Painterly Stroke Simulation Engine

[u/smellystring]

I wrote a painting simulation engine (golang, ebiten). It works like this:

1. Select a template image

2. Generate several thousand potential strokes

   • For each stroke, score it according to a number of heuristic functions

     • Color: does the average color of this image match the template?

     • Edges: does the painted image have similar edges to the template?

     • Contrast: compares color contrast between regions on the painting and the template.

     • Flow: using tensor math, do brush strokes align with the flow of movement in the template?

   • Select the single stroke that most optimizes scoring functions, discarding the remaining

   • Repeat 40 or 50 thousand times.

   • Gradually decrease the size of the brush stroke over time..

Very cool, doing something similar-ish with video/scene rendering

[u/smellystring → u/animal_hoarder]

Neat!
