Take for example a Circle and what if you can control its position in a plane, Radius, Hue (Color Shade) and its Opacity (or Transparency).
Definition of Hue from Wikipedia: “Hue is one of the main properties of a color, defined technically , as “the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, green, blue, and yellow,” (the unique hues). The other main correlatives of color appearance are colorfulness, chroma, saturation, lightness, and brightness.” http://en.wikipedia.org/wiki/Hue
I have made an array of many circles with each circle having 4-Fold randomness.
- Randomness in position. (x between -15 and 15 units, y between -15 and 15 units)
- Randomness in Hue (between 0 and 1 )
- Randomness in Radius (between 0 and 1 units)
- Randomness in Opacity (Between 0 and 1)
The two figures below are generated by the same program run at different times. Because of the random variables, the image generated each time will be unique.
If you look at the images you might get an illusion that the disks are situated in a 3-D Space with some of them behind in your view and some towards you. This is because of the opacity which adds a whole new thing to the Hue.
The image below has been generated with a certain range of the Hue so that all the circles’ colors vary only little.
The below image is an animation in which the number of points progressively increases. (The Image loops to beginning once the animation is finished.)
