Fractals in HLSL
Here's an interesting little shader I wrote today, initially as an attempt to render the Mandelbrot Set in real-time. Unfortunately, my attempt failed somewhere along the line, because the output set only vaguely resembled the famous Mandelbrot image. Instead of quitting, I played around with the equation and came up with some interesting, real-time morphing fractals. Couple that with a little bloom filter and color transformation, and you've got a pretty nice little image.
Pixel shaders amaze me.
