entropybrush doesn't fake brush marks with filters. It simulates the oil paint itself: loaded bristles, wet flow, drips, and thick impasto relief you can tilt and light in 3D.
No account. No sign-in. No data collection. Just paint.
Every stroke lays down real volume. Tilt the canvas to see ridges of thick paint stand off the surface, move the light to rake across the texture, and watch wet paint ooze, drip, and settle like the real thing.
A stroke carries a load of paint that thins and runs out as you drag, so marks start rich and end dry.
Paint levels, blends wet-on-wet, and dries over time. Set the dry time to zero and it sets exactly as brushed.
Thick paint builds genuine height. Light it, tilt it, and export the painted surface as a 3D model.
Colours combine subtractively, like real paint. Blue and yellow make green; white tints, medium glazes.
Spin the canvas and fling wet paint outward into centrifugal spirals, then square it back up.
Tilt the canvas and let loaded paint run. Rake a light across the surface to reveal every ridge.
The relief you see is the simulation's own height map, lit per pixel. Nothing is a texture stamp. That is why you can orbit around a painting while it is still wet, and why the exported STL or GLB is the painting itself.
Paint with one hand and orbit the canvas with the other. Everything is direct manipulation, and Apple Pencil works on iPad.
Free on the App Store for iPhone and iPad. Runs entirely on your device, offline, with nothing collected.
