13.4.1. Overview

图 17.284. Example of a rendered plasma

Filter “Plasma” applied

All of the colors produced by Plasma are completely saturated. Sometimes the strong colors may be distracting, and a more interesting surface will appear when you desaturate the image using Colors → Desaturate.

13.4.3. Options

图 17.285. “Plasma” filter options

Preview: If checked, parameter setting results are interactively displayed in preview.
Random seed: This option controls the randomization element. The Randomize check-button will set the seed using the hardware clock of the computer. There is no reason to use anything else unless you want to be able to repeat the exact same pattern of randomization on a later occasion.
Turbulence: This parameter controls the complexity of the plasma. High values give a hard feeling to the cloud (like an abstract oil painting or mineral grains), low values produce a softer cloud (like steam, mist or smoke). The range is 0.1 to 7.0.
