Why did nobody tell me that the 16 bit noise looks SO much better than the 8 bit version?!
Just working on a SmartMatrix noise playground.
Way better structured than FunkyClouds was.
Full palette support.
Every animation is now basically just a set of (pretty many) parameters which makes it fun to play with.
More to come.
Btw, how many faces do you see in the video?

That’s awesome!
Looks like fabric ripples. How do you manipulate the noise to get it to go in one direction? Do you leave the Z axis alone and increment others? Too cool!
Z is not touched. Instead of many words just the code. That is the complete parameter handling:
void Lavalamp1() {
PaletteRed();
noisesmoothing = 200;
x[0] = beatsin16(3, 200, 64000);
y[0] += 100;
z[0] = 7000;
scale_x[0] = 6000;
scale_y[0] = 8000;
FillNoise(0);
x[1] = beatsin16(2, 200, 64000);
y[1] += 130;
z[1] = 7000;
scale_x[1] = 6000;
scale_y[1] = 8000;
FillNoise(1);
x[2] = beatsin16(4, 200, 6400);
y[2] += 1000;
z[2] = 3000;
scale_x[2] = 7000;
scale_y[2] = 8000;
FillNoise(2);
MergeMethod1(2);
}
The first 2 layers get overlaid for the color, the 3rd on is a brightness mask.
Are you using the Gamma Correction feature in SmartMatrix? It’s on by default in SmartMatrix, but the FastLED SMART_MATRIX controller turns it off by default. It could make a big difference in a pattern like this.
The FastLED_Controller example included with SmartMatrix shows how to enable Gamma Correction
Now I´m using it. That makes indeed a huge difference, thank you for the hint, Louis!
The Gamma Correction maps a 24-bit color into a 36-bit color space (or 48 if you modify a header file but it costs CPU and memory and doesn’t make a big difference). Fades to and from black should look much better with Gamma Correction on.
Cool. So if I initialize the SM as a FastLED controller with gamma correction switched on it internally calculates and uses automaticly the 36 bit space, right? I ask because I get less fps now. 43 vs. 54 with 3 noise layers.
Yes, it’s done on the fly one row at a time while refreshing. You can switch it on and off while your sketch runs if you want to compare the effects.
code would be great 
@Anton_Mulidran Oh but he did! You have to look for it under this thread. He shared the process for how he went about and offered a solution. The fun part should be trying to figure it out on your own, at least that’s what I call fun…sheesh
@Jon_Burroughs
My bad I didn’t see part of code he posted.
