分形/fraktaler-3

Fraktaler 3 是一个

• 跨平台 (Linux, Windows, Android, Web)
• 由 Claude Heiland-Allen 开发的分形程序
• 用于对混合逃逸时间 2D 分形进行快速深度缩放。

它有一个使用 SDL2、OpenGLES 和 Dear ImGUI 的图形浏览器，以及一个用于高分辨率图像和缩放序列的批处理模式，可以选择以与 Kalles Fraktaler 2+ 和 zoomasm 兼容的 EXR 格式导出原始数据。

帮助

fraktaler-3 --help 的输出

用法

 fraktaler-3 [mode] [flags ...] [inputfile [inputfile ...]]

操作模式

 -h, --help                print this message and exit
 -V, --version             print version information and exit
 -i, --interactive         interactive graphical user interface
 -b, --batch               command line batch processing
 -W, --generate-wisdom     generate initial hardware configuration
 -B, --benchmark-wisdom    benchmark hardware for optimal efficiency
 -S, --export-source       export this program's source code

标志

 -v, --verbose             increase verbosity
 -q, --quiet               decrease verbosity
 -p, --persistence file    path to persist state
 -P, --no-persistence      don't persist state
 -w, --wisdom file         path to wisdom

输入文件在命令行中按顺序合并 帮助文本将列出系统上持久性和智慧文件的默认位置，以及 --export-source 选项的文件名。

可以在命令行上指定多个参数文件。加载持久性后，它们将按顺序合并（后面的文件会覆盖前面的文件）。这允许您在不同的文件中保留参数的不同方面。

变换

• 指数映射 功能在图形程序中不太有用，但可以在命令行版本中用于渲染缩放序列，以便稍后使用 zoomasm 将其组装成视频
