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).

Function |
---|---|---|---|
Alpha / |
Double |
0.002 |
Alpha-parameter, in intensity units (>=0). |
Beta / |
Double |
0 |
Beta-parameter, in intensity units (>=0). |
Scale / |
Integer |
8 |
Noise scale, as a power of two (>=0). |
Offset / |
Double |
0 |
Offset to add to the plasma noise. |
Seed / |
Integer |
2000 |
Random seed: change this if you want different instances to have different noise. |
Static Seed / |
Boolean |
On |
When enabled, the dither pattern remains the same for every frame producing a constant noise effect. |
(Un)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 / |
Boolean |
Off |
When checked, the effect is fully applied where the mask is 0. |
Mix / |
Double |
1 |
Mix factor between the original and the transformed image. |
