Demo: New View on Plasma Fractals -- From the High Point of Array Languages
summary
New approach presents plasma fractals as a family of image-expansion algorithms (so the standard square-diamond algorithm sits alongside bilinear and bicubic enlargers) and implements them as an embedded DSL in OCaml that declares whole-image transformations. It replaces recursive subdivision with iterative noisy expansion, models bilinear/cubic/diamond steps as 2D convolutions, exposes a noise parameter (reported around NSF 1.1–2.2) that controls roughness, and generates demo images that remove diamond artifacts and produce visibly smoother, more varied fractal textures.
