It's a creative coding art of glass dishes.

Creative coding artwork of beautiful kaleidoscope or glass dish.

It's a creative coding artwork made with the 'Processing'. It draws a beautiful shape like a kaleidoscope or glass dish.

Many circle with the Perlin noise controlled radius form this shape. And the key of this shape is here.

  int radDiv01 = 3 + floor(random(2.0)) * 2;
  int radDiv02 = floor(random(6.0, 10.0));

 

An example code of the 'Processing'.

This code does not display any images on the screen but generates image files in frames directory.

Please feel free to use this example code under the terms of the GPL. To see other works based on my code is my pleasure. And my honor.
