Creative Coding with Compose The Next Chapter
summary
Uses Jetpack Compose canvas and polar math to generate polygons, adds randomness and repetition to produce hundreds of layered variations, and implements a stateful canvas via ImageBitmap + drawWithCache/drawBehind so drawings accumulate instead of clearing. Applies AGSL noise shaders via runtime shader (API 33+) to add grainy texture, exposes intensity controls, and experiments with blend modes; captures results with PixelCopy (API 28+). Workflows powered by a small control panel and iterative randomness, produced many successful January generative pieces, with ChatGPT used for code ideas.
