Classpublic final class SinePlasma
ImplementsIFilter

The SinePlasma class is a filter that generates a plasma based on non-distorted sine waves.

The formula of this filter is new = ( 0x7f + 63.5 * sin( frequencyX * x ) + 63.5 * sin( frequencyY * y ) ) * amplitude.

This filter is based on a technique from toxie^ainc. and the C++ implementation from Hopper.

Supported formats:


Example 
  
  var filter: SinePlasma = new SinePlasma();
  
  var image: Image = new Image( 160, 120, ImageFormat.RGB );
  
  filter.apply( image );
