论文摘要

血浆分形是一种生成随机和逼真的云,纹理和地形〜的技术 - 传统上使用递归细分。我们根据迭代扩展展示了一种新方法。它提供了包括标准的Square-Diamond算法的一系列算法,并提供了各种有趣的扩展方法,从而产生了更好的图片。该方法是由于从数组语言的角度探索等离子分形的目的(我们以OCAML中的嵌入式DSL实现)〜-从声明整个图像转换的角度来看,而不是用单个像素来摆弄。

Plasma fractals is a technique to generate random and realistic clouds, textures and terrains~-- traditionally using recursive subdivision. We demonstrate a new approach, based on iterative expansion. It gives a family of algorithms that includes the standard square-diamond algorithm and offers various interesting ways of extending it, and hence generating nicer pictures. The approach came about from exploring plasma fractals from the point of view of an array language (which we implemented as an embedded DSL in OCaml)~-- that is, from the perspective of declaring whole image transformations rather than fiddling with individual pixels.
