glowing effects

[kaanersan]

Hi developers,

First thank you for creating such cool visualizations.
I'm going to be making a presentation on winamp plug-in development. I was just wondering how are those glowing effects are made on visualizations? Not just basic vector graphics but the glowing effects kind of like light effects fading into black background usually.

Any help is very much appreciated.
Cheers,
Kaan

you can achieve such effects by processing the image from the previous frame. You can smoothly fade a color to black by multiplying it by 0.95 each frame.
static glow is possible since Pixelshader support mixing different blur levels to the final output.
