Epsilon, a 64k intro by Mercury

Last weekend the demogroup Mercury released at Tokyo Demo Fest the final version of their invitation to the upcoming Revision party: a 64kB demo called Epsilon. While the complexity of the scenes is very limited, the rendering, seemingly a raymarching shader, features a couple of very noteworthy real-time effects including ambient occlusion, reflexion (up to two iterations it seems) and refraction, caustics, and an hexagonal bokeh depth of field.

  1. Maximum reflection depth is eight iterations in the final – two iterations in the party version – I forgot to change the constant there…
    Six iterations for refractions – because you don’t need more for those scenes.
    It’s a mix of standard raytracing intersection tests and sphere tracing.

  2. And of course: thank you for writing a blog post dedicated to our intro – seems you are one of the first to do that!
