Title: Iteration Fog Post by: Patryk Kizny on June 23, 2015, 05:17:15 PM Hey,
Mandelbulber3D has a cool feature called iteration fog. It's a volumetric where the density of the fox and scattering is related to the iteration of the fractal and it wraps the fractal. I wonder how could this be implemented in GLSL for Fragmentarium. Any thoughts? Title: Re: Iteration Fog Post by: Syntopia on June 23, 2015, 06:24:05 PM There is simple 'glow' effect in Fragmentarium where the glow is based on the number of ray step iterations taken (so something closer to the fractal use more iterations). I imagine this ray step iteration count is also used by M3D for fog density (though minimum DE distance would make more sense?) However, it is not a participating media, and will not be light by any light sources, so it is quite boring. For volumetric fog, take a look at this thread: http://www.fractalforums.com/fragmentarium/updating-of-de-raytracer/ |
