Pixel Bender visualizer
All credits for this code and swf go to Eduardo Omine.
I ablsolutely love his work and just wanted the c ommunity to see this and work on it.
it is a brilliant use of peak values of the mp3 along with pixel bender filters.
This is only for the community to see and i do not intend to violate any rights / laws.
Change values and get different results, the pixel bender filter has values size,angle,dx,dy
shader.data.size.value = [float value];
shader.data.angle.value = [float value];
shader.data.dx.value = [float value];
shader.data.dy.value = [float value];
multiply size by peak and dx and dy by posX and posY
todo - get it to work with computeSpectrum
