Updated Poissonlike generator with GUI and more
Just a super short note: I updated my simple renderingoriented Poissonlike 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

Poisson disk/square sampling generator for rendering
I have just submitted onto GitHubÂ small new script – Poissonlike distribution sampling generator suited for various typical rendering scenarios. Unlike other small generators available it supports many sampling patterns – disk, disk with a central tap, square, repeating grid. It … Continue reading
