ACID TRIP - Unity music visualiazer

ACID TRIP - Unity music visualiazer from ciphered on Vimeo.

I feel like drowing and reaching extazy while watching these visuals. Sometimes, the void reaches you, but in the following seconds you see what you think is the most beautiful thing you have ever seen. The life is always a balance of these two feelings. Most of the time, the two of them coexist in a nuanced way, and occasionally jumping from one to another. I would like to find the perfect balance. And then carry that weight to the top.

I made this vusal to picture how I currently am feeling. And overall it turned fucking beautiful for some reason, so yeah I'm happy about that too. But for this one, the main direction was trying to control at best what I was doing, to shape the result in the directions I wanted. Random adjustments created something I didn't expect but decided to keep

I just wanted to talk a bit about the creative process behind the creation of visuals using code. Often, what you had first in mind turns into a completly different piece. Because the mind can't imagine the effect of the parameters behind the mathematics, toying with them sometimes result in unexpectedly beautiful results. Most of the time it turns into shit you also have to be lucky and try to modify everything to only keep what you want.
I didn't expect to make something that trippy when I started this project but adding ideas on to another, i got this. Unexpected yet interseting.

Technical aspects
This was made using unity.
A shader computes a reaction diffusion algorithm over a frame used as a feedback to the same shader. Fast way to run a reaction diffusion.

Textures and dots, reacting to the audio signal, are added as chemical B to the reaction, creating these patterns reacting to the audio.
A force field, generated using a simplex noise, is also used as a displacement map for the reaction-diffusion shader. This creates the movement in the scene.
Color are computed so that they sort of follow the chemicals reaction. This result in a creepy matter, very organic.
Post processing effect are added such as bloom, hue rotation, grayscale, pixellation, mirror, chromatic aberation, lens distortion.
On top of that, a shader apply color operations between the current frame and the last frame. The resulting frame is displayed on the screen.
