The Developer Tested the Approach on a Sample Photo, Iterating on Ideas to Refine the Output

A developer built an interactive digital painting tool that uses edge detection to guide brush strokes, rendering images as layered 2D Gaussian splats. The project, detailed in a blog post, adapts an earlier edge-aware pixelation technique to generate paintings without slow gradient descent methods used by existing tools like DrawingWithGaussians. The tool traces image edges to determine stroke placement, size, and direction, then renders splats with alpha compositing to avoid white blobs from additive blending.

The developer tested the approach on a sample photo, iterating on ideas to refine the output. The post explores what worked and what didn't, aiming to see if the result resembles a real painting.
