A Star Field
can be rendered with this function. It combines multiple randomly placed
and scaled stars with a background noise, which can simulate Nebulae or
the Milky Way.
Modify the number of overall
number of stars with the Density parameter. By increasing
the Roughness value, you can add smaller stars to the
pattern. Scale all stars with the Size attribute.
You can cause the star field to be distorted by a noise if you
increase the Distortion parameter. This results in a fluid
effect like shown in Image 3. An underlying Noise can be
added by regulating the value of the same name.
manipulates the contrast and intensity of the stars.
