scripting so I used none. The animation is based on animated modifiers.
I baked the audio track I had to the strength of a displacement modifier (as I already did in a previous video on my channel), the rest is animated kind of manually.
I set the displacement’s mapping to an empty, which I animated by hand (Alt+A, G with automatic keyframe insertion, so baked the motion I gave it).
I added two decimate modifiers which I animated manually according to the track I used. Explaining further, I set one to 0.2, the other at 1.0 at the start of the animation, to 1.0 and 0.2 at the end to give a flickering effect (something like animating a seed but less drastic). Then I manually decimated more or less where I decided it fit the audio.
I added a wave modifier, setting the speed to match the rhythm and manually animating the strength.
I added a second wave modifier, set the speed to 0, and animated it according to the bass. That causes the big “bumps” around the middle of the track.
Then I did some keyframing in the compositor and that’s it I suppose. Hope that was clear enough.
I’m not really sure if it’s the best or fastest way to do things, and it’s kinda fiddly, requires a lot of tweaking, and really depends on the audio track, but in the end it’s all fine to me.
Again I am really sorry for the poor resolution.
