This applet visualises a famous plasma effect.
[For more technical
information about the available parameters, click here.]
Most parameters are self-explanatory and you can
always see brief description of each parameter by moving the mouse
pointer over the wizard.
First, define the applet size and its resolution "Width",
"Height", and "Resolution".
Resolution works as a stretcher value for the internally calculated
image. If you want high quality result, set this to one.
Then you decide if textscroll function is
enabled by checking "Enable textscroll" box.
You can change the rotation speed of the plasma
at "Speed" parameter.
||Plasma is generated
by 3 different generators Gen1, Gen2, Gen3.
Gen1 is a smoothing parameter, with which fog and psychedelic
effect in two extreme cases can be achieved.
Gen2 and Gen3 are xy stretchers respectively.
As for colouring, we provide a little complex palette
system. I'm afraid, but I need to go a bit into math to illustrate
how the applet utilises colour.
Each RGB channel consists of three parameters. Consider
Rn, Gn, Bn (n=1, 2, 3) represent the available
9 parameters for the palette system. The final palette is determined
by the following formula:
|Red = (sin(r*PI*2/(256/R3
Blue = (sin(r*PI*2/(256/B3 ))*B1 )+B2
Here, r steps from 0 to 255. R1, R2, G2, G2, B1,
and B2 range from 0 to 255, while R3, G3, and B3 rage from 1 to
There isn't easy way of explaining this, but I recommend
you to experiment various values starting with the default setting
until you get the palette you want.
Proceed to the textscroll
menu if you have checked the textscroll box; otherwise go to
the expert menu.
