Strange Attractor

Strange attractor is the most utilized tool, 99% of the museum collection were created using this paint. It has plenty parameters and looks a bit involved. But this is price of its flexibility. When an attractor is created two sections must be parameterized. The first section defines color animation. The second one creates a divergence function:

Attractor length of animation

energy of red of green of blue

frequency of red of green of blue

phase of red of green of blue

quality of red of green of blue

divergence harmonic or

Fourier or

pyramid

Remarks

Energy defines how quickly colors change. The more energetic colors used the faster picture closes to a mess. Normally energy of a color lays in range between 0.01 and 1.0.

Colors fluctuate as a harmonic function. Frequency is a positive number that reflects number of "peaks" it has. It may be a fractional number. Normally 1.0 is used. Phase parameter moves the peaks forth and back. It's a number expressed in either radians or degrees.

Quality may vary from nearly zero up to 100.0. It reflects the sharpness of harmonic peaks. The lower quality the smoother energy fluctuates. Zero quality flattens the function and is nonsense.

Divergence function defines design of the painting.
