Fractal flames are a member of the iterated function system class〔Mitchell Whitelaw (2004). ''Metacreation: Art and Artificial Life''. MIT Press. pp 155.〕 of fractals created by Scott Draves in 1992.〔(【引用サイトリンク】title=Information about Apophysis software )〕 Draves' open-source code was later ported into Adobe After Effects graphics software〔Chris Gehman and Steve Reinke (2005). ''The Sharpest Point: Animation at the End of Cinema''. YYZ Books. pp 269.〕 and translated into the Apophysis fractal flame editor.〔 Fractal flames differ from ordinary iterated function systems in three ways: * Nonlinear functions are iterated in addition to affine transforms. * Log-density display instead of linear or binary (a form of tone mapping) * Color by structure (i.e. by the recursive path taken) instead of monochrome or by density. The tone mapping and coloring are designed to display as much of the detail of the fractal as possible, which generally results in a more aesthetically pleasing image. == Algorithm == The algorithm consists of two steps: creating a histogram and then rendering the histogram. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「fractal flame」の詳細全文を読む スポンサード リンク
