Abstract fractal snowflakes using an iterated function system.
Soundtrack from Forty Words For Snow (2007), made with Pd.
# 1 2024
Rebooted in 2024, I ported the fractal shapes from PostScript to custom C + OpenCL code calculating an iterated function system.
Compared to 2008:
- higher resolution and framerate with better codec;
- aspect ratio from 4:3 -> 16:9;
- less basic animation sequencing;
- slower (especially rotation);
- automatic rescaling of transforms to a target fractal dimension;
- automatic transformation probability weights for even fill;
- motion blur;
- added a circle inversion transformation to get some curves and fill out the background.
