golden spiral

Another image made with the recent stone filter pack.

Somehow the dark stone texture looks a bit more like leather exported at high resolution.


Image was drawn in inkscape 0.92. The spiral itself is built up from linear gradiented circle sectors of 1 gon turns. The rainbow effect is made by a gradient map filter applied on a spiral made from gradient meshes, which got masked and clipped.


Will upload the svg sources from the intermediate steps soon.

snail shell

Revisited the older concept of a snail-fractal.
Previously made it from random objects and retouching the filtered image was a larger part in gimp.

This instead, is based on the proportions of the Fibonacci spiral.
However that results in a totally unnatural look, contrary common misinformations.

It was drawn in inkscape with gradient meshes, but after a full rotation the rendering got so slow that used raster copies further on. So this time no svg source (as it was quite sloppy as well).

Using a recent stone filter in the background.
