Posted on September 5, 2014 by bartwronski

Just a super short note: I updated my simple rendering-oriented Poisson-like pattern generator with: Very simple GUI made in PyQt to make experimenting easier. Option to do rotating disk (with minimizing rotated point distance) for things like Poisson bokeh / … Continue reading →
