Plasma node

This documentation is for version 2.0 of Plasma (net.sf.cimg.CImgPlasma).

Description

Draw a random plasma texture (using the mid-point algorithm).

Uses the ‘draw_plasma’ function from the CImg library, modified so that noise is reproductible at each render..

CImg is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications (see http://cimg.eu).

Controls

Parameter / script name	Type	Default	Function
Alpha / alpha	Double	0.002	Alpha-parameter, in intensity units (>=0).
Beta / beta	Double	0	Beta-parameter, in intensity units (>=0).
Scale / scale	Integer	8	Noise scale, as a power of two (>=0).
Offset / offset	Double	0	Offset to add to the plasma noise.
Seed / seed	Integer	2000	Random seed: change this if you want different instances to have different noise.
Static Seed / staticSeed	Boolean	On	When enabled, the dither pattern remains the same for every frame producing a constant noise effect.
(Un)premult / premult	Boolean	Off	Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
Invert Mask / maskInvert	Boolean	Off	When checked, the effect is fully applied where the mask is 0.
Mix / mix	Double	1	Mix factor between the original and the transformed image.
