This page is for creating artistic images using two dimensional noise.
The sliders control the parameters of the noise function.
First, a random noise gets generated. (Noise: randomess, but not completely random)
It just creates a smooth pattern. Then, Frequent Browniam Motion gets applied.
That just means, different frequencies (scales) of the same noise get overlayed together, N times.
After that, a concept called domain warping gets applied. Domain warping is a technique that changes the shape of the noise.
That's it.
Change the Sliders to whatever Values you like.
Click the "Render!" button to see the result rendered.
Optinally, you can also export the image as a PNG file.
Noise Scale just modifies the scale of the output noise, higher values resulting in a more zoomed-out image.
Does pretty much nothing, yet I still keep it in the code.
The Frequency is just the initial Frequency (mentioned above) the FBM algorithm starts with.
The Octave Count is the number of times a layer of noise gets applied (mentioned above).
Every Octave, the Amplitude gets multipled with persistance, so persistance basically means how much parts of later Iterations get added.
Smaller Values; Later Octaves are not that visible in the final noise image.
Every Iteration, the frequency (mentioned above) get multipled with lacunarity. So, the higher the lacunarity, the higher the frequency gets over time with every iteration.
This is the number of times the Domain Warping gets applied. Really, values dont need to be above 2, since there is no real difference in the output image.
Every time domain warping gets applied, the scale (next slider) gets multiplied by falloff.
Really just how strong the domain warping effect is.
If you want to use a custom colormap (not the default blue/pink colors, but a custom color), click this button to toggle.
The red, green and blue values of the color. If unsure, use any online color picker like here, and just pick a color you want.
Then if you see any RGB or Red, Green and Blue values, (usually notated like rgb(RED, GREEN, BLUE)
) just copy them over to the sliders.
This is the seed of the random noise generator. It is random every time, using the same seed will result in the same exact image every time.
If you want to change the seed, click this button.
This Button renders the image. Note that you can also change the sliders while it is rendering.
Exports the Image as a PNG file.
